What's New in Retrospect – Retrospect Backup 19 + Retrospect Virtual 2022 + Retrospect Cloud Storage

Microsoft 365 Agentless Guide

Overview

Retrospect Virtual allows you to back up your Microsoft 365 data on the cloud without the need to deploy a backup agent. You can access the Retrospect Virtual Console server environment easily on a web-based management console. This is a user interface that allows you to login remotely to a backup server to manage and monitor your backups.

Running your Microsoft 365 backup on Retrospect Virtual Console provides the following advantages:

Web-based Management Console: Our enriched features on the centralized user web console offers you a one-stop location for monitoring and managing your backup and restore, whether you are a system administrator or a backup user. Below is an overview of what you can do with it.

  • Create backup set

  • Restore backup

  • Configure user settings

  • Configure backup settings

  • View and download backup and restore reports.

  • Performance

The Change Key API has significantly improved backup performance of backup jobs, which means backup sets with a large number of Microsoft 365 accounts for backup can be completed within hours.

Live Activities Monitoring Feature: The Retrospect Virtual Console User Web Console has a live activity monitoring feature which is used to keep track of the backup and restore job(s). The following operations can be performed using this feature:

  • View the status of the backup process that is currently running

  • View the status of the restore process that is currently running

NOTE: There is an update interval of around five (5) seconds for both backup and restore activities.

No Additional Hardware / Device Required: As the Run on Server (agentless) backup set utilizes the resources of the Retrospect Virtual Console backup server, there is no need to provision additional physical or virtual machine to run the backup/restore which means the cost of each backup set is much lower than for an agent-based Microsoft 365 backup set.

Easy to Manage: The Retrospect Virtual Console User Web Console offers you an easy-to-manage user interface. This will help you save time, and it reduces the overall cost of support.

Backup Set Management from any Device (Accessibility): Backup/restore operation(s), backup set settings configuration, and backup/restore process monitoring can be done from any device as long as a web browser and internet connection are present in the device.

Backup of Selected Items: To back up the Microsoft 365 user accounts, the backup resources can be user level, site collection level and even item level.

  • Flexible backup options: Only select the required users, specific site collection or items for backup.

  • Flexible restore options: Restore all the users or just one user or restore the whole site collection or just one site or restore the whole user content or just one item. Or restore items to the original location or an alternate location.

Fast and Efficient: We understand that backup could be a time and resources consuming process, which is why Retrospect Virtual Console is designed with advanced technologies to make backup a fast and efficient process. We also understand that you may wish to run backup at a specified time interval of your choice, that’s why we also allow you to set your own backup schedules so that you can take full control of the time when to perform backup.

Multi-threading – this technology utilizes the computing power of multiple CPU cores for creating multiple backup and restore threads to produce fast backup and restore performance. The default setting for Microsoft 365 backup sets supports a total of 4 threads per backup job.

Higher Reliability: The implementation of one index file per user can significantly improve the overall resilience of backup and restore from index related issues. For example, if a single index file becomes corrupted, it will only affect corresponding user, while other users selected for backup are unaffected.

File Transfer Security: The Retrospect Virtual Console comes with a secure file transfer method using the https protocol that guarantees the highest level of security measure in safeguarding the movement of files from the backup source (Microsoft 365) to the backup destination (Retrospect Virtual Console server).

High Level of Security: We understand your Microsoft 365 users may contain sensitive information that requires to be protected, that is why your backup data will be encrypted with the highest level of security measure.

Encryption Key – to provide the best protection to your backup data, the encryption feature which by default will encrypt the backup data locally with AES 256-bit truly randomized encryption key.

Cloud Destinations Backup: By default, the Retrospect Virtual Console is set as the storage destination in creating an Microsoft 365 backup set. However, you have the option of selecting another storage destination as provided by your cloud service provider.

Compliance: Some organizations do not permit the installation of third-party applications on production environments due to regulatory requirements. An agentless solution allows for compliance during backup or restore.

Less Resources Needed: Backup client agent could interfere with the processing power of core applications of the machines that it is installed on. Run on Server Microsoft 365 backup job is performed on the backup server, which does not consume resources on client computer during a backup job.

Run on Server: A Run-on Server Microsoft 365 backup set provides you with an agentless backup solution. Manual schedules are performed directly by the Retrospect Virtual Console backup server; you do not need to install a backup agent on your personal computer in order to back up your data on cloud storages.

Run on Server backup and restore can be managed on a computer or device running on Windows/MacOS/Linux /iOS/Android as long as the device is able to support a web browser and has an internet connection.

Differences between a Run-on Server and Run-on Client Backup Set: The following table summarizes the differences in backup options available between a Run-on Server and Run-on Client Microsoft 365 backup set, and the tool to use (web console or client agent) when performing a backup and restore:

Getting Started

This document aims at providing all necessary information for you to get started with setting up your system for Run on Server (Agentless) Microsoft 365 backup and restore, followed by step-by-step instructions on creating backup set, running backup job, and restoring backed up data, using the Retrospect Virtual Console User Web Console.

The document can be divided into six (6) main parts.

  1. Preparing for Microsoft 365 Backup & Restore

  2. Performing a Microsoft 365 Backup

  3. Restoring a Microsoft 365 Backup

  4. Running a Data Integrity Check

  5. Deleting Backup Data

Preparing for Backup and Restore

Login Credentials to Microsoft 365

To allow access to Microsoft 365 (backup source) in performing a backup, make sure to have the correct login credentials to Microsoft 365.

Valid Retrospect Virtual Host Server User Account

A valid Retrospect Virtual Host Server user account is required before you can access the Retrospect Virtual Console User Web Console. Please contact your system administrator for more details.

Add-on Module Requirements

Make sure that the Microsoft 365 Backup feature has been enabled as an add-on module in your Retrospect Virtual Host Server user account and there is enough Microsoft 365 Backup license quota to cover the backup of the users.

The licenses for the Microsoft 365 module are calculated by the number of unique licensed or unlicensed Microsoft 365 user accounts. If same Microsoft 365 account is backed up on multiple backup sets with an Retrospect Virtual Host Server user account, it would be counted as one Microsoft 365 license.

  • Each licensed or unlicensed Microsoft 365 user account selected for backup requires one Microsoft 365 license.

  • Each Equipment Mailbox, Room Mailbox, or Shared Mailbox selected for backup requires one Microsoft 365 license.

  • If just only SharePoint Sites under the Site Collections and/or files of folders under Public Folder are selected for backup, this requires zero Microsoft 365 license but a minimum of one Microsoft 365 license is needed to perform a backup. The Microsoft 365 license is only needed to start the backup but it will not be counted as used license.

However, if any items from either Outlook, Items from OneDrive, or Personal Sites under Users are selected for backup, the Microsoft 365 license count will be calculated based on the number of user account selected.

Backup Quota Requirement

Make sure that your Retrospect Virtual Host Server user account has sufficient quota assigned to accommodate the storage of the Microsoft 365 users for the new backup set and retention policy. To get an accurate estimate of the backup quota requirement, it is recommended to check the actual usage of the Microsoft 365 Organization in the Microsoft 365 Admin Centre.

Data Synchronization Check (DSC) Setup

To compensate for the significant backup performance increase, there is a tradeoff made by the Change Key API, which skips the checking of de-selected files in the backup source, which over time can result in a discrepancy between the items or files/folders selected in the backup sources and those in the backup destination(s). However, the Change Key API will continue to check for de-selected Microsoft 365 user accounts or Site Collections. Un-selected individual Microsoft 365 user accounts or Site Collections detected during a backup job will be automatically moved to retention area.

To overcome this, it is necessary in some cases to run a Data Synchronization Check (DSC) periodically. The DSC is similar to a regular Microsoft 365 Change Key API backup job but with the additional checking and handling of de-selected files and/or folders in the backup source. So that it will synchronize the data in the backup source and backup destination(s) to avoid data build-up and the freeing up of storage quota.

Here are the pros and cons of performing the DSC:

Enabled

Disabled

Backup time

Since DSC is enabled, it will only run on the set interval. For example, the default number of interval is 60 days. The backup time for the data synchronization job which is trigger every 60 days by default will take longer than the usual backup as it is checking the de-selected files and/or folders in the backup source and data in backup destination(s).

As DSC is disabled, the backup time will not be affected.

Storage

Management of storage quota will be more efficient as it will detect items that are de-selected and move it to retention and will be removed after it exceeds the retention policy freeing up the storage quota.

Management of storage quota will be less efficient even though files and/or folders are already de-selected from the backup source, these files will remain in the data area of backup destination(s).

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image59.png

Authentication

To comply with Microsoft’s product roadmap for Microsoft 365, Basic Authentication (Authentication using Microsoft 365 login credentials) will no longer be utilized. Instead, all new Microsoft 365 backup sets created will use Modern Authentication.

Modern Authentication provides a more secure user authentication by using app token for authentication aside from using the Microsoft 365 login credentials. In order to use Modern Authentication, the Microsoft 365 account is registered under Global region and the Microsoft 365 backup is configured to use Global region. As both Germany and China region do not support Modern Authentication.

In order to migrate existing backup sets to Modern Authentication there are two (2) methods:

  • The first method is the Microsoft 365 account used for the backup set is assigned the Global Admin.

  • The second method is the Microsoft 365 account used for the backup set is an ordinary account. When changing the settings of the backup set, the user can ask a Microsoft 365 Global Admin to grant permission to authorize the migration of authentication. This is only required in migrating from Basic Authentication to Modern Authentication. This only needs to be done once per backup set.

To check the current authentication being used in your Microsoft 365 backup set, see criteria below:

Basic Authentication

If you click on the backup set and the following pop-up message is displayed, then the backup set is using Basic Authentication.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image60.png

Modern and Hybrid Authentication

For backup set using Modern or Hybrid Authentication, there is no pop up authentication alert.

Only the chat room that include the selected users and messages sent by the selected users will be backed up. If the messages contain attachments (Files), only the Files of the selected users will be backed up. It will not include the Files shared by other users that were not selected for backup.

This is a limitation with the Microsoft API, as the shared file is located in the other users’ OneDrive, which was not selected for backup.

To backup Teams Chat to include Files from all users in the chat, then all users who participated in the chat will also need to be selected for backup.

This Microsoft 365 user only

Chat rooms of the login user will be backed up, including messages from other users and from the login user. If the messages contain attachments (Files), the Files will not be backed up since they are located in OneDrive which was not selected.

Chat rooms of the login user will be backed up, including messages from other users and from the login user. If the messages contain attachments (Files), only the Files of the login user will be backed up, it will not include the files shared by other users since the other users were not selected for backup.

Here are some sample scenarios:

Example No. 1

You are required to backup Microsoft 365 user: Tom

Selection:

  • Backup Scope: Entire Organization

    https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image74.png

  • Microsoft 365 user: Tom

    https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image75.png

  • Data type: Teams Chat (assuming no Outlook or Personal Site data) and OneDrive

    https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image76.png

Scenario:

Tom is in a group Teams Chat which includes Amy, Joe and Teresa.

They chat about their project within the group, share files, etc.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image77.png

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image78.png

If you create a Backup Set and select only Tom; it will include only messages sent by Tom for the 1:1 group chat where Tom is included.

It will only include files that Tom had attached. It will not backup file attachments from the other three participants.

There will be Warnings after backup that items were not backed up when not all the users involved in the conversation are selected for backup. This is a sample of the warning that can be viewed from the backup report “Messages from users joe.smithson@lebshama.com in Chat “Joe SmithsonTom Smith,” will skip to backup cause users are not selected”.

Outlook
  • Online Archive Mailbox will NOT be supported for backup and restore.

  • For Outlook mail item, after using restore to original location to overwrite a mail item (the restored mail item is assigned a new mail ID), then in the backup source tree of the same backup set:

    • the original ticked item still uses the old mail ID to reference and becomes red item.

    • there is another item (with the new mail ID) created for that mail item

      To avoid future backup error/warning, the user will need to deselect the red item and tick the mail item again (new mail ID) in the backup source tree. This re-selection of backup source is not automatically done after you restore under overwrite to original location scenario.

Restore filter feature

Restore filter using Retrospect Virtual Console User Web Console is not yet supported.

Restore to Local machine

Restore to Local Machine is not supported using Retrospect Virtual Console User Web Console. It is only available using Retrospect Virtual Host Server.

Restore to Alternate location
  • Only administrator account or user account with administrative authority can restore backup items to an alternate location.

  • If you are trying to restore item(s) from one user to an alternate location user, Retrospect Virtual Host Server will restore the item(s) to their respective destination folder(s) with the same name as the original folder(s).

    • Example: Item from Outlook of User-A will be restored to the Outlook of the alternate location User-B; Item from SharePoint of User-A will be restored to the SharePoint of the alternate location User-B.

  • Restore of item(s) in public folder to an alternate location public folder is not supported.

    • Example: Restore of item(s) in public folder from User-A to alternate location User-B is not supported.

  • When restoring to alternate location, data type “Person or Group” will not be restored. Following restore, it is suggested revisiting the relevant settings if necessary. This also affects “Assigned To” column values of some list templates (e.g. Tasks list), and “Target Audience” column values of some list templates (e.g. Content and Structure Reports).

  • If you are trying to restore item(s) from several users to an alternate location user, Retrospect Virtual Host Server will restore the item(s) to their respective destination folder(s) in alternate location user with the same name as the original folder(s).

    https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image112.png

    Example: Item from Outlook of User-A and User-B will be restored to the Outlook of the alternate location User-C.

Restore to Alternate Microsoft 365 account

If you are trying to restore item(s) from multiple Microsoft 365 user account to an alternate Microsoft 365 user account, Retrospect Virtual Host Server can only restore one Microsoft 365 user account at a time.

Retrospect Virtual Console Run on Server (Agentless)

*Standard and Local Destination Settings

For the backup destination settings, only the Retrospect Virtual Console or predefined destination is supported in the Retrospect Virtual Console Run on Server (Agentless) backup.

It is not possible to assign other standard destinations such as the customers personal Google Drive, OneDrive, DropBox, Amazon S3, Azure, and other storage accounts as the backup destination for a Run-on Server backup set.

Reminder

The reminder feature is not supported in the Retrospect Virtual Console User Web Console. Unlike with the agent-based backup, when this feature is enabled, a backup confirmation dialog box will prompt the user to run a backup job during machine log off, restart, or shut down when Retrospect Virtual Host Server is installed on a Windows platform.

IP Allowed for Restore

This setting permits to predefine IP ranges that are allowed to perform restore as configured by the system administrator. This feature is only applicable in a Run on Client Microsoft 365 restore operation and is not supported in a Run on Server Microsoft 365 restore.

Space Freeing up

Space freeing up feature is used to remove obsolete file(s) from your backup set and destination. This feature is only applicable in a Run on Client Microsoft 365 Backup Set and is not supported in a Run on Server Microsoft 365 Backup.

Decrypt Backup Data

Decrypt backup data feature is used to restore raw data by using the data encryption key that was set for the backup set. This feature is only applicable in a Run on Client Microsoft 365 Backup Set and is not supported in a Run on Server Microsoft 365 Backup.

System Logs

Retrospect Virtual Host Server backup user account does not have access to the system logs related to the Data Integrity Check operation through the Retrospect Virtual Console user console.

Therefore, the backup user does not have the ability to verify the results of these operations without the assistance of the admin.

Best Practices and Recommendations

The following are some best practices or recommendations we strongly recommend you follow before you start any Microsoft 365 backup and restore on Run on Server (Agentless).

Performance Recommendations

Consider the following best practices for optimized performance of the agentless backup and restore operations:

Perform test restores periodically to ensure your backup is set up and performed properly. Performing recovery test can also help identify potential issues or gaps in your recovery plan. It is important that you do not try to make the test easier, as the objective of a successful test is not to demonstrate that everything is flawless. There might be flaws identified in the plan throughout the test and it is important to identify those flaws.

Concurrent Backup Thread

The value of 4 concurrent backup threads is found to be the optimal setting for Microsoft 365 backups to ensure best backup performance, minimal resource usage, and lowest probability of throttling of backup requests by Microsoft 365.

Recommended Number of Microsoft 365 users on a Backup Set

To ensure that your Microsoft 365 Run on Server backup set completes the backup job within 24 hours, it is recommended that a single Microsoft 365 Run On Server backup set should not contain more than 2,000 users. That is assuming that only small incremental daily changes will be made on the Run-on Server backup set.

Authentication

Since Modern Authentication is already available, it is recommended that backup sets are migrated to Modern Authentication. All newly created Microsoft 365 backup sets on Retrospect Virtual Console automatically use Modern Authentication.

Large number of Microsoft 365 users to Backup

It is recommended to divide the users into multiple backup sets. A single Microsoft 365 backup set should not contain more than 2,000 Microsoft 365 users. That is assuming that only small incremental daily changes will be made on the Run-on Client backup set.

By splitting up all the users into separate backup sets, the more backup sets, the faster the backup process can finish.

It is also a requirement that for every split backup set should have its own unique user account for authentication to minimize the probability of throttling from Microsoft.

Example: If there are 10 split backup sets, then there should be 10 unique user accounts for authentication.

Periodic Backup Schedule

The periodic backup schedule should be reviewed regularly to ensure that the interval is sufficient to handle the data volume on the machine. Over time, data usage pattern may change on a production server, e.g., the number of new files created the number of files which are updated/deleted, and new users may be added etc.

Consider the following key points to efficiently handle backup sets with periodic backup schedule.

  • Hardware – to achieve optimal performance, compatible hardware requirements is a must. Ensure you have the backup machine’s appropriate hardware specifications to accommodate frequency of backups,

    • so that the data is always backed up within the periodic backup interval

    • so that the backup frequency does not affect the performance of the production server

  • Network – make sure to have enough network bandwidth to accommodate the volume of data within the backup interval.

  • Retention Policy - also make sure to consider the retention policy settings and retention area storage management which can grow because of the changes in the backup data for each backup job.

Backup Source for Retrospect Virtual Host Server

For Microsoft 365 backup sets there are two approaches for backup source selection. Below are the sample screenshots of the selection All Microsoft 365 users and Selective Microsoft 365 user.

  • All Microsoft 365 users

If you select “Backup all Users”, all of the Microsoft 365 user accounts will automatically be selected.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image127.png

  • Selective Microsoft 365 user

If you select “Select Specific”, you can select the users that you want to backup.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image128.png

These are the Pros and Cons when selecting a backup source from all Microsoft 365 users and selective Microsoft 365 user.

All Microsoft 365 users

Selective Microsoft 365 user

Backup Set Maintenance

The Admin does not need to manage the backup set, e.g. to select or unselect user when a Microsoft 365 user account is added or removed, the changes are automatically updated in the backup source.

The Admin will have to select or unselect users manually when a Microsoft 365 user account is added or removed, as the changes are not automatically updated in the backup source this can be very time consuming.

If a Microsoft 365 user account is removed from the domain and the admin forgets to unselect the Microsoft 365 user account from the backup source, then this will cause a warning that the user does not exist.

Microsoft 365 License

The backup user account must have additional Microsoft 365 license modules assigned to cover any increase in Microsoft 365 users. Otherwise, if additional users are added without sufficient modules, then this will cause backup quota exceeded warning and additional users will not be backed up.

This will allow the admin to easily control or manage the number of license modules used for the backup set.

Backup Time

All Microsoft 365 user accounts will be backed up. This means the initial full backup job will take longer, any subsequent incremental backup will take longer.

Only selective Microsoft 365 user accounts will be backed up. This will mean the initial full backup job will be faster, any subsequent incremental backup will be faster.

Storage

As all Microsoft 365 user accounts are backed up, more storage will be required.

As only selective Microsoft 365 user accounts will be backed up, the backup set will require relatively less storage.

Data Synchronization Check

As all Microsoft 365 user accounts are selected for backup, regular DSC may not be required.

As only selective files and/or folders are selected for backup, DSC is highly recommended to synchronize de-selected files and/or folders in the backup source with the backup destination(s).

*All Items*

Tick all the checkboxes, all of the items of the Microsoft 365 user account will automatically be selected.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image129.png

Selective Items

Tick selective items to backup, either Outlook, OneDrive, Personal Site or Public Folders. In our example, only Outlook and OneDrive are ticked.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image130.png

These are the Pros and Cons when selecting a backup source from All Items and Selective Items.

All Items

Selective Items

User Maintenance

The Admin does not need to manage the backup set, e.g. to select or unselect items, the changes are automatically updated in the backup source

The Admin will have to select or unselect items manually as the changes are not automatically updated in the backup source.

Backup Time

All Items of the Microsoft 365 user account will be backed up. This means the initial full backup job will take longer, any subsequent incremental backup will take longer.

Only selective Items of the Microsoft 365 user account will be backed up. This will mean the initial full backup job will be faster, any subsequent incremental backup will be faster.

Storage

As all Items of the Microsoft 365 user account are backed up, more storage will be required.

As only selective items of the Microsoft 365 user account will be backed up, the backup set will require relatively less storage.

Creating a Microsoft 365 Backup Set

  1. Log in to the User Web Console.

  2. Click the User icon on the User Web Console landing page.

  3. On the Backup Set menu, click the + icon to create a backup set.

    https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image132.png

  5. On the same menu under Run on, select Server to create a Run on Server (Agentless) backup set.

Notes

  • If you choose to run the backup set on the Retrospect Virtual Console server, you won’t be able to back up, restore or manage your backups on Retrospect Virtual Host Server once the backup set is created.

  • This setting CANNOT be altered once the backup set is created. If you wish to change the backup method later, you will have to create a new backup set and start over the configurations again.

  • For backup sets created in Run on Server backup type, the backup destination is restricted to either Retrospect Virtual Console or a predefined destination (if setup by your backup admin). If you wish to back up to other cloud destinations or back up to multiple destinations, the backup set should be created in Run on Client backup type instead.

For Retrospect Virtual Host Server select the Backup scope and Region then click Test.

Overview of Microsoft 365 Backup Process

The following steps are performed during a backup job.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image187.png

Periodic Data Integrity Check (PDIC) Process

The PDIC will run on the first backup job that falls on the corresponding day of the week from Monday to Friday.

To minimize the impact of the potential load of large number of PDIC jobs running at the same time on the Retrospect Virtual Console server, the schedule of a PDIC job for each backup set is automatically determined by the result of the following formula:

*PDIC schedule* = %BackupSetID% modulo 5*

or

*%BackupSetID% mod 5

The calculated result will map to the corresponding day of the week (i.e., from Monday to Friday).

0

Monday

1

Tuesday

2

Wednesday

3

Thursday

4

Friday

NOTE: The PDIC schedule cannot be changed.

Example:

Backup set ID: 1594627447932

Calculation: 1594627447932 mod 5 = *2*

2

Wednesday

In this example:

  • the PDIC will run on the first backup job that falls on Wednesday; or

  • if there is no active backup job(s) running from Monday to Friday, then the PDIC will run on the next available backup job.

NOTE

Although according to the PDIC formula for determining the schedule is %BackupSetID% mod 5, this schedule only applies if the previous PDIC job was actually run more than 7 days prior.

Under certain conditions, the PDIC may not run strictly according to this formula. For example:

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image188.png

If backup jobs for a backup set are not run on a regular daily backup schedule (for example: on a weekly or monthly schedule), then the PDIC job will run if it detects that the previous PDIC job was run more than 7 days ago.

Backup Set Index Handling Process

To minimize the possibility of index related issues affecting backups, each time index files are downloaded from and uploaded to backup destination(s); the file size, last modified date, and checksum is verified to ensure index file integrity.

Start Backup Job

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image189.png

See above.

Completed Backup Job

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image190.png

See above.

Data Validation Check Process

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image191.png

As an additional measure to ensure that all files transferred to the backup destination(s) are received and saved correctly, both the number of 32 or 64 MB data block files and the size of each block file are checked again after the files are transferred.

Running Backup Job

  1. Log in to the User Web Console.

  2. Click on the User icon.

  3. Under the Backup Set > Manage Backup Set menu, you should see the backup set you have created.

    https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image194.png

    NOTE: Migrate Data will only be available if Deduplication is enabled for the backup set. Deduplication settings may be modified in Backup / Restore > User > Backup Set > %Backup Set Name% > Deduplication. When the Migrate Data option is enabled, the existing data will be migrated to the latest version during a backup job. Backup job(s) for backup sets with Migrate Data enabled may take longer to finish.

This option is disabled by default. When this option is enabled, the Data Integrity Check will perform check on the integrity of the files on the backup destination(s) against the checksum file generated at the time of the backup job.

If there is a discrepancy, this indicates that the files on the backup destination(s) are corrupted. These corrupted files will be removed from the backup destination(s). If these files still exist on the backup server on the next backup job, the Retrospect Virtual Console will upload the latest copy.

However, if the corrupted files are in the retention area, they will not be backed up again as the source file has already been deleted from the backup server.

Rebuild index

Microsoft 365 license usage in backup

The number of Microsoft 365 licenses used in a backup can be checked from the backup log. The logs will first display the number of licenses that can be used which is labeled as “Quota (E-mail Account)”. Then it will display the actual number of licenses used “Quota (E-mail account) used in this backup set”. Lastly, it will list the e-mail accounts that was used.

Here is a sample of how it is listed in the log:

[2022/06/15 11:53:58] [info] [-] Quota (E-mail Account): 400

Appendix D: Example Scenario for Backup Set Maintenance

Scenario: Microsoft 365 user account does not exist warning message

This is the sample warning message if the user does not exist. If a user is removed from the domain and the Admin did not manually unselected the user from the backup source, then during backup job there will be a warning that the user does not exist. The warning will appear on the backup log.

Backup job is completed with warning(s). Check the backup report for the warning message.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image306.png

Backup report contains a warning message.

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image308.png

Appendix E: Example Scenario for Data Synchronization Check (DSC) with sample backup reports

Selection of all folders vs selective folders

All folders selection

Selecting all folders automatically selects all the files and/or folders under Outlook, OneDrive and Personal Site of the selected Microsoft 365 user account. And all the files and/or folders under Teams, SharePoint Sites and Public Folders of the Microsoft 365 organization for Retrospect Virtual Host Server.

DSC is not required when all the folders are selected for back up. As during a backup job any deleted files in the backup source will be automatically moved to retention area.

Below are the sample screenshot of the backup source with all folders selected.

Retrospect Virtual Host Server

https://s3.amazonaws.com/download.retrospect.com/site/docs/virtual_microsoft_365_agentless_guide/image311.png

Selective folders

When not all folders are selected for backup and folders are subsequently un-selected from the backup source. The backup job will not pick up the changes of the de-selected folders, they will not be moved to the Retention Area but remain in the Data Area. In the long run this could result in a build-up of data in the backup destination.

DSC is highly recommended to synchronize de-selected folders in the backup source with the backup destination. This will ensure that there will be no data build up on the backup destination.

Below is the sample screenshot of the backup source with selective folders.
