Office 365 Guide

Requirements and Recommendations

Hardware and Software Requirement

Refer to the following link for details of the operating systems, applications and databases supported by Retrospect Virtual Host Server.

Overview

Retrospect Virtual provides a set of tools to protect your Office 365 user accounts. This includes backup and recovery of individual emails, contacts, calendars and other mail items in your Office 365 Outlook, files on OneDrive and SharePoint, with snapshots / versioning, and retention policy to protect even items that you may have accidentally deleted from your Office 365 user account.

You can protect Office 365 via an agentless backup on the Retrospect Virtual Console or on the Retrospect Virtual Host Server.

Selectable Backup Run Type

You can choose to either run the backup set you created on Server (Retrospect Virtual Console) or Client (Retrospect Virtual Host Server).

Run on Server

A Run on Server Office 365 backup set provides you with an agentless backup solution. Manual or scheduled backup job is performed on the backup server (i.e. Retrospect Virtual Console); you do not need to install a backup agent on your personal computer in order to backup your data on cloud storages. The advantages of agentless backup technology make it a good option for users who want to simplify the backup and restore management.

Run on Client

A Run on Client Office 365 backup set provides you with an agent-based backup solution. Manual or scheduled backup job is performed on the client computer (i.e. Retrospect Virtual Host Server); you need to install a backup agent on your personal computer in order to back up your data on cloud storages. The advantages of agent-based backup technology make it a good option for users who want to have more control on individual backup / restore and resources management.

Comparison between Run on Server and Run on Client

With both Run on Server (agentless) and Run on Client (agent-based) backup options available and the freedom to use different setting on different backup sets according to your needs, our backup solution offers you with high level of flexibility and efficiency for Office 365 backup and restore.

Below is the comparison between backup and restore job Run on Server and Run on Client.

Run on Server / Retrospect Virtual Console

Installation

No need to install the client backup agent on your computer or upgrade it when a newer version becomes available, which can fulfill some regulatory requirements of compliance during backup or restore.
Only a web browser and internet connection are needed.

Backup * Backup operation of all users are performed on the backup server, which means multiple jobs may run at the same time leading to slower performance. * Backup period will be shorter as the backup data are transferred directly from Office 365 to Retrospect Virtual Console backup server. * Backup destination is restricted to Retrospect Virtual Console backup server.

Large Number of User Backup Sets

Backup of large number of user backup set may take more time. As it will increase the Retrospect Virtual Console server load a lot if run multiple user backup sets concurrently and may affect the server performance, so it will make backup speed slower and period longer.

Cost

Do not require provision of additional Windows machine.

Restore

Restore operation of all users are performed on the backup server which may have multiple jobs to run at the same time, resulting in slower performance.
Restore period should be shorter as the backed-up items are transferred directly from Retrospect Virtual Console backup server to Office 365.

Run on Client / Retrospect Virtual Host Server

Installation

Need to install the latest version of Retrospect Virtual Host Server on computer with internet access for connection to Office 365 account.

Backup

Backup job is performed on your computer with resources that is dedicated to yourself.
In the event of a failure to a single backup agent, it fails in isolation to other users’ environment.
Backup period will be longer as the backup data are transferred from Office 365 to Retrospect Virtual Host Server, then to Retrospect Virtual Console backup server.
Backup destination can be Retrospect Virtual Console backup server, local and cloud drive and FTP.

Large Number of User Backup Sets

Backup of large number of user backup sets may take less time. As backup sets can be run concurrently over several machines as distributed solution, the resource will be more and will make backup speed faster and period shorter.

Cost

May require the provision of an additional Windows machine.

Restore

Restore job is performed on your computer with resources that is dedicated to yourself.
In the event of a failure to a single backup agent, it fails in isolation to other users’ environment.
Restore period should be longer as the backed-up items are transferred from Retrospect Virtual Console backup server to Retrospect Virtual Host Server first and then to Office 365.

Fast and Efficient

Retrospect Virtual Host Server 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 Office 365 backup sets supports

Backup of 4 users concurrently (4 threads).
For each of the 4 users, now supports a maximum 4 items concurrently (4 threads).

Index File Structure – The index file structure has been re-designed to improve the backup and restore performance.

Each Office 365 user will have its own individual index file instead of a single index file for all users within the backup set.

This new design eliminates any potential I/O performance bottlenecks when the index files are updated during each backup job, which can occur when using single index file structure for multi-thread concurrent backup.

Block Level Incremental Backup – this technology breaks down the backup files into multiple blocks and only the changed blocks will be backed up each time.

Backup of Selected Items

To back up the Office 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 contents or just one item.
- Restore items to the original location or an alternate location.

High Level of Security

We understand your Office 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.

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

Centralized Management Console

Our enriched features on the centralized web console offers you a one-stop location for monitoring and managing your backup and restore. Below is an overview of what you can do with it.

Create/ update/ delete backup set
Restore backup set
Configure user settings
Configure backup settings
View and download backup and restore reports
Monitor backup and restore live activities
Monitor storage statistic

Cloud Destinations Backup

To offer you with the highest flexibility of backup destination, you can now back up Office 365 user to a wide range of cloud storage destinations. Utilizing cloud destination backup gives you an extra layer of protection in the event of a local drive corruption, where you will still be able to retrieve data from the cloud destination.

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 corrupted, it will only affect corresponding user, while other users selected for backup are unaffected.

Preparing for Backup and Restore

Other Requirements

Add-on Module Requirement: One Office 365 Backup license is required for the backup of each user. No license is required for public folder. Make sure that the Office 365 Backup feature has been enabled as an add-on module in your Retrospect Virtual Host Server user account and there is sufficient Office 365 Backup license quota to cover the backup of your users.
Access for Retrospect Virtual Console User Web Console: It is now possible to perform agentless backup and restore, which can be done via the Retrospect Virtual Console User Web Console without using the Retrospect Virtual Host Server client agent. In order to access the User Web Console, make sure you have Internet connection and a web browser installed on your computer or mobile device.
Retrospect Virtual Host Server Licenses: Retrospect Virtual Host Server licenses are calculated on a per device basis:
- To backup users with 1 backup client computer (e.g. 1 Retrospect Virtual Host Server installed), 1 Retrospect Virtual Host Server license is required.
- To backup users with multiple backup client computers, the number of Retrospect Virtual Host Server licenses required is equal to the number of devices. For example, if there are 10 users to be backup with 3 backup client computers, then 3 Retrospect Virtual Host Server licenses are required.
Backup Quota Requirement: Make sure that your Retrospect Virtual Host Server user account has sufficient quota assigned to accommodate the storage of the Office 365 users for the new backup set and retention policy.
Java Heap Size: The default Java heap size setting for Retrospect Virtual Host Server is 2048 MB / 2.048 GB. To avoid any inconveniences and ensure smooth operation when performing Office 365 backup, it is highly recommended to allot extra memory.

Below is the table for the memory requirement:

OneDrive Account

100 MB

Site Collection / Personal Site

150 MB

Note: The memory requirement is dependent on the number of OneDrive or Site Collections/Personal Sites selected for backup.

These are some examples for better appreciation with formula for calculating the required memory:

Example 1: Backup set with 20 Personal Sites and 50 OneDrive Accounts

Personal Sites – 20 x 150MB = 3000 MB / 3 GB OneDrive Accounts – 50 x 100MB = 5000 MB / 5 GB

Total = 3000 MB / 3 GB + 5000 MB / 5 GB = 8000 MB / 8 GB

In this example, we first computed for the memory needed for the Personal Sites and OneDrive Accounts which are 3000 MB / 3 GB and 5000 MB / 5 GB respectively. Then we added those two and came up with 8000 MB / 8 GB. This is the total Java heap size setting of the Retrospect Virtual Host Server client should set.

The Java heap size to be configured should not exceed 2/3 of the RAM available, to allow sufficient resources for the operating system.
Granting Permission to Accounts for Creating Backup Set

Before the Office 365 account administrator or other accounts can create a backup set, the administrator has to grant permission to the account(s) which are going to create backup set. The account must be a member of the following security groups:

Limitation

For backup and restoration of Office 365 backup set, there is some limitation.

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 of 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.
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 of the original folder(s).

Example: Item from Outlook of User-A and User-B will be restored to the Outlook of the alternate location User-C.
Only administrator account or user account with administrative authority can restore backup items to an alternate location.
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.
If you are trying to restore the item to a destination user which has a different language setting than the original user, Retrospect Virtual Host Server will restore item(s) to their respective destination folder based on the translation listed below.

For folders such as ‘Calendar’ or ‘Notes’, a new folder ‘Calendar’ or ‘Notes’ will be created.

For folders in OneDrive and SharePoint, a new folder will be created.

Best Practices and Recommendations

The following are some best practices or recommendations we strongly recommend you to follow before you start any Office 365 backup and restore.

Temporary Directory Folder Location (For backup and restore running on Retrospect Virtual Host Server only): Temporary directory folder is used by Retrospect Virtual Host Server for storing backup set index files and any incremental or differential backup files generated during a backup job. To ensure optimal backup/restoration performance, it is recommended that the temporary directory folder is set to a local drive with sufficient free disk space.
Performance Recommendations: Consider the following best practices for optimized performance of the backup operations:
- Enable schedule backup jobs when system activity is low to achieve the best possible performance.
- 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.
Set Backup Destination: After creating the backup set-in Run-on Client mode on Retrospect Virtual Console user web console, please remember to login Retrospect Virtual Host Server to set the backup destination if you want the backup destination to be Local/ Mapped Drive/ Removable Drive.
Backup Destination: To provide maximum data protection and flexible restore options for agent-based backup, it is recommended to configure:
- At least one offsite or cloud destination
- At least one local destination for fast recovery
Login Retrospect Virtual Host Server: After modifying the backup schedule setting or Continuous Backup setting of the Run on Client backup set on Retrospect Virtual Console user web console, please remember to login to the Retrospect Virtual Host Server client once to synchronize the changes immediately.

Large amount of Users to Backup: It is recommended to divide the users into multiple backup sets. By default, the Office 365 backup module can back up a maximum of 4 users concurrently (4 concurrent backup threads), while backing up a maximum of 4 items concurrently per user (4 concurrent backup threads). Therefore, each backup set supports a maximum of 4x4=16 backup threads at a time. By splitting up all users into separate backup sets, the more backup sets, the faster the backup process can achieve.

Example-1: There are 100 users needed to be backup, you can divide 20 users into one backup set.

Backup Set Name	User Number
Backup -Set-1	No.1 — 20
Backup -Set-2	No.21 — 40
Backup -Set-3	No.41 — 60
Backup -Set-4	No.61 — 80
Backup -Set-5	No.81 — 100
