Cloud Storage Providers

Additional Features

Proactive Backup

Need to protect laptops that come and go from the network? Retrospect’s Proactive Backup feature watches for computers and automatically backs them up when they connect to the network.

Data Deduplication

Retrospect maximizes storage usage by only copying unique files—even across multiple computers—to the backup media.

Flexible Destination

Retrospect can make use of multiple hard disk destinations, whether grouped together or used independently; connected directly via USB, FireWire, or eSATA; or when networked using Ethernet, iSCSI, or Fibre Channel. Retrospect supports most types of magnetic media for backup, including hard disk drives, network-attached disk, cloud storage, flash media, and every major tape format.

Fine-Grained Scheduling

Backup, copy, archive, and restore operations in Retrospect can be scheduled to meet any agenda.

End-to-End Encryption

Retrospect will optionally encrypt communications between network clients and the backup server using strong AES-256 encryption to prevent network snooping of private information. Now supports strong encryption for Windows and Mac clients. Retrospect provides multiple encryption options for safeguarding backup data against unwanted access, including government standard AES-256 encryption.

Powerful Filtering

To include or skip specific files, folders, and volumes, or to back up only specific data to cloud storage, Retrospect includes both built-in and user-definable selectors that filter data based on a multitude of conditions, including file names, dates, and types.

Power Conservation

To reduce the overall power demands for backups, Retrospect awakens sleeping/stand-by mode computers to back them up and then allows them to return to their low-power state.

Improved email reporting

Retrospect includes a wealth of data about your backups. The operations log is now included to give you complete insight into each backup's progress. Filter emails based on errors, warnings, or other keywords to hone in on issues as soon as they happen.

Easy Setup for Backup Strategies

Retrospect can transfer specific or all backups between Backup Set destinations, making it trivial to back up nightly to network-attached storage and then transfer just the most recent nightly backups to a portable hard disk for safe, offsite storage. Retrospect can stage backups to disk before transferring them to tape, ensuring that the fastest possible throughput is achieved at each stage. Disk-based backups can also be copied to tape for safe, offsite storage or archiving.

Additional Add-ons

Open File Backup Unlimited

This add-on makes it possible to protect line-of-business applications—such as accounting, CRM, and proprietary database systems—while they’re running, even those with data files spread across multiple volumes. Retrospect’s Open File Backup Unlimited add-on extends to all Windows systems protected by your Retrospect host server, including end-user desktops and laptops.
