Retrospect is a family of software applications that back up computers running the macOS, Microsoft Windows, Linux, and classic Mac OS operating systems. It uses the client-server backup model, which means there must be a backup server application running on one computer and small-footprint client applications running on the other computers being backed up in either a single platform or mixed platform network. The destination may be a tape drive instead of a hard disk drive or cloud drive. The company's backup server application runs on either a macOS or a Windows computer, but there are also versions of the client application that run on Linux or classic Mac OS.
The product is used for GUI-scripted backup in a heterogeneous network, primarily by small and medium-sized businesses.

History
The software was first developed by Dantz Development Corporation in the mid-1980s, initially for the Macintosh platform and later for Windows. Dantz Development Corporation was acquired by EMC Corporation in 2004. Version 7.5, the first release of the Windows variant under EMC, added features needed by SMEs. In 2009, EMC indicated an intention to add an updated user interface and separate administration console similar to that of the newly-released Macintosh variant version, but mandatory Windows security settings starting with Windows Vista/Server 2008 subsequently prevented it.
Meanwhile the Macintosh variant languished at EMC, until "development was revived in 2008 when EMC hired back some of its former engineers". This resulted in the "premature" release of a version of Retrospect Macintosh that was missing former features.
In May 2010, the software was sold to Roxio/Sonic Solutions. In 2011, following the purchase of Sonic Solutions by Rovi, development of the software was turned over to a privately held company. Since 2012 Retrospect Inc. has continued to sell two variants of backup server software that, while having nearly identical non-GUI code, operate differently--with a view-only Dashboard substituting for a separate administration console in Retrospect Windows.

Small-group features
- Backup destinations
- Called Media Sets (Backup Sets in the Windows variant)--allow media spanning and may contain one or more disks, in the Windows variant one or more superfloppies, one or more tapes or WORM tapes, one or more CD/DVD discs, or a single AFP/SMB file or Cloud storage account. If run using a non-Desktop Edition, the backup server is multithreaded so that multiple scripts can simultaneously back up to or restore from different Media Sets.
- Backups
- Always versioned; do client-side file-level deduplication; can be incremental, of subvolumes, exclude files; optional optimizations include data compression, encryption of Media Sets and of data transfers between a particular client computer and the server.
- Avid production tool support
- Supported as sources for backup, copy/duplicate, archive, and restore scripts.
- Validation of backups and copies of backups
- Comparing byte-by-byte or via MD5 digest; using saved MD5, can be a separate verification script run outside the network's "backup window".
- Proactive scripts
- Are usually left running at times that are not in the network's "backup window", back up computers--frequently but not always mobile--transiently connecting to the network in the sequence of their least-recent time of previous backup.
- Success validation
- With e-mailing of notifications about operations to chosen recipients; for Backup runs these are now customized to include a one-line summary at the top, a subject line that includes the script name and number of errors and warnings, and an e-mail body that consists of the script log--pinpointing the errors and warnings. Monitoring with "Retrospect for iOS" is also available.
- Cloud Backup
- Cloud Media Set type enables backup/restore/utility operations on data stored with AWS-S3-compatible cloud storage providers including Dropbox, with Google Cloud Storage, and with Backblaze B2. WebDAV is also available.
Enterprise client-server features
Retrospect also supports several enterprise client-server backup features. These include:
- Performance
- Disk-to-disk-to-tape capabilities, creating synthetic full backups; automated data grooming, block-level incremental backup, and "instant" scanning of client volumes.
- Source file integrity
- Backing up interactive applications with pausing/unpausing of services via "script hooks".
- User interface
- Administration Console, user-initiated backups and restores, high-level/long-term reports supplementing the Administration Console, and integration with monitoring systems via "script hooks".
- LAN/WAN/Cloud
- Advanced network client support and cloud seeding and large-scale recovery.
Editions and Add-Ons
Retrospect is sold at a variety of capability levels, termed Editions, with backup server features specified through the purchase of license codes. The backup server Edition is dictated and priced by the number of "server OS" computers being backed up. The less-expensive Desktop Edition can be used where only desktop or mobile computers (or Linux servers) are being backed up, non-multithreaded, to non-tape devices or to one non-autoloader tape drive.
"Add-Ons", which activate additional backup server features via license codes, may also be purchased:
- backing up Microsoft Exchange servers or Microsoft SQL servers
- non-Desktop-Edition protection of open NTFS files, such as for continuously-running QuickBooks, on Windows systems
- backing up to multiple single tape drives simultaneously or to a multiple-drive tape library
- extending the bare-metal Emergency Recovery CD to adjust Windows boot volume drivers
- backing up and restoring more client computers than the maximum the chosen Edition specifies
