For other uses, see Retrospect (disambiguation).

Retrospect is a family of software applications that back up computers running the macOS, Microsoft Windows, and Linux (and until 2019 classic Mac OS) operating systems. It uses the client–server backup model,[1] 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, a hard disk drive or cloud drive. The company's backup server application requires macOS or Windows, but versions of the client application can be run on Linux (or—until 2019—Classic Mac OS[2]).

The product is used for GUI-scripted[3] backup in "mixed-platform networks"[4], primarily by small and medium-sized businesses.[4][5]

History

The software was first developed by Dantz Development Corporation in 1989, initially for the Macintosh platform[6][7] and continuing later for Windows.[8] With sales split evenly between the two variants and the Macintosh variant claiming 90% of its market, Dantz Development Corporation was acquired by EMC Corporation in 2004.[9] In 2006 version 7.5, the refined first release of the Windows variant under EMC, added performance features needed by SMEs.[10] In 2009, EMC was working on[11] adding an updated user interface and separate administration Console similar to that of the newly released Macintosh variant version 8.0,[12] but mandatory Windows security settings starting with Windows Vista/Server 2008 subsequently forbade UI interaction with an application auto-launched[13] by a task.[2]

Meanwhile, the Macintosh variant had "languished"[12] at EMC—with temporary "end-of-lifing"[11], until "development was revived in 2008 when EMC hired back some of its former engineers"[9]—including ex-Dantz ones.[12] This resulted in the "premature"[5] release of a version 8.0 of Retrospect Macintosh that was temporarily[14] missing key operational features, even though it added the performance features of Retrospect Windows 7.5.[12]

In May 2010, the software was sold to Roxio/Sonic Solutions.[5] In 2011, following the purchase of Sonic Solutions by Rovi, development of the software was turned over to a privately held company.[9] Since 2012 Retrospect Inc. has continued to sell[15] two variants of backup server software that, while having nearly identical non-GUI code,[11] operate differently. Retrospect Windows substitutes a view-only Dashboard (which was upgraded in 2019 into a Web-based Management Console—with optional deployment of shared scripts[8]) for Retrospect Macintosh's separate Administration Console,[16] and basically keeps the pre-2009 terminology[note 1] and GUI .[1]

In June 2019 the holding company StorCentric—which also owns Drobo—announced that it had acquired Retrospect Inc.,[17] which it will operate as an independent subsidiary while integrating a version of the software with Drobo hardware.[11]

Small-group features

Backup destinations
Termed Media Sets[note 2]—allow media spanning and may contain one or more disks[12] (or, in the Windows variant, one or more superfloppies—termed "removable disks"[12]), one or more tapes or WORM tapes[18]—with barcode reading/tracking[12], one or more CD/DVD discs,[8] or a single AFP/SMB file[8] or Cloud storage account.[8] Except for older major versions[12] of the Desktop Edition,[16][note 3] the backup server is multithreaded so that multiple scripts can simultaneously back up to or restore from different Media Sets.[13]
Backups
Do versioning of files;[19] do client-side file-level deduplication;[3] can be incremental,[20] of subvolumes,[1][note 4] may specify files to be excluded or included (subject to deduplication),[19][note 5], may Archive data by deleting it from a source drive once it has been backed up.[21] Optional optimizations include data compression,[22] encrypting Media Sets and data transfers between a particular client computer and the server.[12] Moreover, volume-to-volume duplicates [note 6] of the latest versions of files in appropriate OS format can be made;[1] these—unlike backups—can be onto LTFS tapes.[23]
Data sources beyond the usual filesystems
Email accounts can be backed up—globally deduplicated[24]—and restored,[25] or directly migrated and synced,[26] for major services supporting IMAP.[8] Avid Media Composer devices are supported as sources for backup, copy/duplicate, archive, and restore scripts.[23]
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 scheduled "backup window".[12] Volume-to-volume duplicates in OS format of the latest versions of files can—going beyond what can be done via OS—also be verified.[1]
Proactive scripts
Are usually left running at times that are not in the scheduled "backup window", back up computers—frequently but not always mobile—transiently connecting to the network, determining backup priorities[3] by an "AI" algorithm that uses a decision tree supplemented by linear regression.[2] They are an alternative to another application's window-cramming tape-only "multiplexed backup" capability. As of 2019 Proactive scripts can use a Storage Group, which is automatically expanded as necessary with a Media Set for each source machine-volume, as a destination—enhancing opportunities for multithreading sources without manual administrator bookkeeping.[8]
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.[13] Monitoring with "Retrospect for iOS" is also available.[8]
Cloud Backup
Cloud Media Set type enables backup/restore/utility operations on data stored with AWS-S3-compatible cloud storage providers including Dropbox,[8] with Google Cloud Storage, and with Backblaze B2.[20] WebDAV is also available.[3]

Enterprise client-server features

Retrospect also supports several enterprise client-server backup features. These include:

Performance (especially of the backup server—which is now multithreaded in all Editions)
Disk-to-disk-to-tape capabilities[12] that may incorporate file exclusion,[13][note 5] creating synthetic full backups,[27] automated data grooming[27][28] with GDPR exclusion rules,[2][26] block-level incremental backup,[29] and "instant" scanning of non-APFS source volumes.[4][2]
Source file integrity
Backing up interactive applications, pausing/unpausing services via "script hooks".[23] Retrospect Virtual has the capability of backing up interactive applications via coordinated snapshots;[8] that separate product, with totally different code, is not discussed in this article.
User interface
Administration Console,[21] high-level/medium-term reports supplementing Administration Console,[21][25] e-mailing operations notifications to chosen recipients,[21] integration with monitoring systems via "script hooks,[21], and user-initiated backups and restores.[21]
LAN/WAN/Cloud
Advanced network client support[12]—which can be extended to "remote" clients anywhere on the Internet for Proactive scripts and user-initiated backups/restores,[2] and facilitating reconfiguration for cloud seeding and large-scale recovery.[30]

Editions and Add-Ons

Retrospect is sold with varying backup server capability levels, called "Editions", at non-expiring license–code prices[12] that cover one major version. The Edition is dictated[3] by the number of "server OS" computers being backed up; it in turn specifies a maximum number of client computers. The Desktop Edition can be used where only desktop or mobile computers (or Linux servers[16]) are being backed up, non-multithreaded in older major versions, to non-tape devices or to one non-autoloader tape drive. The Solo Edition "protects a single non-server computer and its external hard drives".[25]

"Add-Ons", which activate additional backup server features via Edition-linked license codes, may also be purchased:

Notes

  1. ^ The terminology was changed in the 2009 Macintosh variant; this article will use whichever variant's term seems more precise, with the other variant's term as a footnote.
  2. ^ Termed Backup Sets in the Windows variant; could have been referred to as archive files, except that Retrospect has long used the term Archive to refer to a backup operation that deletes data from a source drive once its backup is complete.
  3. ^ Activity threads are termed execution units in the Windows variant.
  4. ^ To be used, a Subvolume must be specifically defined to the Retrospect application as a name for a filesystem folder, and is therefore currently termed a Favorite Folder in the Macintosh variant.
  5. ^ a b Exclusion and/or inclusion is done with Selectors in the Windows variant; this misleading term has been changed to Rules in the Macintosh variant.
  6. ^ The Duplicate operation is currently termed Copy in the Macintosh variant.
