Retrospect is a family of backup software applications for the Mac OS, Mac OS X, and Microsoft Windows operating systems. Its maker Dantz Development Corporation was acquired by EMC Corporation in 2004. In May 2010 Retrospect was sold to Roxio/Sonic Solutions. In 2011, development of Retrospect was turned over to a privately held company operating under the name Retrospect, Inc. The first version from this company, Retrospect 9, was released on November 2, 2011.
The most common variants are:
Retrospect Express HD, supports backup to local and remote hard drives
Retrospect Express, adds support for removable media,
Retrospect, adds tape drives and network backup support. In the network backup scenario a backup host pulls data from multiple networked workstations.
Retrospect is both available for retail sale, and is often bundled with an external hard drive (though often the limited Retrospect Express version).
Retrospect Express was the successor to Dantz's DiskFit Direct backup product, which came bundled with Iomega's Zip 100 drive.
Retrospect was originally developed for the Macintosh and provided network backup support over Appletalk networks.
Retrospect has backup clients for Windows, Macintosh, Linux, Solaris, and NetWare.
