The folks at Dantz Development, makers of the best-selling backup programs for the Macintosh, Retrospect and Retrospect Express, have released their first full version of Retrospect for Windows (previously Retrospect Clients for Windows were available, so you could use a Mac to backup Windows machines). Retrospect 5.0 for Windows comes in three versions: Retrospect Desktop Backup, Retrospect Workgroup Backup, and Retrospect Server Backup. The $150 Desktop version runs on Windows 95/98 and NT Workstation and backs up a single PC to all removable cartridge drives and most CD-R, CD-RW, and tape drives. The $300 Workgroup version also runs on NT Server and includes 20 Retrospect Client licenses to back up either networked Windows or Macintosh clients. Finally, the $500 Server version includes 100 Retrospect Client licenses and can back up client machines over multiple IP subnets. You can also download a 30-day 7.8 MB demo of Retrospect for Windows. The release marks Dantz Development’s first major move out of the Macintosh market, where Dantz already has about 95 percent of the market share. Ironically, according to Craig Isaacs of Dantz, the move was prompted by long-standing requests from Macintosh fans in Windows environments who were frustrated at the lack of decent Windows backup software.
