Infinite Disk is a hierarchical storage management (HSM) and backup utility for MS-DOS, Windows, and OS/2 published by Chili Pepper Software of Atlanta in 1992. [1] Infinite Disk introduced HSM, previously limited to mainframes, to personal computers. [2] [3] [4] A variant of Infinite Disk, Personal Archiver, was bundled with Iomega removable drives starting in November 1994. [5] The company and the software were acquired by Cheyenne Software in 1995, [6] which was in turn purchased by Computer Associates in 1996. [7]
Infinite Disk, operating in the background, automatically compresses less-active files and eventually migrates them to removable media, but the files remain visible in Windows folders and, when accessed, are fetched from the backup storage.
