Infinite Disk

Infinite Disk was an early hierarchical storage management (HSM) and backup utility for DOS, Microsoft 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]

The company and the software were acquired by Cheyenne Software in 1995,^[5] which was in turn purchased by Computer Associates in 1996.^[6]

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.

A variant of Infinite Disk, Personal Archiver, was bundled with Iomega removable drives starting in November 1994.^[7]
