FastBack[1] is a software application developed in the late 1980s and early 1990s for backing up IBM PC and Macintosh computers.

It was originally written by Fifth Generation Systems, a company located in Baton Rouge, Louisiana.

[2] When the company wanted to expand into the Apple market they purchased and rebranded a product from TouchStone Software Corporation.

The original FastBack was unique in the industry in that it was able to read from a computer hard drive and write to the floppy drive simultaneously using the full capability of the dual-channel DMA chip found in personal computers of that time.

The New York Times wrote about the standard DOS (MSBACKUP) utility, that it "cannot automatically awaken itself at 3 A.M. to make a full backup onto a quarter-inch cassette drive.
