FastBack

FastBack 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. 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. When combined with compression techniques and a proprietary disk format that stored 720KB of data on each 360KB 5¼-inch floppy disk (only in 1.2MB drives), this made FastBack one of the fastest PC backup programs at the time.
