Dantz sold some other backup software at the same time as Retrospect 2.0, which was more oriented toward the single user. It was something like FileSafe, or maybe it had the word Disk in the name. However, it may have been designed to copy to a big pile of floppy disks. I can't remember any more.

We probably ought to (in all that spare time we have) start an encyclopedia of old Mac software, sort of like Version Tracker ought to be, going all the way back through the old versions.

Wikipedia to the rescue. DiskFit. If you can find an old version of DiskFit, that might do what you want.

Dawbllaaaa. The Wikipedia entry for Retrospect is pathetic. I could swear that it used to be better. Do companies edit their own entries to remove useful information?

The second paragraph here contains some useful information:
