DiskFit, from SuperMac (I think) -- probably the most intelligent backup program ever written. It's been described several times in this group so I won't bother doing it again. > How many disks do you think 60meg would take (I'll be backing up to floppy)? Well, I have about 32 meg on my Jasmine Direct Drive 80 and it takes around 42 diskettes. I thought I was through messing with diskettes when I got the hard disk! :-( So I guess the answer to your question is "a lot". By the way, you only have to feed all those diskettes in when you do a full backup of the disk. For an incremental backup, DiskFit just asks for a few of them (depending on what's changed on your disk -- it records deletions as well as additions and changes, so that your backup set is always current.) Also, DiskFit can also backup to tape cartridges, Bernoulli devices, or another hard disk. (I haven't tried any of these.) Hope this information helps! Kevin Dack kevin@trsvax.Tandy.COM

DiskFit is a reasonable hard disk backup program, but leaves a lot to be desired. >>How many disks do you think 60meg would take (I'll be backing up to floppy)? A formatted floppy has 785K and you probably won't get better than about 97% (761K) utilization. So, (60 * 1024) / 761 = 81 floppy disks. >By the way, you only have to feed all those diskettes in when you do a full >backup of the disk.

DiskFit often asks for more than a few disks, unless you backup very often. -- uucp: ...!seismo!cmucspt!me.ri.cmu.edu!dtw arpa: dtw@cs.cmu.edu
