I've used MRBACKUP and found that I can live with it's speed by using it to backup to aome sort of a "fake floppy" --- either a RAD: configured to be congruent with a real floppy, or a fake floppy on a hard drive. Then, after each fake floppy is "filled", use diskcopy to create the actual backup disk (in another task --- remember, the Amiga CAN multitask 8-) ). I don't bother with compression, and kinda like the warm feeling in my tummy, knowing that all my data is stored in nice standard AmigaDos format that can be read on ANY system! I don't even need to fool with MRBACKUP to restore... Just diskcopy the floppy to RAD:, copy RAD: to the HD, reformat rad: (with the quick option) and prompt for another floppy. When I changed disk drives to the one I now have on my BBS, I used this method to restore about 140 floppies. It would take about 50 seconds to restore a floppy to a clean partition, and about 70 seconds by the time a 110 meg partition was over 100 megs full. Your mileage, of course, may vary. --- Cal // Cal Jones - Internet: <Jones@UV4.Eglin.AF.Mil> \X/ BBS: 904-243-6219 1200-9600HST 340Meg, all Amiga Single Tasking? *JUST SAY NO!!!*

I agree that it's nice knowing that your files are in AmigaDOS format, _but_ when you use compression, they are still in AmigaDOS format, each file being individually compressed. For a complete restore, the compression is a pain, but you doen't need MRBACKUP to restore them in any event. The "compress/decompress" program (the port of the Unix one) works fine (yes, the files are stored as .Z files). Just wanted to clarify that for people who aren't familiar with MRBACKUP. I feel that the combo or compression and standard AmigaDOS format makes this the most "robust" program. I don't feel safe having my backups in someones neato-keen-custom-format on floppy. -- -- Blair MacIntyre, Professional Leech on Society ( aka CS Graduate Student ) -- bmacintyre@{watcgl, watdragon, violet}.{waterloo.edu, UWaterloo.ca} -- Date, verb: prearranged socializing with intent.

Although it does not use Amiga Dos format it makes up for it with speed and relyability. It takes just over 30 minutes to back up 25Megs onto *UNFORMATED* floppies. It uses its own format, but i store a backup of it with my HD backup disks so I always have it handy if I need to restore something, and I have had to about 4 times since I started using it. Restores are just as fast, and you can restore individual files or the whole drive and have option to put the files in the same place , a different place, and whethor on not to restore the full subdirectory structure. -Todd 871579l@aucs
