Does anyone know of any Hard Disk backup software? I have a 20 meg hard disk, and my backup solution consists of using Copy ALL to copy each directory onto its own floppy. This takes me about 2 hours. If this was automated, it would be real nice. Another thing to take into consideration for backup software is whether it changes the file date or not. Consider a directory with a lot of file.c and file.o. Well, the Copy command sets the date of the resulting file to the current date. Since it copies stuff in no particular order, often times the file.o's date can be earlier by a few seconds then the file.c. This means that if you use "make" you are going to have to recompile for no reason. So backup software (if any exists) that retains the original date would be nice. Of course, if you know of pd stuff thats great; but pointers on commercial products are ok, too. By the way, I have written a review of the MicroBotics MAS-20 hard disk. I haven't posted it yet, as the review is 250 lines long, and I have a suspicion that most readers don't read beyond the first screen :-). However, if there is any interest, I will be happy to post the review. My trademarked one last point. I have received many notes from people replying to my query of whehter a Lock() returned a &FileLock. The answer is that it does, but it's a BPTR.

The easiest thing to do is get a hold of the PD tar, PD compress, and the PD PIPE: device. You simply set up a script which TAR's the harddisk's root directory PIPE'd through compress with compress's output going to a floppy. If you have a lot on your hard disk, you would have to do several TAR's on it's subdirectories rather than a single TAR from root, each going to a different floppy. I use this method backing up my floppies... I get about 800K -> 200K (backing up mostly text). Did I say easiest? -Matt

It is a quick and dirty port, but it is usable. >each directory onto its own floppy. This takes me about 2 hours. If ^^^^^^^^^^^^^ Gak!

The alpha version does not preserve the date. The beta versions will, using the new facilities available under 1.2 Beta 1 will be ready in the next week or so. > Of course, if you know of pd stuff thats great; The alpha version is not pd, but it is freely redistributable. All subsequent versions, up to and including any possible commercial release, will not be. Disclaimer: I am the author of bru so I obviously have some interest in seeing it become popular. -Fred -- =========================================================================== Fred Fish Motorola Computer Division, 3013 S 52nd St, Tempe, Az 85282 USA {seismo!noao!mcdsun,hplabs!well}!fnf (602) 438-5976 ===========================================================================
