I got MRbackup 4.0b when it came out (some time ago), fiddled with it long enough to get the colors set the way I wanted them, and didn't mess with it again. Then yesterday, I get to thinking that I should back up my hard disk. the only backup utility I had around was MRbackup, so I decided to give it a whirl. It seemed to work very well. I checked the disks after the backup was complete, and noticed that a few .info files were missing. Odd, I thought, but not a problem. I used the Utilities tool to decompress a few of the archived files to RAM:, and they seemed okay. Then I made the bad boo-boo. Now that I had my backup, I decided that, since my drive was very badly fragmented, I would format/restore it to clean it up. I did this, and again, MRbackup seemed to work fine. I noticed that the drive had considerably less on it than it did before, though (down from 47% full to 40% full...). Everything seemed to be there, though, so I was a bit confused. I wandered about the disk, running the programs, until I started to run across file after file that was incorrectly restored. MRbackup had a bad copy of these files (in compressed form) on its backup set. All in all, I've found about 10 programs/data files that were munged (so far). Most are easily recoverable... Has anyone else found these bugs in this program? Has there been a subsequent release of MRbackup? I had been planning to send in the shareware fee if it worked well.

Yes, I got bitten really badly by this. A couple of weeks ago I lost
nearly all of about 10Mb of SHAM ILBM files after reformatting to fix a hard
disk problem. Previous versions of MRBackup worked reliably for me, but Mark
seems to have introduced a really nasty bug in this one.

I noticed this problem shortly after MRBackup v4.0b was released, and reported it to the author, Mr. Mark Rinfret. I posted a warning about this to this newsgroup some time ago. I am in the process of beta testing a new version of MRBackup which is claimed to fix the problem. -- Steven Litvintchouk MITRE Corporation Burlington Road Bedford, MA 01730 (617)271-7753 ARPA: sdl@mbunix.mitre.org UUCP: ...{att,decvax,genrad,necntc,ll-xn,philabs,utzoo}!linus!sdl "Where does he get those wonderful toys?"

I have been using it w/o compression, but find that I get a guru between the "Backup Completed" and "Idle" messages. It doesn't always happen, I've tried to nail the conditions where it does w/o success. Anyone in NTSC land have the problem, or is this some subtle PAL problem (others here using the same executable have the same problem, so it is not my particular configuration)?

[] 1. I did a restore from an old MRBackup archive and it worked fine - EXCEPT it GURUed upon completion. 2. During a Backup operation (or was it a Restore, I don't remember), the bytes output seemed to have two other fields over/underlaid on the field. I couldn't tell what these fields were, but they mixed in with the actual bytes output field on either end. This showed up after about 5 or 10 Meg of data had been processed. BTW, if there is a fixed version that reliably compresses and decompresses, please let me know. Thanks.
