bbarrish Posted August 21, 2002 Report Share Posted August 21, 2002 I reformated a drive this afternoon and did a backup of the drive before doing so. I recataloged the set, which resulted in the following message: + Executing Recatalog at 8/20/2002 4:09 PM To backup set Daily Backup 02… Bad backup set header found (0x66d6ffd6 at 7,492,133). Backup set format inconsistency (12 at 7492411) 8/20/2002 4:42:54 PM: 2 execution errors. Completed: 93239 files, 13.8 GB Performance: 418.5 MB/minute Duration: 00:33:31 I then proceeded to try and restore pieces and the drive just ended up hanging and when I viewed the log, I was presented with an exhasutive list of errors that all looked something like this: Backup set format inconsistency (7 at 5929336) When I tried to repair the backup set, Retrospect just states that the catalog portion appears to be valid and asks if I'm sure I want to rebuild the catalog. Am I out of luck or can this be repaired? It goes without saying that I have a lot of very important information that was backed up and I had never had a problem with the drive or any backups or restores in the past. I am using Retrospect Backup 5.0.205 under Mac OS X 10.2 (yes, it's the real thing that was packaged in a new Mac I just bought). The backup is stored on an external FireWire drive. Any help is most appreciated. Sincerely, Brad Link to comment Share on other sites More sharing options...
CallMeDave Posted August 21, 2002 Report Share Posted August 21, 2002 What sort of device did you back up to? Is there a SCSI card involved? Did you try a test restore before going ahead and wiping the drive? Dave (who would insist on two trusted backups before intentionally deleting data...)

bbarrish Posted August 21, 2002 Author Report Share Posted August 21, 2002 Dave, It's a FireWire drive, which I have never had problems with. Nothing SCSI about my system (G4/800 Power Mac). I run backups and have restored without error on many ocassions. I guess the good news is that I do keep two backup sets and the loss may end up being minor, but that's kind of beside the point. If lost, I could have very well lost a few chapters of a book, which would really be unfortunate, to say the least. Thanks, Brad Link to comment Share on other sites More sharing options...
CallMeDave Posted August 21, 2002 Report Share Posted August 21, 2002 In reply to: It's a FireWire drive... I'm still unsure of your setup. - Was this a File Backup Set stored on an external hard drive? - If so, why did you recatalog in the first place? - Exactly which Tool did you use for this operation?

shadowspawn Posted August 22, 2002 Report Share Posted August 22, 2002 I had a disturbingly similar problem, like you backing up to an external firewire drive, and only discovering issues (and Retrospect only reporting problems) after I had erased the original. In my case I lost all the affected data. Obviously a good rule of thumb is never to rely on a single backup. And a corollary as Dave mentioned, trying a restore of some sort is also a good sanity check before going for the erase. Next time...
