Normal backup erased prior sessions!

[sbleono]

HI. I'm running Retrospect Desktop 6.1.126 on OS X 10.4.7. I have a weekly backup routine that involves 2 external HDs. I switch drives on Friday and do a scheduled recycle backup Saturday at 12am. Then I do scheduled normal backups each night until I switch drives again.

 

I happened to notice that my backup file on the current drive was much smaller than it normally is. It should be ~10GB, but it's only 1.35GB. To find out what was going on, I moved my backup set catalogue out of the way and rebuilt it from the backup file. The rebuilt catalogue only contains sessions from the last two nights (Monday and Tuesday), even though they were both Normal Backups, and I'd done a Recycle followed by two Normal Backups to the same backup set prior to them!

 

So, it appear that Monday night's Normal Backup erased the contents of my backup set before it ran, but it retained the catalogue information from the prior backups, since it only backed up changed and new files (hence the smaller than normal size). This is a serious case of silent data loss, and I really hope that someone has some insight into what might've happened, because this really freaks me right out.

 

The catalogue browser reports the following sessions in the set:

elisa Elisa 207 files 10/4/2006 12:12:32 AM

Users root 579 files 10/4/2006 12:00:22 AM

Users root 646 files 10/3/2006 12:00:23 AM

 

Here's the relevant part of my log. I've omitted the Recycle and the first Normal to save some space.
