museum_guy Posted January 3, 2008 Report Share Posted January 3, 2008 Every three or four days, the Exchange Mailboxes backup set (which is set up as a disk, backing up to a Xserve Raid) reports status as "media." When I try to repair the backup set, it tells me the set is damaged beyond repair. The backup set has to be recreated when this occurs. It is the only backup set that exhibits this problem. We are using Multi Server version 7.5.387 Any help would be appreciated. I have read through the manual; if I have missed anything obvious please point me to it.

Mayoff Posted January 3, 2008 Report Share Posted January 3, 2008 How big is the backup set? How many total files? How many sessions? Quote Link to comment Share on other sites More sharing options...
museum_guy Posted January 3, 2008 Author Report Share Posted January 3, 2008 The size of the backup is 26.54 GB. There are about 300 sessions. Roughly 750,000 files Quote Link to comment Share on other sites More sharing options...
Mayoff Posted January 3, 2008 Report Share Posted January 3, 2008 Are you using grooming? What disk is the catalog file saved to? Quote Link to comment Share on other sites More sharing options...

Mayoff Posted January 3, 2008 Report Share Posted January 3, 2008 Because you use grooming, I would follow these guidelines: http://kb.dantz.com/article.asp?article=9629&p=2 Quote Link to comment Share on other sites More sharing options...
museum_guy Posted January 4, 2008 Author Report Share Posted January 4, 2008 We will try these and let you know how it works. As I said it fails after 3 or 4 days so it might be next week before we see results. Quote Link to comment Share on other sites More sharing options...
museum_guy Posted January 10, 2008 Author Report Share Posted January 10, 2008 So far things seem to have worked for us. From the list you provided it was item 2 that seems to have fixed things for us. Here it is below: 2) Keep your catalog files saved to a local disk (like C:\) instead of a network volume. Do not save the catalog file to the same disk as your backup data files (.rdb files). Quote Link to comment Share on other sites More sharing options...
