Hi Dan, I don't know what you have tried already, but if you are repeatedly getting catalog out of sync errors, that may be a sign of SCSI problems, corruption on the volume on which the catalog is stored, or, as you alluded to, crashes during the backup. If you haven't already, take a look at Tech Note 406 on our website. This discusses missing EOD (end of data) markers, which can have an effect on the catalog as well: http://www.dantz.com/index.php3?SCREEN=technotes Typically, you'll get an out of sync catalog if the backup crashes before the catalog is updated to reflect the data that was copied in that session. To address it, start by rebuilding the catalog from scratch to a different location on your hard drive. It may be helpful to break the backup down into smaller volumes, as Retrospect updates the catalog after completing each volume; therefore if you have to update, it will be easier. Continue your backups (you may want to add a script to duplicate the catalog file after the backup operation completes so you have working copies of the catalog that you can revert to if this one has problems). If the problems seems to persist, even in sessions during which the server doesn't crash, you may need to investigate the possibility that SCSI problems are causing corruption in the copied data. For continuing problems, please give us a call so we can get specifics on your configuration.
