 Exchange 2003 Intermittent Backup Trouble NTBackup
Exchange 2003, Exchange Backup, NTBackup
First off, thanks heaps. I've been seeing an intermittent failure of my Exchange 2k3 box to successfully complete its full backup job with the following Event error: The backup has stopped with error -521 and, in the backup log, "First Storage Group is not a valid drive or you do not have access". I'm only backing up Exchange data using NT Backup, no virus app is currently installed (only while t/s)and I'm logging in as the domain admin for this one. The backup job seems to fail anytime from 10 minutes after start to 2+ hours into it with no apparent rhyme or reason.... Any help or tips would be most appreciated. Its growing very old babysitting what once was a perfectly performing scheduled job.....sigh. Thanks heaps, y

I have EX23 and Ntbackup. HAd problems initially.
U may want to do an offline integrity check and defrag. Tidy up the DB. But see if u can do it on a test server first so u don’t corrupt the DB!

Next make sure u separate the EXDB backup from the windows system state. I still have some issues with the system state not backing up and have to run that manually in the mornings sometimes. I also backup the BKF to disk first which is later pulled to tape as part of the nightly tape backups.
