Intermittent status 23 errors for MS SQL backup
I have a Windows client running MS SQL that is experiencing intermittent status 23 errors. The file system backup for this client is working without issue, the problem is only with the SQL backups. There are two databases that are being backed up, and some days both back up fine, other days one or both fail with the status 23 error. This environment is as follows:
Master: Windows Server 2003 R2 Enterprise Ed SP2 running NBU Server 7.0
Client: Windows Server 2003 R2 Enterprise Ed SP2 running NBU 7.0 client and MS SQL Server 2000.
What logs should I enable (dbclient? others?), and else what should I look at to resolve this problem?
