Symantec Backup Exec

An Exchange Agent snapshot job fails on the following conditions:

• The Exchange Agent snapshot fails.

• You run a migrated or new snapshot backup for data on Exchange Server 2003 on Windows 2000. Snapshot backups of Exchange are only supported for Exchange Server 2003 or later on Windows Server 2003 or later. The job does not fall back to a non-snapshot backup because Exchange snapshot and non-snapshot backups are not interoperable.

  The snapshot backup continues for resources that are supported, and the job can successfully complete with exceptions.

  To allow the snapshot to continue for the supported resources, do one of the following:

  • Check Process logical volumes for backup one at a time on the Backup Job Properties for the Advanced Open File Option.

  • Check Process logical volumes for offhost backup one at a time on the Backup Job Properties for the Advanced Disk-based Backup Option.

• If incremental or differential backup methods are selected, and Exchange Server 2003 Service Pack 1 or later is not installed.

• If circular logging is enabled, and incremental or differential backup methods are selected.

• You run a snapshot job on Windows Small Business Server 2003. The Microsoft Exchange Server 2003 VSS Writer is disabled on Windows Small Business Server 2003, which causes snapshot backups for Exchange 2003 to fail.
