The Exchange Agent snapshot fails.
You run a migrated or new snapshot backup for data
on Exchange 2000 Server or 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
Check Process logical volumes for offhost backup

Disk-based Backup Option.
