Note the following when you perform snapshot backup or restore operations:
If you want to restore a snapshot backup from a multiplexed tape, restore the entire storage group. If you attempt to restore a single database from a storage group that contains multiple databases, the restore may fail. This issue will be fixed in a future release.
If you want to restore from a snapshot image, the
restore fails if an Exxrestore.env
file exists in the transaction log folder for the database or the
storage group. This temporary Exchange file can be left from a
previously failed restore. A Windows application event log entry
from Exchange tells you that this file is the problem. Remove this
file manually before you attempt another restore.
When you launch an Exchange off-host backup from the Backup, Archive, and Restore interface or from a node in a DAG, the progress log window does not display the usual progress messages as when a scheduled backup is executed. This lack of progress logging does not affect the backup operation. If you want detailed progress, use the NetBackup Administration Console to launch a manual backup operation of the Exchange policy.
