Recovery Manager with Remote Copy
Recovery Manager 3.0.3/3.0.4 for Oracle User’s Guide
Depending on the type (online, offline, datafile, or archive log) of the virtual copy's backup
image, corresponding database files are restored appropriately.
For and NBU (user-managed) restoration:
■
Control files are not restored by default.
■
For an online virtual copy, both datafiles and archive logs are restored unless individual
tablespaces or datafiles are being specified. In this case, only the corresponding datafiles
are restored.
■
Only datafiles are restored for an offline or datafile virtual copy.
■
Only archive logs are restored for an archive log virtual copy.
For an Oracle RMAN restoration:
■
Control files are not restored by default.
■
For an online virtual copy, only datafiles are restored. Archive logs are not restored to
minimize restore time as Oracle RMAN can restore only necessary archive logs during
recovery.
■
Only datafiles are restored for an offline or datafile virtual copy.
■
Restoring from an archive log virtual copy backup image is not supported as Oracle RMAN
can restore only necessary archive logs during recovery.
2.12 Recovery Manager with Remote Copy
If 3PAR Remote Copy is set up for a database, 3PAR Recovery Manager’s remote
synchronization utility (
vcdba_rsync
) can perform a periodic synchronization of database
virtual volumes. Once the synchronization process completes, a virtual copy is created
automatically for the remote virtual volumes on the secondary InServ Storage Server. The
virtual copy can then be mounted on a backup host for off-host processing purposes.
