Consider the following before restoring Oracle data from the backup system:
• Free space equivalent to twice the size of the backup is required on the Unitrends appliance for restore processing. If adequate space is not available, the restore will fail.
• Restores are performed to the original database only. If you are replicating and the original database is not available, you can restore from the target after performing a bare metal restore of the Oracle client. See Oracle for Windows restore from the replication target for details.
• Only one restore or backup operation per database can run at any given time.
• For a given database, any backups initiated while a restore is in progress will fail. Once the restore completes, backups can be run for the given database.
• For a given database, any restores initiated while a backup is in progress will fail. Once the backup completes, restores can be run for the given database.
• For item-level restores, the backup is unfolded to a Unitrends appliance. From here you can restore items using an Oracle or third-party tool. When you are finished restoring, you must tear down the share (See To view or tear down Oracle restore images). Subsequent backup or restore operations for the given instance will fail until the restore share has been torn down.
• For Oracle on Windows, restore requires that the underlying filesystem has the same structure as when the database was initially backed up. For details, see KB 1563.
