-
Select RAC if you have selected a backup of a database in RAC environment.
-
Select Tablespaces if you want to restore only the tablespaces.

In the Recovery Scope page, select one of the following options:
-
Select Until SCN (System Change Number) if you want to recover to a specific SCN.
-
Select Date and Time if you want to recover to a specific date and time.

-
Monitor the restore process by using the Monitor > Jobs page.
Restore and recover pluggable database using point-in-time recovery
You can restore and recover a pluggable database (PDB) that has been corrupted or dropped without impacting the other PDBs in the container database (CDB). SnapCenter uses RMAN to perform point-in-time recovery (PITR) of the PDB.
-
In the left navigation pane, click Resources, and then select the appropriate plug-in from the list.
-
In the Resources page, select either Database or Resource Group from the View list.
-
Select the database of type single instance (multitenant).

Depending on whether you want to restore the PDB or tablespaces in a PDB, perform one of the actions:
-
Select Pluggable databases (PDBs) if you want to restore a PDB.
-
Select Pluggable database (PDB) tablespaces if you want to restore tablespaces in a PDB.
