In general NetVault specifies that an Oracle database must be OPEN to be backed up by NetVault using RMAN. However, it is possible to backup a database that is in MOUNT mode.
For a GUI backup, the backup selection set or job must already be defined, and must NOT include the whole database node, the tablespaces and other selection items must be selected individually.
If the entire database node is selected, the backup process tries to connect to the database in order to browse the tablespace list, which will only work if the database is OPEN.
Once a job or selection set has been defined while the database is OPEN, it can be subsequently used when the database is in MOUNT mode.
It is possible to run a backup of a database in MOUNT mode using the RMAN CLI, for example:
allocate channel c1 type 'SBT_TAPE';
release channel c1;
Both these methods will only work if all the normal RMAN/Netvault configuration requirements have been met.
