Backup and Restore Limitations

The following are limitations for backups and restores initiated with the option:

The online redo logs are exclusively locked by Oracle while the Oracle database is online. Perform an offline backup if necessary.
To restore either the system tablespace or a tablespace containing rollback segments, you must first shut down the database and perform a full database restore. For more information, see the section Restore the System Tablespace in this chapter.
If you back up the Oracle database using the Arcserve Backup interface, you must restore it using the Arcserve Backup interface. Similarly, if you back up the Oracle database using RMAN, you must restore it using RMAN.
The Agent for Oracle in File-based mode does not support backup and restore processes on raw devices and Automatic Storage Management (ASM).
The Agent for Oracle in RMAN mode does not support backing up parameter files on raw devices.
While performing an RMAN backup job using the Agent for Oracle, if your agent machine is unable to resolve the backup server machine name (for instance, the Backup server is in a different domain using a separate DNS server), you can manually modify your mgmtsvc.conf and clishell.cfg files on both the Arcserve server machine and Arcserve Agent machine to ensure proper hostname resolution. For more information, see the Agent for Oracle guide.
Do not back up individual data files using RMAN.
