A backup medium is assigned to each backup or restore action you perform. Backup media include files, tapes, autoloaders, and pipes.
You define separate backup media for each database instance. You can combine multiple backup media in a group of parallel backup media.
Note the following points:
· The recommended backup media for data backups are tape and autoloader. Data may also be backed up to pipes or files.
· Log backups are always made to files (version files).
· You should only use pipes if you are working with an external backup tool.
· Follow the naming conventions for backup media.
· For security reasons, archive your files or versions files.
In general, only archive files to a separate medium that can be stored in another location, where it is protected from fire and similar hazards.
You must follow the manufacturer's recommendations on how frequently backup media should be used.
