You use tape backup and recovery to create tape archives and to retrieve data from tape archives.
You back up data from disk to tape for the following reasons:
- You can store the backup tapes at an off-site archive to protect the data against natural disasters.
- You can restore data from tape if an application or a user inadvertently corrupts or deletes files that cannot be recovered using the Snapshot copy feature.
- You can restore data from tape after you reinstall the file system on the storage system (for example, when migrating to larger disks or converting a single-volume storage system to a multivolume storage system).
