Introduction to data backup to tape

About data backup  

Although data backup can also mean copying data to standard output, for this chapter, data backup means copying data from disk to tape.

Reasons to back up data from disk to tape  

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 from snapshots.
• You can restore data from tape after you reinstall the file system on the filer (for example, when migrating to larger disks or converting a single-volume filer to a multivolume filer).
