Types of tape backup supported by Data ONTAP

Data ONTAP supports two types of tape backup: the dump backup and the SMTape backup.

Tape backup using dump

Dump is a Snapshot copy-based backup to tape, in which your file system data is backed up to tape. The Data ONTAP dump engine backs up files, directories, and the applicable ACL information to tape. Dump supports level-0, differential, and incremental backups.

Tape backup using SMTape

SMTape is a Snapshot copy-based high performance disaster recovery solution that backs up blocks of data to tape. You can use SMTape to perform volume backups to tapes. However, you cannot perform a backup at the qtree or subtree level. SMTape supports level-0, differential, and incremental backups.
