Block-based backups

Block-based backups provide instant access to the backups. The block-based backups enable you to mount the backups by using the same file systems that you used to back up the data.

The File System agent's block-based backups support the following capabilities:

Mounting of a backup as a file system
Mounting of an incremental backup
Sparse backup support
Backups of operating system-deduplicated file systems as source volumes on Windows
Forever virtual full backups to DD
DD retention lock
Recoveries from DD

Block-based backups are useful for datasets that are under 10 TB with a single volume under 5 TB, and a daily change rate under 5%.
