Data Manager performs a file system level full and incremental backup using block-based backup (BBB) technology. During the backup, the application agent scans a volume or a disk in a file system and backs up all the blocks that are in use in the file system. Unlike the traditional file system backup, BBB supports high-performance backups with a predictable backup window.
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 backup the data.
The File System Agent's block-based backups support the following capabilities:
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%.
