Block-level backup analyzes the source volume and backs up the extents (groups of contiguous blocks) for supported databases.
For more information on block-level backup and its benefits, see Block-Level Backups.
Notes
-
Block-level backups are supported only on Linux platforms. For more information, see the list of supported kernel versions below.
-
We do not support block-level backup if your data directory is present in the root volume.
-
Network File System (NFS) is not supported for PostgreSQL block-level backups.
-
Some agents and components require additional disk space, see Agents and Components Requiring Additional Disk Space.
