    Does xfsdump support incremental backups?
    In addition, xfsdump supports incremental backups, and can exclude files from a backup using size, subtree, or inode flags to filter them. In order to support incremental backups, xfsdump uses dump levels to determine a base dump to which a specific dump is relative. The -l option specifies a dump level (0-9).

  6. People also ask
    How does xfsdump work?
    The xfsdump utility uses dump levels to determine a base backup to which other backups are relative. Numbers from 0 to 9 refer to increasing dump levels. An incremental backup only backs up files that have changed since the last dump of a lower level: To perform a full backup, perform a level 0 dump on the file system.

    Can xfsdump clone a file system?
    You can also restore individual files and directory hierarchies from backups. Unlike an LVM snapshot, which immediately creates a sparse clone of a volume, xfsdump takes time to make a copy of the file system data.

    What are xfs dump levels?
    With dump levels, you can implement sophisticated rotational backup schedules. For example, a weekly full level 0 dump, daily level 1 incrementals, and hourly level 2 increments. XFS dumps at all levels remain fully valid, restoring to the exact filesystem state from that point in time.

    Does xfsdump overwrite existing backups?
    By default, xfsdump never overwrites existing backups. Create incremental backups. The xfsdump utility uses dump levels to determine a base backup to which other backups are relative. Numbers from 0 to 9 refer to increasing dump levels.

    Does xfsdump dump unmounted filesystems?
    xfsdump does not dump unmounted filesystems. The dump frequency field of /etc/fstab is not supported. xfsdump uses the alert program only when a media change is required. xfsdump requires root privilege (except for inventory display). xfsdump can only dump XFS filesystems.
