Linux Dump Command for Filesystem Backups

The dump command is used to backup filesystem data in a Linux system. It allows data from the filesystem to be backed up to tape or a file, so that data can be restored in case of system crashes or data loss. Typically, the dump command is used in conjunction with the restore command to recover backed-up data. With the dump command, one can perform full filesystem backups, incremental backups, or differential backups.
