Dump/restore
Dump examines files in a filesystem, determines which ones
need to be backed up, and copies those files to a specified disk, tape
or other storage medium. Subsequent incremental backups can then be
layered on top of the full backup.
The restore command performs the inverse function of dump; it
can
restore a full backup of a filesystem. Single files and directory
subtrees may also be restored from full or partial backups in
interractive mode.
Features include:
- Backup ext2/ext3 filesystems to tape or another disk
- Use dump on unmounted and
read-only filesystems
- Use dump on idle
filesystems if you sync before dumping
- Never changes the filesystem while dumping it
- Used across a network by piping its output through bzip2
then ssh
- Dump levels, offering a full dump or incremental backups
- Transparently write archives which span more than one tape
- Handles all kinds of strange things, such as files with
holes, files with unbelievably long filenames, files with strange
symbols in the filenames
- Non-interactive and interactive restores
- Bypasses the kernel's filesystem interface
