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 interactive 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.
