DAR
Disk ARchive (DAR) is a full featured archiver with support
for differential backups, slices, compression, ATTR/ACL support. DAR
also supports pipes for remote operations, including with ssh. It can
remove files during restoration.
This application can store a backup in several files (called
"slices" in the following) of a given size, eventually pausing or
running a user command/script before starting the next slice. There are
graphical user interfaces available for DAR
including KDar and DarGUI.
Features include:
- Directory tree snapshot recording the inode status
of files
- Compression including:
- Per-file compression with gzip
or bzip2 (as opposed to compressing the whole archive)
- Fast extraction of files
- Fast listing of archive files
- Strong Blowfish encryption
- Flat restoration
- Filters
- Support slices, archives split over multiple files of a
particular size
- Direct Access - Dar first reads the catalogue
(i.e. the contents of the
backup), then it goes directly to the location of the saved file(s) you
want to restore and proceed to restoration
- Full or differential backup
- Hard links
- Extended attributes
- Archive testing - detect data corruption in the archive
- Remote operations
- Isolation - the catalogue (i.e. the contents of
an archive) can be extracted (this operation is called isolation) to a
small file, that can in turn be used as reference for differential
archive
- Re-shape slices of an existing archive
- Scrambling - the archive can be scrambled by
using a pass phrase
- Data protection
- Archive merging - merge two existing archives into one
archive
- Archive subsetting - define a
subset of files from an archive and put them into a new archive without
having to really extract these files to disk
