Description:
Very efficient backup system based on the git packfile format,
providing fast incremental saves and global deduplication (among and
within files, including virtual machine images). Some of its features
are:

* It uses a rolling checksum algorithm and hence it can backup huge
  files incrementally.
* It uses packfile format from git, so one can access the stored data
  even if he doesn't like bup's user interface.
* It writes packfiles directly so it is fast even with huge amounts
  of data:
    it can track millions of files and keep track of hundreds or
    thousands of gigabytes of objects.
* Data is "automagically" shared between incremental backups without
  having to know which backup is based on which other one.
* One can make a backup directly to a remote bup server, without
  needing tons of temporary disk space on the computer being backed
  up. If the backup is interrupted halfway through, the next run will
  pick up where the previous backup left off.
* It can use "par2" redundancy to recover corrupted backups even if
  the disk has undetected bad sectors.
* Each incremental backup acts as if it's a full backup, it just
  takes less disk space.
* One can mount a bup repository as a FUSE filesystem and access the
  contents that way, or even export it over Samba.
