gibak is a backup tool based on git. Since gibak builds upon the infrastructure offered by Git, it shares its main strengths:

• speed: recovering your data is faster that cp -a...
• full revision history
• space-efficient data store, with file compression and textual/binary deltas
• efficient transport protocol to replicate the backup (faster than rsync)

gibak uses Git's hook system to save and restore the information Git doesn't track itself such as permissions, empty directories and optionally extended attributes and mtime fields.

You can read more about gibak here.

What's new in 0.3.0

• OSX support
• support for extended attributes both on Linux and OSX (it might work on other systems if their getxattr(2) interface matches Linux or OSX's).
• a few bugfixes

Read README.upgrade if you used earlier versions of gibak and want to use extended attributes.

Some FAQs

(This will eventually be moved to a new node.)

Will the repository grow monotonically? Can I delete older history? What about large files?
