Opalsync is an open source framework for making backup of local or remote computers. It is designed for backup to disk using rsync as backend, but can be extended with other ways.

It generally store backup data as one full copy of the latest, and then only store the differences from the previous backup syncronizations. This make it easy to restore recently lost data and saves a lot of disk-space.

Features

• Extendable with new ways of making the backup
• Tree structure of backup objects, with possibility for inheritance
• Open source
• Replaced files put in a separate directory
• Reduction rules by merge or removal (introduced in version 1.3)
