Yet Another Rsync Rotator is a simple, rsync-based online backup tool, doing away with some of the existing tools' limitations that bug me most. It is usable but not feature-complete.
- Takes snapshots of filesystem trees using rsync, saving lots of space hardlinking identical files
- Supports backing up to a remote host (push) as well as backing up remote hosts (pull)
- Properly maintains daily, weekly, ... backups even when run irregularily (e.g. on a laptop)
