User’s guide
abgleich is a simple ZFS sync tool. It displays source and target ZFS zpool, dataset and snapshot trees. It creates meaningful snapshots only if datasets have actually been changed. It compares a source zpool tree to a target, backup zpool tree. It pushes backups from a source to a target. It cleanes up older snapshots on the source side if they are present on the target side. It runs on a command line and produces nice, user-friendly, human-readable, colorized output. It also includes a GUI.
Warning
This manual describes what makes abgleich special and how it runs on top of ZFS. It does NOT substitute the OpenZFS documentation. Please read the latter first if you have never used ZFS before. Besides the official documentation, an excellent yet dated basic introduction into ZFS is provided in a series of blog posts by Aaron Toponce.
