+btrbk is a backup tool for btrfs subvolumes, taking advantage of btrfs specific capabilities
+to create atomic snapshots and transfer them incrementally to your backup locations.
+
+The source and target locations are specified in a config file, which allows to easily configure
+simple scenarios like "laptop with locally attached backup disks", as well as more complex ones,
+e.g. "server receiving backups from several hosts via ssh, with different retention policy".
+
+Key Features:
+
+*   Atomic snapshots
+*   Incremental backups
+*   Configurable retention policy
+*   Backups to multiple destinations
+*   Transfer via ssh
+*   Resume of backups (if backup target was not reachable for a while)
+*   Encrypted backups to non-btrfs destinations
+*   Wildcard subvolumes (useful for docker and lxc containers)
+*   Transaction log
+*   Comprehensive list and statistics output
+*   Resolve and trace btrfs parent-child and received-from relationships
+*   Display file changes between two backups
+
+btrbk is designed to run as a cron job for triggering periodic snapshots and backups, as well
+as from the command line (e.g. for instantly creating additional snapshots).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
