In this “simple” post I’ll show you how to configure btrbk to send to a remote Linux box your #subvolume, in order to #backup your data, also I’ll show you how to limit permissions to #btrbk using sudo and ssh_filter_btrbk.sh script file.

btrbk program uses the #btrfs #send / #receive feature, but it simplifies the management of subvolumes and the ability to send from your source box and receive in your target box the subvolumes over ssh.
