ZFS Snapshot Daemon is written in python, and it can remotely manage ZFS snapshotting and backup from a central back up server. This is the security plugin command for sshd that implements ForceCommand functionality, or the command functionality in the .ssh/authorized_keys file (See the sshd_config(8) and sshd(8) man pages respectively).

It executes commands from the SSH_ORIGINAL_COMMAND variable after checking them against a list of configured regular expressions.
