I use a TrueNAS server to backup my main server. Since this server is only used for backups there is no need to keep it running 24/7. To create backups now, I configured a cron job to 'wake on lan' my backup server, automatically have a snapshot taken and perform a replication on my main server 15 minuets later, and after four hours I have a cron job on my back server shut it down. Having an option on my main server to automatically shut down the remote backup server after replication completes would be very useful. This way I don't have to guess how long to keep the backup active for the replication to finish.
