Exporting a container creates an archive or image that can be sent to a different machine to be imported later. These exported archives can be used as container backups.

The export sub-command supports both UFS and ZFS storage. ZFS based containers will use ZFS snapshots. UFS based containers will use txz archives and they can be exported only when the jail is not running.
Usage: bastille export TARGET
