Yes, it works just as great with command line access only. Here's an example:
sudo timeshift --create --comments "A new backup" --tags D
Comment can be anything, it's your display name. Tags can be D, W, M or O which is daily, weekly, monthly or on demand backup. To restore a snapshot later you simply type:
sudo timeshift --restore
And a menu will show from where you can see available snapshots and choose which one to restore.
