I'd guess most don't use a scheduler, but rather do it as needed, on demand--whenever they feel the time is right. Not sure what advantage a regular automated schedule would have, particularly if you are going to be connecting the device and turning it on each and every time.
If you added or modified only a few files in the last few days, maybe you don't run a backup for a while. Conversely, you might have a burst of activity and want to backup several times a day. Even if you wanted to back up once a day only, I'm not sure using a scheduling application for a particular time of day would work out well.
