You can set up raid1 on a single disk if the intent is to add another
disk later on. When you add the second (or third) disk run mdadm and
get the disk recognised in to the "array"
Else as other have suggested rsync in cron will do an easier job of
backing up on regular basis and will take less than a minute if run it
regularly, say half hour.
