What My Cloud firmware are you running? The older first generation v4.x or the newer v2.x used on second gen My Cloud’s? If you are using the v4.x firmware you can schedule Safepoints to run at set times. If you have the second gen v2.x firmware My Cloud there is no schedule option build into the Backup feature. Stupid but that’s the deal. Feel free to voice your opinion as others have done in the following Cloud Ideas discussion.

Unofficially one workaround to this lack of a scheduler in the Backup feature is to use Rsync. Use the forum search, magnifying glass icon upper right, and search for Rsync to find several past discussions on how to use Rsync to automate backing up a My Cloud.
Edit to add: And no, you cannot downgrade a second generation v2.x firmware My Cloud to run the older first gen v4.x firmware.
