If you have a My Cloud, NOT a My Cloud Home you can use the backup feature included in the My Cloud Dashboard (either Safepoint or Backup) to backup the contents of the My Cloud to a USB hard drive attached to the My Cloud… While the initial backup will take a very long time if one has a lot of data on the My Cloud, subsequent backups only backup new/changed files on the My Cloud. See the User Manual for the My Cloud for more information on how to backup the My Cloud to a USB hard drive attached to the My Cloud USB port.
There are other options using SSH to setup a backup process to another location but its more complicated to setup. Here is one such past discussion on alternatives to the My Cloud Dashboard Safepoint.
