One typically won’t get RAID in any fashion on a single bay NAS unit. At most one might get some sort of software RAID on other software based NAS programs. If one wants true RAID then they’ll need to buy a multi bay NAS box.
For the single bay My Cloud the best one can do is use the Safepoint / Backup feature to back up the My Cloud contents to another drive or location. Or one can use SSH to create a script (using Rsync or similar) to copy My Cloud files/content to another location. At least one can on OS3 firmware. Not sure if this is possible anymore on OS5 firmware.
