Recently I moved my MyCloud to a different cabinet we purchased. Shortly thereafter, I was unable to access the unit. Therefore, I power cycled several times. And called WD Support. They say I have a faulty drive and I need to send it back to them or send it out for data recovery which starts at $700. Both options leave me devastated. I have my daughter’s photos and videos from birth on there. I read somewhere it is because of overheating- may have been caused by the new cabinet. Now I’m letting it cool off before I plug it back in and try.
A couple of other things to consider, as well. I would never put an enclosed drive inside a closed cabinet. I would also never lay the drive down on its side or lay anything on top of its vents, while its standing. That can lead to overheating as well.
If you only have the MyCloud as your working data store, and don’t have a copy somewhere else, then if the MyCloud fails (as ALL hard disks can), you have lost all your data.
If you have a backup copy somewhere, this failure will only be an inconvenience, rather than a devastating loss.
That’s what utilities like Safepoint are for; to support backups.
What cpt_paranoia is saying is critical for users to understand. If you have your data on your computer, and then put it on the My Cloud, then the My Cloud is a backup. However, once you move your data from your computer to the My Cloud, then the My Cloud is no longer a backup. It becomes the primary source that now needs to be backed up.
And as cpt says that’s what Safepoint is for - to backup the My Cloud. Just make sure that whatever drive you plug into the My Cloud, it’s at least the same size.
