The only way to really keep your data safe is to back it up to a different device - ideally more than one. USB drives are a cost effective way; though I prefer the convenience of NAS->NAS backups.
Depending on data recovery is extremely risky, and there lots of people here who have discovered that the hard way. Disks can and do fail in rapid succession, and there are cases where power surges damage all the disks and the chassis. Unexpected shutdown (power loss, hardware failure, or software crashing) can give you an out of sync array. Plus there's theft, fire, water damage, etc... and the possibility of human error.
However, if data recovery were needed for some reason, there are some options. Netgear offers a service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service and there are some other ones out there. You can also use RAID recovery software - for instance R-Studio ( https://www.r-studio.com/ ). It is generally advisable to clone the disks (doing sector by sector copies to known good ones) and then attempt recovery with the clones. One reason is that you don't want the disks to fail completely during recovery. Another is that you don't want to accidentally do more damage in your recovery attempts.
I haven't seen a step-by-step guide - and since there are a lot of scenarios here, I don't think it'd be easy to create a comprehensive one.
Thanks for the quick response!
I agree backup if best. The problem is size. I have not the finances to get an additional backup system in place with 16TB of disks. My interest is in failure of the Readynas itself. Disks failures have happend a few times so far, but easily fixed by replacing the faulty disk. In case of just preparing for a readynas failure, would you be able to go into some more details on the best solution?
What software and hardware (cables/system) do I need to have ready?
And does readynas not have a 4-bay readynas that is still for sale that can be used to swap the disks into and use this device instead?
I am handy enough with computers, however need to be sure that I use a succefull tested approach. :-)
Thanks again!!
