Welcome to the Community!

Sorry to hear on what happened Smiley Sad Glad to hear as well that you have backup of your data elsewhere aside from the NAS which is the best.

It seems that your disks were having the same fate, it's just that they failed all at the same time which is very unfortunate, Were you able to download the logs from your NAS? Multiple drive failure may require Data Recovery services if you contact Support for assistance but there is also a chance that there was only few bumps that the array went out of sync so chances of remounting or rebuilding it is there provided that disks are still healthy.

If you want to DIY, since you have completed re-sync of Disk 3, Disk 2 or Disk 1 might need to be cloned to get back to degraded mode then add a new drive to re-sync and get back to normal RAID 5 protected. Alternatively, the easiest method would be to replace the failed drives and do a Factory reset then send the backup data back to the NAS.

Cloning can be done thru SSH or using apps recommended by the Community.
