Re: power and disk lights blinking but "Device Is Offline"
Thankfully I can access the volumes using AFP. What do you think about removing one of the drives before either - backing up the data over the network from the nas - performing the copy using a HDD enclosure and avoiding the ReadyNas until I can do a factory reset
Re: power and disk lights blinking but "Device Is Offline"
Your PC will not recognize the format of the NAS drive, so putting one in a USB enclosure or dock is not an option. Since you can't get into the GUI to set up a backup to an attached USB drive, the fastest method is to copy over the LAN to a drive attached to a PC. You could attach the USB drive to the NAS, but then the data would be going over the LAN twice -- from NAS to PC and then PC to NAS.
Your symptoms are similar to what I've seen with missing or corrupt configuration files. if that is not due to an over-full OS (aka root) partition, then an OS re-install will normally fix it -- you won't need a full Factory Default. But even though that should not harm your data, it is best to make the backup while you still have SMB access. And if that fails, you are already prepared for a Factory Default.

Thankfully I have "extFS for Mac" from paragon software so i will be able to access the "raw" disks from the Duo.
I powered it off last night, removed both drives, reinstalled the first drive and powered it back up. It appears to be "stable" so I will try to use the backup jobs to back up the disks.
I was also able to ssh into the Duo. System disk is not full. Whew.
