While backing up my drives, the TNAS crashed several times as it has been doing since the last update and now the TNAS wants to go through initilization again. I can not login via TNAS anymore!!

How can I access my files to try and back up more stuff, so I can finally get this damned thing formatted to EXT4 ?

Device is F4-210
