Hello grahamk,
This happend the last time after the upgrade as well, the config is not gone only not visible any more.
@dolbyman i did that, but again this is going to take a week or more like last time
So lost all my security cams (12 licenses) and ofcourse there is again no compasation in our costs.
Last time i had to spend over $100 as i had to backup my QNAP to get the base license back.
This is what they came back with :
Actually, QNAP NAS is a cloud storage not a backup system. We have provide multi RAID array let users can reduce data losing risky.
Therefor, we can not assume responsibility for your situation. Please understand, and sorry for any inconvenience caused.
So you buy a 900,00 euro QNAP device wich isn't an backup device .........
I do not understand why QNAP is releasing updates that haven't tested, this error should been seen !
