Problem recovering from backup

[killdozer (Brutalise me with music)]

Hi @Jens_Lagerqvist, I’m not support but while you’re waiting I’ll offer some second rate help

I don’t want to alarm you but the first screenshot (top left) has a file called README_FOR_DECRYPT.txtt. At first I wondered if you had encryption turned on but a quick Google suggests that you might be suffering a ransomware attack:

This would mean that all of the backup files are encrypted and are therefore unreadable by Roon, which fits the behaviour you’re seeing. There are a few (lot?) of cases of this across NAS devices. This is covered in another forum thread here:

Massive malware attack on QNAP

Except me and 28 others, so far. You can see where the link goes (bleeping computer) by hovering on the link. I noticed that my QNAP installed or updated and ran a malware remover this morning. It didn’t find anything and my files are intact. From the discussion at bleeping computer, it looks like many machines have been affected world wide. I’m now headed to QNAP to see if there is more preventive action we should take. Thank you dpstjp for the heads up.

This thread holds a discussion for affected users and you might get some joy there:

DON’T jump to the conclusion that this is the case but you’re certainly showing the symptoms and it’s worth investigating. Sorry for breaking what might be bad news.
