Backup isnt working - whats wrong?

[czdavid]

Hello,

I dont understand why isnt backup on my server with Promox working.
I set for backup "local" storage.

I tried it twice with same error. How can I fix it?
Thank you for your help...

There is backup log:

you cannot dump into the snapshot.

use another backup dir. search the forum, this issue is discussed several times already.
