[PVE-User] disk parameter "backup=no" is now "backup=0"?

[Nicola Ferrari (#554252)]

Hi everybody.
I upgraded my cluster to pve4 some weeks ago.

I noticed that if I select the "no backup" option on a disk, the string 
added to the config is now "backup=0".
In the past (and also now on my previously configured disks), that 
option is "backup=no"

are they compatible?
should I make any modification to my old configs?

Thanks!
Nick
