i find that behaviour inconsistent:
if the maxfiles is invalid and we deselect backups, the maxfiles field 
is still enabled, event tough it has no meaning in this configuration, 
since we are unable to make backups on this storage now

something like this would be better imho:

when the maxfiles field gets disabled, reset it to the value it had, to 
reflect that we do not change the backend value
