revert: small refactoring in the way backup value are handled
The current backup value may have two different values:
1. Do not try to do backup
2. Do backup if applicable
We are about to move to:
1. Do not try to do backup
2. Do backup if applicable
3. Do backup in all cases
So we change the current values to make room for the new one.
