I want to do the following:
Exact mirror of C:\Users\Username
exclude C:\Users\Username\Appdata
include C:\Users\Username\Appdata\Mozilla (and some other dirs in Appdata)
My settings:
Left-Hand Side:
$USERPROFILE
Includion Masks:
(all)
\AppData\Roaming\Mozilla
Exclusion Masks:
\AppData
This works fine for the first backup.
Then it gives an error "Deletions are disabled because there were errors or discrepancies while scanning the folders"
How do I solve this?
