Add possibility to ignore deleted files in certain locations

[Wastus]

I'd love to see a feature where I can specify files / folders (or a regular expression) which should not count to the deleted file count. But are still synced (so I can't use the SnapRAID exclude feature).

I know that this also means, that the script will have to parse the output of the diff instead of just reading the summary.

Why would I need something like this?

I have a rolling backup running onto my SnapRAID, certain parts will get deleted after a day or two and new things will pop up. This is a mess with counting the deleted files, you never know how much it'll be and honestly I don't really care. Of course someone could just delete my whole backup and the sync would just continue when the backup is excluded from counting, but that is a risk I'll take over just setting the delete count to 1000 and miss that I deleted the wrong folder in some after work delirium.
