Versioning: keep only X days

[markusoft]

I have a folder pair that sync's - everything works great
my next pair I would like to SKIP 5 days (Keep 5 days) or (Ignore Last X)
left side (dummy) - an empty directory right side (backup) - Mirror
filter is *.pst
therefore it would DELETE all but the last 5 PST backups

I would like Skip X days or ability to put -5 in Last X days
This way I do not have to delete manually my backups for space, can let it roll..
(in my delete file versioning)

Put in a SCHEDULER Please...
Run Prior / Close Prior

This fits in the discussions on more refined Version control.
See e.g. here.
