Doubts on incremental backup and command repetition

This doesn't quite make sense.  Your target and compare-dest dirs are
the same dir (the compare-dest is relative to the target so ../dest is
the same thing).  Also, --backup only matters when rsync is deleting
or overwriting something which it isn't doing.

I would suggest using --link-dest instead of --compare-dest or --backup
