Yes, the question can be flagged for moderator assistance, but that's inappropriate with this question. You should ask a new question since the edit changed the nature of the question. I added the following comment to that question to explain:
It's not really allowed to change a question so that good answers are no longer good answers. Since this is now Déjà Dup-specific and invalidates the accepted answer, you should ask a new question instead of editing this question. I've reverted your edit, and you can click here to see the newer version of your question so that you can re-ask it (the newer question title is
Backup with Deja-dup: keep records to keep history vs keep lastest backup to save memory?).
This question on Meta Stack Exchange goes a bit into the changing the nature of questions.
