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](https://askubuntu.com/questions/998082/is-it-necessary-to-keep-records-of-my-backups#comment1612949_998082) 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](https://askubuntu.com/revisions/68cedd77-27ad-49c8-8e1b-f4fda095117c/view-source) 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?`).
