How to spread backups out?

[hellomotow]

Right now I have set it to do backups every 2 days. The current backups would look like this

13/11
11/11
09/11
07/11

How can I spread them about a bit? I would like to keep one backup from 1+ month ago, one from a week ago, one from two days ago and one from today.

Anyone? One of my nodes did this in the past automatically

There is no automatic way to do this, you have to do it manually.
