Database backup not created on some scenarios

[DahmaniAdame]

Describe the bug

Changing DB inclusion pairing with a change of frequency seems to result into backups no longer including DB even if it's enabled.

A clear and concise description of what the bug is.

On extreme caches, the backup list will be erased and/or show an empty page.

To Reproduce
Steps to reproduce the behavior:

1- delete all backups
2- make sure that only files backup on
3- backup now
4- enable DB and change it’s frequency
5- backup now ⇒ DB backup is not there

or

1- create 1st backup while DB off
2- enable DB and change frequency to be different than files
3- backup now

Expected behavior

The DB backup should be generated after enabling it in the backup settings.
The backup history should persist and be visible after a page refresh.
Modifying the backup settings (e.g., enabling DB and changing frequency) should not cause backup history to be erased.
