because I still searching an alternative for my backup solution
In that case the only recommendation which i can give you is rsync,
because it is and it was my personal choice from the beginning and since late 2009.
https://rsync.samba.org/
It is also available as GUI-Application,
https://www.opbyte.it/grsync/
and here are some more interesting Links for you.

Back In Time could be another good choice and it is using
rsync and
cp as Backend.

Another one for you could be Timeshift.

It is available in Focal,
https://packages.ubuntu.com/focal/timeshift
and Jammy.
https://packages.ubuntu.com/jammy/timeshift
But that is everything what i can give you as recommendation and like i said
i never used anything else beside of rsync.
Even if you would use it on the Command Line only, the Syntax is not so complicated
like it looks in the beginning.
And once you got confirm with it, you can put all your Commands in a Textfile,
and save it as a Shell Script with a simple
#!/bin/bash
in the beginning, make it executable and you are good to go.
EDIT:
I was trying to find a simple and basic Tutorial about rsync, and i think i can't explain it
in a better way like this Guy.

And i have to agree with him about what he is saying on the end of the Video:
It is fast, efficient and useful.
