Can this be used as a backup and restore tool?

[Nostradamus1973]

Good evening,

I've been using Jellyfin for a few years and recently lost everything because I tried backing up the /etc/jellyfin and the /var/lib/jellyfin/data folder as suggested by a few forums and wrecked everything several times. I'm really hoping your script is the sort of thing I've been seeking out for quite some time now.

So, I wanted to know if I fill out the variables in your script, will I be able to use it as a backup and restore? Or, can it onlly migrate?

Thank you
