Configuration backup?

Hi, I am new to Homarr. I had mounted Homarr on a Proxmox Container, and had backups of the entire container. I switched Proxmox Node, but the backups got corrupted and I could not recover them. I had to start from scratch to configure again all the access and preferences.
Is there any way to make a Backup of only the Preferences and Configuration, so I can recover it after some disaster?
Thanks!
