ELI5 - Process for backing up docker configs

Hello, I'm doing my darndest to learn docker but I'm a bit lost in the
sauce for understanding how to best structure the setup for backing up
and portability.

My current approach is that I keep my docker compose yaml file in git
(just using 1 for the time being) and all of my container configs live
in another directory outside of this git repo. I understand if I were
to move systems or my system were to fail, I'd need these docker
config folders to setup my containers on a new system.

As for backing the config folders up, I plan to relocate them to a
shared folder on my NAS. Is this the right way to do this or is there
a better way to approach this?

Hopefully the lingo is correct, still learning. Thanks a ton!

I keep my container data/volumes locally on the same host and every
hour I back this up using autorestic to a folder on my NAS. I like
this structure because the data is local to my host VM running on an
SSD and if my NAS disconnects or has an issue the containers stay
alive.
