How to backup photo's in Netbox docker container

[alittle3]

I'm running Netbox version v4.0.9 as a docker container. I'm setting up a replacement server and want to copy the information to the new server. I can run the following commands and back up everything except pictures.

Only start the DB

docker compose up -d postgres

Take a DB backup

docker compose exec -T postgres sh -c 'pg_dump -cU $POSTGRES_USER $POSTGRES_DB' | gzip > db_dump.sql.gz

Stop the database

docker compose down

Restore the database

docker compose up -d postgres
gunzip -c db_dump.sql.gz | docker compose exec -T postgres sh -c 'psql -U $POSTGRES_USER $POSTGRES_DB'

How do you back up any pictures that you have put into Netbox?

Thank you!
