Backup files

I am running Metabase on lxc container:

I am connected to my database and have created some dashboard. But now I am worried that if something happens to my server I will lost all those dashboards
How can I create some backup for them? Are they store in some files? How I can access them?

Hi @Sieg
Post "Diagnostic Info" from Admin > Troubleshooting.
You would backup the Metabase application database, which stores all the information:

If I understand correctly all the info about users and dashboard are stored in the file `metabase.db.h2.db. I need to find it and copy it elsewhere.
But where is this file? I tried to look for it inside container, but I can not find it

@Sieg No, you're using Postgres for the application database ("application-database": "postgres",)
So you would backup the Postgres database. Search the internet for how to backup Postgres.
The latest release of Metabase is 0.40.2:
