Backup

warning

For better protection, the created backup should be transferred off the host to an independent storage location, ensuring it cannot be overwritten or lost in the event of a host failure.

note

If you are using docker-compose, you are using Docker Compose v1, which has been deprecated. Docker Compose commands refer to Docker Compose v2. Consider upgrading your docker setup, see Migrate to Compose V2

Backup​

Create backup file teslamate.bck:

docker compose exec -T database pg_dump -U teslamate teslamate > ./teslamate.bck
note

-T is important if you add this line a crontab or the backup will not work because docker will generate this error the input device is not a TTY

note

Be absolutely certain to move the teslamate.bck file to another safe location, as you may lose that backup file if you use a docker-compose GUI to upgrade your teslamate configuration. Some GUIs delete the folder that holds the docker-compose.yml when updating.

note

If you get the error No such service: database, update your docker-compose.yml or use db instead of database in the above command.

note

If you changed TM_DB_USER in the .env file from one of the advanced guides, make sure to replace the first instance of teslamate to the value of TM_DB_USER in the above command.
