Back up a datastore

Ferry makes no backup of a datastore. Write the data into a file yourself, on a schedule.

pg_dump writes the full database into one file

Ferry does not back up datastores

Make each backup yourself, on a schedule. When you delete a datastore, you lose its data.

Make a backup of Postgres

Terminal

docker exec ferry-ds-app-db pg_dump -U app_db app_db > app-db.sql

The command runs pg_dump in the container of the datastore app-db. app_db is the user and the database. The result is the file app-db.sql.

Production setup tells you what else to back up.

If a datastore stops

Ferry starts a stopped datastore again by itself. The volume keeps the data.

Delete a datastore

A delete removes the container and its volume. You lose the data, and there is no undo.
