# Backing Up Aggregate¶

## Backup and restore forms and submissions with Briefcase¶

You can use ODK Briefcase to backup your forms and submissions by pulling them from Aggregate, and restore them by pushing them back to Aggregate.

Warning

Please, be aware that this procedure doesn't backup your server's configuration, users, exported forms, publisher configurations, and other important settings that you might still want to account for.

## PostgreSQL backup & restore¶

### Backup¶

1. Stop running Tomcat. This step, although optional, is recommended to produce full and coherent database dumps.
2. Produce a database backup file:

pg_dump [ dbname ] > [ backup destination ]

1. Start Tomcat if you stopped it on the first step.

You could get some errors depending on your particular PostgreSQL users and server configuration. Refer to the pg_dump documentation for more information on the options you can add to this command.

### Restore¶

1. Stop running Tomcat.
psql.exec -f [ backup file location ] [ dbname ]

psql -f [ backup file location ] [ dbname ]
