## Backup Consistency
To ensure the consistency of the Gitea instance, it must be shutdown during backup.
Gitea consists of a database, files and git repositories, all of which change when it is used. For instance, when a migration is in progress, a transaction is created in the database while the git repository is being copied over. If the backup happens in the middle of the migration, the git repository may be incomplete although the database claims otherwise because it was dumped afterwards. The only way to avoid such race conditions is by stopping the Gitea instance during the backups.
## Backup Command (`dump`)
Switch to the user running Gitea: `su git`. Run `./gitea dump -c /path/to/app.ini` in the Gitea installation

Intermediate backup files are created in a temporary directory specified either with the
`--tempdir` command-line parameter or the `TMPDIR` environment variable.
## Backup the database
The SQL dump created by `gitea dump` uses XORM and Gitea admins may prefer to use the native the MySQL and PostgreSQL dump tools instead. There are still open issues when using XORM for dumping the database that may cause problems when attempting to restore it.
```sh
# mysql
mysqldump -u$USER -p$PASS --database $DATABASE > gitea-db.sql
# postgres
pgdump -U $USER $DATABASE > gitea-db.sql
```
### Using Docker (`dump`)
There are a few caveats for using the `dump` command with Docker.
