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.
-`custom/` - All config or customization files in `custom/`.
-`data/` - Data directory (APP_DATA_PATH), except sessions if you are using file session. This directory includes `attachments`, `avatars`, `lfs`, `indexers`, SQLite file if you are using SQLite.
-`repos/` - Complete copy of the repository directory.
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.
There are a few caveats for using the `dump` command with Docker.
The command has to be executed with the `RUN_USER = <OS_USERNAME>` specified in `gitea/conf/app.ini`; and, for the zipping of the backup folder to occur without permission error the command `docker exec` must be executed inside of the `--tempdir`.
\*Note: `--tempdir` refers to the temporary directory of the docker environment used by Gitea; if you have not specified a custom `--tempdir`, then Gitea uses `/tmp` or the `TMPDIR` environment variable of the docker container. For `--tempdir` adjust your `docker exec` command options accordingly.
Repository Git Hooks should be regenerated if installation method is changed (eg. binary -> Docker), or if Gitea is installed to a different directory than the previous installation.
This ensures that application and configuration file paths in repository Git Hooks are consistent and applicable to the current installation. If these paths are not updated, repository `push` actions will fail.
There is also no support for a recovery command in a Docker-based gitea instance. The restore process contains the same steps as described in the previous section but with different paths.
