= Trac Backup = [[TracGuideToc]] Since Trac uses a database backend, some extra care is required to safely create a backup of a [wiki:TracEnvironment project environment]. Luckily, [wiki:TracAdmin trac-admin] has a command to make backups easier: `hotcopy`. ''Note: Trac uses the `hotcopy` nomenclature to match that of [http://subversion.tigris.org/ Subversion], to make it easier to remember when managing both Trac and Subversion servers.'' == Creating a Backup == To create a backup of a live TracEnvironment, simply run: {{{ $ trac-admin /path/to/projenv hotcopy /path/to/backupdir }}} [wiki:TracAdmin trac-admin] will lock the database while copying.'' The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. === Restoring a Backup === Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database. To restore an environment from a backup, simply stop the process running Trac (i.e. the Web server or [wiki:TracStandalone tracd]), restore the directory structure from the backup and restart the service. ''Note: Automatic backup of environments that don't use SQLite as database backend is not supported at this time. As a workaround, we recommend that you stop the server, copy the environment directory, and make a backup of the database using whatever mechanism is provided by the database system.'' ---- See also: TracAdmin, TracEnvironment, TracGuide {{{ #!html
