Backups can be created using the `hotcopy` command in [wiki:TracAdmin trac-admin]. + +**Note**: Trac uses the `hotcopy` nomenclature to match that of [Subversion](http://subversion.tigris.org/), 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: +```#!sh +$ 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`. + +Please note, the `hotcopy` command will not overwrite a target directory and when such exists, the operation ends with an error: `Command failed: [Errno 17] File exists:` This is discussed in [trac:ticket:3198 #3198]. + +## Restoring a Backup + +To restore an environment from a backup, stop the process running Trac, ie the Web server or [wiki:TracStandalone tracd], restore the contents of your backup (path/to/backupdir) to your [wiki:TracEnvironment project environment] directory and restart the service. + +To restore a PostgreSQL database backup, use the command: +```#!sh +psql -U <user> -d <database> -f postgresql.dump +``` + +The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the `[trac]` `database` option of //trac.ini//. + +---- +See also: TracAdmin, TracEnvironment, TracGuide, [trac:TracMigrate TracMigrate] |
