     1= Trac Backup = 
     4Since 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`. 
     6  ''Note: Trac uses the `hotcopy` nomenclature to match that of [ Subversion], to make it easier to remember when managing both Trac and Subversion servers.'' 
     8== Creating a Backup == 
     10To create a backup of a live TracEnvironment, simply run: 
     13  $ trac-admin /path/to/projenv hotcopy /path/to/backupdir 
     17[wiki:TracAdmin trac-admin] will lock the database while copying.'' 
     19The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. 
     21Please, note, that hotcopy command does not overwrite target directory and when such exists, hotcopy ends with error: `Command failed: [Errno 17] File exists:` This is discussed in trac:ticket:3198. 
     23=== Restoring a Backup === 
     25Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database.  
     27To 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. 
     29  ''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.''
