     1= Trac Backup =
     2[[TracGuideToc]]
     3
     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`.
     5
     6  ''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.''
     7
     8== Creating a Backup ==
     9
     10To create a backup of a live TracEnvironment, simply run:
     11{{{
     12
     13  $ trac-admin /path/to/projenv hotcopy /path/to/backupdir
     14
     15}}}
     16
     17[wiki:TracAdmin trac-admin] will lock the database while copying.''
     18
     19The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`.
     20
     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 #3198].
     22
     23=== Restoring a Backup ===
     24
     25Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database.
     26
     27To restore an environment from a backup, stop the process running Trac (i.e. 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.
     28
     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.''
