    4 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`.
     5Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the database. Backups can be created using the `hotcopy` command in [wiki:TracAdmin trac-admin].

    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.''

    1718The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`.

    19 === Restoring a Backup ===
     20Please 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].

    21 Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database.
     22=== Restoring a Backup
    2223
    23 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.
     24To 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.
    2425
    25   ''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.''
     26To restore a PostgreSQL database backup, use the command:
     27{{{#!sh
     28psql -U <user> -d <database> -f postgresql.dump
     29}}}
     30The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the `[trac]` `database` option of //trac.ini//.
