+
+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`.
+
+Please, 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].
+
+=== 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, 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.
