 == Creating a Backup ==
+
 To create a backup of a live TracEnvironment, simply run:
 {{{
-  $ trac-admin /some/where/mytracenv hotcopy /my/vault/mytracenv-backup
+
+  $ trac-admin /path/to/projenv hotcopy /path/to/backupdir
+
 }}}
 
-'''Note:''' TracAdmin will lock the database while copying.
+[wiki:TracAdmin trac-admin] will lock the database while copying.''
 
-The resulting backup copy is safe to handle using standard file-based backup tools like tar or dump/restore.
+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 TracEnvironment directory structure, including the SQLite database. 
 
-To restore an environment from a backup, simply shut down your Trac service (Web server or tracd), restore the directory structure from backup and restart the service.
+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.
+
+  ''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.''
