     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.''

     8== Creating a Backup ==
     9
     10To create a backup of a live TracEnvironment, simply run:
     11 {{{#!sh
     12$ trac-admin /path/to/projenv hotcopy /path/to/backupdir
     13}}}
     14
     15[wiki:TracAdmin trac-admin] will lock the database while copying.''
     16
     17The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`.
     18
     19Please note, the `hotcopy` command will not overwrite a target directory and when such exists the operation ends with error: `Command failed: [Errno 17] File exists:` This is discussed in [trac:ticket:3198 #3198].

     21=== Restoring a Backup ===
     22
     23Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database.
     24
     25To 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.
