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 == |

9 |
|
| |
10 |
To 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 |
|
| |
19 |
The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. |
| |
20 |
|
| |
21 |
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. |

=== Restoring a Backup === |
| |
24 |
|
| |
25 |
Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database. |
| |
26 |
|
| |
27 |
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. |
| |
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.'' |
