| 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`. |
| | 5 | Trac backups 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]. |

| | 24 | To 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. |
