Trac Backup
v3 v4 2 2 [[TracGuideToc]] 3 3 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`.4 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]. 5 5 6 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.'' … … 17 17 The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. 18 18 19 Please note, the `hotcopy` command will not overwrite a target directory and when such exists the operation ends witherror: `Command failed: [Errno 17] File exists:` This is discussed in [trac:ticket:3198 #3198].19 Please note, the `hotcopy` command will not overwrite a target directory and when such exists, the operation ends with an error: `Command failed: [Errno 17] File exists:` This is discussed in [trac:ticket:3198 #3198]. 20 20 21 21 === Restoring a Backup === 22 22 23 Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database. 23 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. 24 24 25 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. 25 To restore a PostgreSQL database backup, use the command: 26 {{{#!sh 27 psql -U <user> -d <database> -f postgresql.dump 28 }}} 29 The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the `[trac]` `database` option of //trac.ini//. 26 30 27 31 ----
