TracBackup
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.'' … … 9 9 10 10 To create a backup of a live TracEnvironment, simply run: 11 {{{ 12 13 $ trac-admin /path/to/projenv hotcopy /path/to/backupdir 14 11 {{{#!sh 12 $ trac-admin /path/to/projenv hotcopy /path/to/backupdir 15 13 }}} 16 14 … … 19 17 The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. 20 18 21 Please , note, that hotcopy command does not overwrite target directory and when such exists, hotcopy 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]. 22 20 23 21 === Restoring a Backup === 24 22 25 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. 26 24 27 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. 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.'' 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//. 30 30 31 31 ----
