    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`.
     5Trac backups are a copied snapshot of the entire [TracEnvironment project environment] directory, including the database. Backups can be created using the `hotcopy` command of [TracAdmin trac-admin].

    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.''

     12{{{#!sh

    15 [wiki:TracAdmin trac-admin] will lock the database while copying.''
     16The database will be locked while hotcopy is running.

    1718The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`.
    1819
    19 Please 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].

    23 Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database.
     24To restore an environment from a backup, stop the process running Trac, ie the web server or [TracStandalone tracd], restore the contents of your backup to your [TracEnvironment project environment] directory and restart the process.

    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.
     26If you are using a database other than SQLite, you'll need to restore the database from the dump file. The dump file is saved in the environment `db` directory.

     28To restore a PostgreSQL database backup, use the command:
     29{{{#!sh
     30$ psql -U <user> -d <database> -f /path/to/postgresql.dump
     31}}}
     32
     33The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the [TracIni#trac-database-option "[trac] database"] option of //trac.ini//.
     34
     35Similarly, for MySQL:
     36
     37{{{#!sh
     38$ mysql -u <user> -p <database> < /path/to/mysql.dump
     39}}}
