    1 = Trac Backup
    2 
    3 [[TracGuideToc]]
    4 
    5 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].
    6 
    7 '''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 == Creating a Backup
    10 
    11 To create a backup of a live TracEnvironment simply run:
    12 {{{#!sh
    13 $ trac-admin /path/to/projenv hotcopy /path/to/backupdir
    14 }}}
    15 
    16 [wiki:TracAdmin trac-admin] will lock the database while copying.
    17 
    18 The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`.
    19 
    20 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].
    21 
    22 === Restoring a Backup
    23 
    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.
    25 
    26 To restore a PostgreSQL database backup, use the command:
    27 {{{#!sh
    28 psql -U <user> -d <database> -f postgresql.dump
    29 }}}
    30 The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the `[trac]` `database` option of //trac.ini//.
