     5Backups 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
     11To 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
     18The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`.
     19
     20Please 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
     24To 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
     26To restore a PostgreSQL database backup, use the command:
     27{{{#!sh
     28psql -U <user> -d <database> -f postgresql.dump
     29}}}
     30The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the `[trac]` `database` option of //trac.ini//.
