Luckily, [wiki:TracAdmin trac-admin] has a command to make backups easier: `hotcopy`.5 Trac 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 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.'' 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. 7 8 8 == Creating a Backup ==9 == Creating a Backup 9 10 10 To create a backup of a live TracEnvironment ,simply run:11 11 To create a backup of a live TracEnvironment simply run: 12 {{{#!sh 12 13 $ trac-admin /path/to/projenv hotcopy /path/to/backupdir 13 14 }}} 14 15 15 [wiki:TracAdmin trac-admin] will lock the database while copying.
