Creating a Backup
To create a backup of a live TracEnvironment, simply run:
$ trac-admin /path/to/projenv hotcopy /path/to/backupdir
trac-admin will lock the database while copying.
The resulting backup directory is safe to handle using standard file-based backup tools like
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 #3198.
Restoring a Backup
To restore an environment from a backup, stop the process running Trac, ie the Web server or tracd, restore the contents of your backup (path/to/backupdir) to your project environment directory and restart the service.
To restore a PostgreSQL database backup, use the command:
psql -U <user> -d <database> -f postgresql.dump
<database> option is the same as the database connection string in the
database option of trac.ini.
