Manual:DumpBackup.php

dumpBackup.php dumps the wiki page database into an XML interchange wrapper format for export or backup.

The XML output is sent to standard output (stdout); progress reports are sent to standard error (stderr).

This is not a full backup of the wiki database, as it does not include users, passwords, etc.

Options
From MediaWiki : This script dumps the wiki page or logging database into an XML interchange wrapper format for export or backup.

This script connects to the database using the username and password defined by $wgDBadminuser and $wgDBadminpassword, which are normally set in AdminSettings.php. The file AdminSettings.php can be created manually from AdminSettings.sample, and is not installed by default. Usually $wgDBadminuser is a user with more privileges than the one in $wgDBuser (set in LocalSettings.php), but for running dumpBackup.php no extra privileges are required, so the usernames and passwords may be the same. If the variables are not set, dumpBackup.php will fail when trying to connect to the database: $ php dumpBackup.php --full DB connection error: Unknown error

Examples
To get the output of the script in to a file, it's required to forward the output into a file. For example, to save the output into a file named dump.xml, use: php dumpBackup.php --full > dump.xml

To restrict output by namespace, try: php dumpBackup.php --current --filter=namespace:10 > templates.xml

If you want to include multiple namespaces, try: php dumpBackup.php --current --filter=namespace:10,11 > templates_plus_template_talk.xml

Example usage of a plugin: php dumpBackup.php \ --plugin=AbstractFilter:extensions/ActiveAbstract/AbstractFilter.php \ --current \ --output=gzip:/dumps/abstract.xml.gz \ --filter=namespace:NS_MAIN \ --filter=noredirect \ --filter=abstract or php dumpBackup.php \ --plugin=MathMLFilter:../extensions/MathSearch/maintenance/MathDump.php \ --current \ --filter=namespace:NS_MAIN \ --filter=mathml When using the --stub option, the output can be further processed with dumpTextPass.php.
