Example

This is an example on how to setup the configuration. You can tailor it to your specific needs:

$wgDataDumpDirectory = "<path>${wgDBname}/";

$wgDataDump = [
    'xml' => [
        'file_ending' => '.xml.gz',
        'generate' => [
            'type' => 'mwscript',
            'script' => "$IP/maintenance/dumpBackup.php",
            'options' => [
                '--full',
                '--output',
                "gzip:${wgDataDumpDirectory}" . '${filename}',
            ],
        ],
        'limit' => 1,
        'permissions' => [
            'view' => 'view-dump',
            'generate' => 'generate-dump',
            'delete' => 'delete-dump',
        ],
    ],
    'image' => [
        'file_ending' => '.zip',
        'generate' => [
            'type' => 'script',
            'script' => '/usr/bin/zip',
            'options' => [
                '-r',
                '<path>${filename}',
                "<path>${wgDBname}/"
            ],
        ],
        'limit' => 1,
        'permissions' => [
            'view' => 'view-dump',
            'generate' => 'view-image-dump',
            'delete' => 'delete-dump',
        ],
    ],
];

$wgAvailableRights[] = 'view-dump';
$wgAvailableRights[] = 'view-image-dump';
$wgAvailableRights[] = 'generate-dump';
$wgAvailableRights[] = 'delete-dump';

Note that ${filename} is replaced internally in the extension so make sure that it is always in a single string not in a double string.

The limit parameter specifies how many dumps can be generated for that wiki.
