Example

This is an example of how to set up the configuration. You can tailor it to your specific needs:

$wgDataDumpDirectory = "/var/backups/${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',
                "${wgDataDumpDirectory}" . '${filename}',
                "$IP/images/"
            ],
        ],
        'limit' => 1,
        'permissions' => [
            'view' => 'view-dump',
            'generate' => 'generate-dump',
            'delete' => '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.

Troubleshooting

If you're experiencing issues with failed data dumps, you can look at your Job Queue 's log file. You can search for DataDumpGenerateJob to find an area where the Job Queue is running your dump.

PHP binary location

If your log file contains something similar: [exec] Possibly missing executable file: '/usr/bin/php', then you might need to set $wgPhpCli to a correct value for your environment. You can use whereis php to double check.

Zip Tooling

If your log file contains something similar to: [exec] Possibly missing executable file: '/usr/bin/zip' then you need to ensure the appropriate zip tooling for your job is installed on your Host machine.
