Backup MediaWiki MediaFiles

The most essential command is the following:

First, create a temporary working directory: mkdir /tmp/workingBackupMediaFiles It is common to have files not being dumped out, due to errors caused by escape characters in File names. This will be resolved in the future. You must first go to the proper directory, in the case of standard PKC configuration, you must make sure you launch the following command at this location /var/www/html:

php maintenance/dumpUploads.php \
   | sed 's~mwstore://local-backend/local-public~./images~' \
   | xargs cp -t /tmp/MediaFiles

Then, compress the file in a zip directory. zip -r ~/Mediafiles.zip /tmp/MediaFiles

Remember to remove the temporary files and its directory. rm -r /tmp/workingBackupMediaFiles
