dumpUploads.php file is a maintenance script which dumps a list of files uploaded to a wiki. It can be used to create a backup of all uploaded files on the wiki.


Generate a list of uploaded files:

php maintenance/dumpUploads.php

Save all uploaded files to a tar file:

php maintenance/dumpUploads.php | xargs tar cf backup_files.tar

Copy to a temp directory, untar within that directory, and flatten sub-directories:

tar xcf backup_files.tar
find backup_files.tar -type f -exec cp {} . \;

This collection of files can then be imported into another wiki using the importImages.php maintenance script.


A list of available commands can be found inside dumpUploads.php, it is a generated list of uploaded files which can be fed to tar or similar. By default, outputs relative paths against the parent directory of $wgUploadDirectory .
