<p>This will perform a full restore of all PunBB tables from a saved file. If your server supports it, you may upload a gzip-compressed text file and it will automatically be decompressed. <b>WARNING</b>: This will overwrite any existing data. The restore may take a long time to process, so please do not move from this page until it is complete.</p>
