How to archive all reports on a report server

Hi,

I have an instance of 2008 R2 reporting services that is to be decommissioned.

Ive been asked to take a copy of all the rdl's on the server and archive them in case they need to be retrieved at a later date, but there are hundreds of them!

It would take forever to manually download them so I was wondering if there is a quick way to get them all?

Thanks,

Zoe
