Multiple Locations but slow links

I am using Backupexec 2014.   We have one media server but I am trying to understand how and if this will work.

We have a filer server running BE 2014 as the media server in location 1.   BE runs fine to the local storage.

In location #2  we have another file server and a local NAS.  The WAN link between the sites is sort of slow vs the amount of data.   Can I setup a backup to disk in location #2  that will backup to the NAS also in Location #2.   I want to do this without all the data going across the WAN link.   But of course I want the media server in location #1  to monitor it all.

I am guessing I need another media server although no budget.

Thank you,
