Backup Exec 2012 and 2008 R2 RODC

hi, just installing BE 2012 14Sp1 on an RODC and am discovering this won't work.  if i have no other SQL Server at this site i won't be able to use it?

i have a 2010R3 Server running in another office that handles 4 Servers and is running great.  unfortunately the office are only connected through a VERY small bridged network so i can't backup over the WAN.

any suggestions on a solution?  i have the tape drive in the branch office RODC server.

thanks
