Keeping an up to date copy of a SQL Server database on another server [on hold]

We outsourced some of our business functions to another company. That company makes use of the same software as we do and we would like to keep a update to date copy of their database on our servers for monitoring purposes.

Just to clarify what I mean by having an an update to date copy we don't mind if the database is only updated or synchronized once a day.

Last thing to keep in mind is that the connection between the companies is a 10 Mbps connection.

We are both running Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64).

How would you tackle this?

Edit

I don't expect the database to grow to more than 8GB in the next 2-3 years.
