Sql-server – SQL Server database backup on Remote site

backupdisaster recoverysql-server-2008-r2

We have 4 different sites and each site has a SQL Server.

Our requirement is to have a SQL Server backup or database (Mdf files) of site 1, 2, 3 in site 4.

In case of disaster on any of the site we need most recent database of the site.

each of the site is connected in network with very limited bandwidth.
As the database size is more it is not possible to take complete backup every time.

For the above scenario can any one suggest me a better solution?
