I would ask you to consider also the effort in recovering if you don't have good, current backups stored in another site if you lose your building. Moving media can be tedious, but the alternative could be very costly, as either you have some remote replication in play or you lose everything.

Whilst backup to another local server will give you options to recover with if you damage your server somehow, such as accidentally deleting some critical data, you need to consider how you will recover if you lose access to the building too, balancing what is acceptable against the cost.
