Best software for backing up over DSL line

Best software for backing up from freenas to freenas box over DSL line?

I have multiple freenas boxes and I want them backed up offsite over the DSL line to one freenas server so I am thinking replication is not suitable as I have multiple freenas boxes on the main site and only one freenas box offsite, so what would be the best way to achieve this.

Why not create a different dataset for each server on the system to hold the backups?
