I'm using a disk-based backup solution but since the system in the article uses tape, the solution is the same. Take the weekend backup into work with you and bring the previous week backup home (actually, I use 3 sets so two are always off site). I tried a couple of online backup solutions but the bandwidth required to do the backups in real time was not available -- 3 days to do a full weekly backup didn't work for me.
depends on what you choose - the system I selected just uploads data changes (compressed) after the initial on site data backup which was shipped to the secure site. Changes are written to an SQL database to keep track of things. An Asigra based solution.
The differential backups with data de-duplication were fine. The problem is that I wanted a full bare metal backup as well. Stuffing the >1TB of backup data over the network was the issue. Since most of this was done as a part of looking at DR plans for work, I was wanting to find a solution that would scale well while keeping concerns about privacy to a minimum.
