Glacier is not a cheap/viable backup

its even less suited to disaster recovery (unless you have insurance)

Think about it. For a primary backup, you need speed and easy of retrieval. Local media is best suited to that. Unless you have a internet pipe big enough for your dataset (at a very minimum 100meg per terabyte.)

4/8hour time for recovery is pretty poor for small company, so you'll need something quicker for primary backup.

Then we get into the realms of disaster recovery. However getting your data out is neither fast nor cheap. at ~$2000 per terabyte for just retrieval, plus the inherent lack of speed, its really not compelling.

Previous $work had two tape robots. one was 2.5 pb, the other 7(ish). They cost about $200-400k each. Yes they were reasonably slow at random access, but once you got the tapes you wanted (about 15 minutes for all 24 drives) you could stream data in or out as 2400 megabytes a second.

Yes there is the cost of power and cooling, but its fairly cold, and unless you are on full tilt.

We had a reciprocal arrangement where we hosted another company's robot in exchange for hosting ours. we then had DWDM fibre to get a 40 gig link between the two server rooms
