So backing up a terabyte for a year would be a $200 transfer cost plus $1800 for the rent. This represents 1 to 2% of the salary of a sysadmin, and sounds like a much better deal than buying hardware and hiring somebody to watch the RAID failures. Obviously if you have 100 TB, you get economy of scale.
One can also try to do data storage without paying, by getting an account at a national supercomputer center. But the problem is that every few months they will revise the purging policies, and you need to be on the ball with touching the data, renewal proposals etc etc. Also you need to maintain the client software that gives access to the remote data (GridFTP, SRB, etc etc).
I wonder who is intending to deploy a VOSpace that I can put my terabytes in and leave them there for ever.? Roy
