The one thing that has put me off Tarsnap until now is, and not to be intentionally morbid, the bus factor [1] of 1. As far as I know its just Colin that runs it. In the unlikely event we need to access our backups, tarsnap is down and Colin is no longer available to maintain it we could be stuffed.
Colin, do you have a contingency plan in place if you are not available?
