@roxie Is there really much risk? Very few ever go down suddenly, so there's virtually always an opportunity to fetch one's archive. (A good idea occasionally regardless, like any other backup)
But yes, if you actually want to run an instance, that's a different matter. Probably curable, though. =:)
@roxie Oh, gods - that's sounding like sysadmin stuff. Definitely work. Though for just one's own archive, a simple reminder every month or so would suffice.
