Good questions. So today, the way the math works out is we can maybe fit 25 weddings on a 1TB we pick up for 80 bucks.. so that's about three bucks, six to do it twice. We think of it as a part of the cost of a particular wedding. You could charge me 10 or 20 bucks to archive before I'd even do the math. We likely spend more in gas for most weddings. Hell, I think each wedding costs us four dollars in business cards.
If you could get me to _really_ trust your service, I'd consider up-selling permanent archives to our clients. Lots of our clients would pay 50-200 bucks for the re-assurance, I'm sure. I don't know that I'd want the ever-growing liability though (right now we contract for 1yr of backup/online-gallery, but keep everything permanently without committing to doing so).
One time or yearly fee doesn't make a ton of difference to me, but with other services we've definitely been tempted into fixed "Unlimited" pricing so that we don't have to think hard about math, or end up tempted into picking and choosing what we backup. Simpler is better.. Managing a store of assets where some are backed up and some aren't sounds like a really bad accident waiting to happen.
Unfortunately, that math doesn't work out very well. If you were to implement it yourself, those numbers sound great. But to do it as a business, I think the math there is too cut-throat.
4 TB of usable space divided by 60 GB times $20 is $1,365. That's the kind of thing a consumer or prosumer could do on their own, but it would be pretty hard to make a real business out of it...
