Eh, once it's set up the maintenance cost is minimal. Cron'd backups and such and you won't have to worry.

Yes I would consider my system optimal in terms of backup process etc. But I still tinker with it, try out new things, maintain the machines itself, it is a hobby. And it does consume time for me at least. But either way, I am sure a google pro subscription is still cheaper for me than the time value of setting up and maintainence, in the sense we are talking about saving money in real terms
