Thank for this very helpful answer, which can be implemented for less than $100. For somebody who started working a
128kMac in the eighties, it is mindboggling that for that amount you can buy a terabyte of storage in a device that you
putin a coat pocket. I'll read up on rsync

performancewas almost as good as on my desktopc. But it cost hundreds of dollars per month. I work at home with a
machinethat has 32 GB of memory. In order to get comparable performance from a cloud-based Postgres instance, I'd have
tospend a lot of money that I don't have. Dropbox costs $120 a year for a terabyte of storage, which is very
affordable.
