  • You are trying to solve two different, but related problems, and there are discrete solutions for both.

    One is a personal cloud. You need a secure place to store your shit from multiple users and devices, from multiple networks. You’ll need a mostly static IP and dyndns or your own domain, and certificates signed by a public CA/letsencrypt.

    Then, you are looking for a backup application that supports rsync or sftp/scp over ssh or vpn, that is also cross compatible (Android and PC/Linux). Point this to the service above, and you are good to go.


  • This.

    At some point, you need to be able to quantify the risk to your business before you can do this.

    For instance, if your business earns $10 per transaction, and you perform 100 transactions per second, the difference between five and six nines (313 seconds vs 31 seconds) is $282,000; nowhere near enough to justify the added investment.

    Edit: Important to note that for the first example, these are already enormously huge numbers. Such a business, assuming no holidays or weekends, would be grossing $31.5 billion per year, in the same ballpark as Oracle and Coca Cola.

    So when we say the company is losing 282,000, this is a tiny, tiny fraction of revenue. Even 99.5%, which is almost two days of downtime, would “only” be a loss of 0.5% of all revenue for the year. Sure, this is $157M, but even that would probably not cover the cost of a six nines infrastructure (that said, they could save up to $120M per year by achieving 99.9%, which would be worth exploring).
