That is exactly what it is. Plus making sure the network is provisioned with enough bandwidth to handle the extra copies, or even just the extra overhead. That's where Backblaze saves money, not purchasing "a few" servers, and only provisioning the network to handle the smaller amount of bandwidth required if you make a connection DIRECTLY from the client to the final storage Vault the data will stay on forever. Companies that have a networking, power, and computer hardware and spinning drive bill less than 2% of their total yearly company revenue often have PLENTY of ways of solving these problems for a "small amount of money". Backblaze is quickly approaching an Exabyte of customer data on more than 100,000 spinning disks. We have to purchase millions of dollars worth of hardware a month now. If Backblaze can solve a problem that shaves a few percentages of cost off then it can save quite a bit. Backblaze can then pass that savings through to customers.
