![]() This is what the 3-2-1 rule covers, and i don't think you understand that. You need to justify your solution in two ways:ġ: If i get hacked, and they get access to every network attached component, server, etc - where is the backup then? Is it in the cloud using locked azure storage blobs with recovery? Is it in a safe? (as was mentioned)Ģ: If my building / infrastructure catches fire, or any other possible disaster, is the data somewhere else? ![]() It is extremely common for this to cause a chain reaction of failing drives, so no - it is far from zero chance of happening. When one fails the array goes into fault tolerance mode which puts a higher strain on the remaining drives. What happens is that you have 4 (or 8, or n) drives in the raid array. This is where having an inbuilt or san tape drive would work really well, but it does not matter - you can choose a NAS or a tape drive.Īlso, if you were somewhat experienced in this field you would understand that disks due in fact start to fail at the same time, so your 'zero chance of that happening' remark simply shows your ignorance in the matter, which is why you asked for help, and is why you shouldn't be so hostile to those giving you help who actually know what they are talking about. ![]() Secondly, in your specific scenario as pointed out, you want to avoid having to transfer that amount of data between devices / networks due to it's sheer size. Not what media is better or why - it's a rule that protects your data. So you need to take the advice pretty seriously that you're breaking the number one rule of backups, the only important thing. What specific media you use to follow that rule does not matter one bit, it could be tape drives, usb drives, cd rom, hell you could print the blocks out in binary onto paper for all i know. Now, because of this and the fact that it was popular early on, the tape technology evolved to a point where there are thing like automatic feeders etc, but that's just an evolution of the tech.Īs u/cmwg pointed out, the fatal flaw in your proposed solution is failure to follow the 3-2-1 rule. We're talking 100s if not thousands of years when stored properly. To answer your question very, very specifically - tape's main and only benefit over other media is that it is very, very hard for that data to degrade over time. First i want to say you probably shouldnt be posting asking for answers / advice if you're just going to be a dick and argue with people trying to help, but whatever.
