Wait, how are you going to tier your storage to cloud? With some gateway! Here are some good players: Telstra Cloud Gateway (AWS, Azure, IBM SoftLayer, and vCloud Air), StoneFly Smart Cloud Gateway (AWS and any other S3-compatible cloud), StarWind VTL (AWS, Azure, Wasabi, Backblaze B2). Furthermore, you can use the public cloud as a second media, allowing you to save some money on NAS and disposable DAS. Both solutions are very affordable and have only hot tier offered for the price lower than Azure Archive Blob. If Backblaze B2 has any problems with speed in your region, try Wasabi! By the way, the latter can protect your data from malicious deletion or editing (say, by a vengeful employee). Speaking of cloud, here’s my “research” on this matter. You can easily extend your local storage there. If I were you, I would use the public cloud. Whatever solution is, it is vital to keep data on distance from each other: it is the only way to ensure their safety if your main site suffers. It can be a server in your remote location or public cloud storage. 1 copy offsiteġ copy must be sent as far as it is possible from your office. The later can be considered statistically independent too since it is connected over the network and may survive if something bad happens to a part of your infrastructure. Along with keeping a copy on a server, you can use some DAS (i.e., USB drive, SD-card, etc.) or NAS (if you have some money). That’s why you should always combine media. In other words, you may lose two copies in the same accident. The thing is, while keeping data on the same storage media, you may lose them due to the same hardware issues. 2 different mediaģ copies are to be stored on 2 different media. Furthermore, storing data in one box is not smart because if that thing gets ruined, all 3 copies are gone too. If one of them goes down, another dies soon too. Why does anybody need to store data like that? To make information whatever-proof! Keeping data on different disks inside one server or NAS box is risky because these devices are running under the same conditions and workloads. For instance, it can be drives of separate NAS boxes. You should also consider keeping these three copies on different devices. Following such a simple step will greatly increase information resiliency. Note that whenever I say “3 copies” here, I mean three copies of data excluding the original data! Create a primary copy first, and the rest need to be the duplicates of this one. Since the 3-2-1 rule is all about redundancy, you need to have at least three backup copies of your data. Here’s the 3-2-1 backup strategy in a nutshell. This being said, a good backup strategy is a sure way to protect your data from any malfunction, erroneous activity, or disaster coming your way. Just brace yourself for that, namely, do backups! Backups are good, but they may be useless without redundancy. Revolution, robbery, and simple mindless damage? Anything can happen, and you need to make sure that whatever misdeed or just bad luck comes into motion, your data are safe. Thus far, in order to protect your information, it is necessary to live with the mindset that sooner or later something may go wrong. Data, in their turn, weight too much for companies and people at large. It is absolutely true that today’s hardware and software are fragile. Why one does backups? To have a copy of data at hand if something goes wrong. Why Does the World Need a Rule Like That? I decided to write an article discussing this strategy in detail to make sure that guys new to IT will keep their data safe. Remember Blade Runner 2049, when people lost all their valuable data in The Blackout? Thanks to the 3-2-1 backup rule developed by Veeam, a disaster like that will never come true. Don’t risk it! Explore the 3-2-1 Backup Rule for ultimate protection.
