Synology network attached storage (NAS) devices are great for businesses. They enable easy collaboration, speed up restores, make your files accessible 24\/7, and give you a level of data protection you probably didn\u2019t have before. Essentially, a NAS device acts as a private cloud, offering centralized access and storage for everything from large files to ongoing projects.<\/p>\r\n\r\n\r\n\r\n

That\u2019s why it\u2019s important to back up your Synology DiskStation to the cloud. While NAS offers a layer of redundancy on-premises if you happen to lose files, it doesn\u2019t fully protect you from things like a natural disaster, a ransomware attack that infiltrates your backups, or multiple hard drive failures<\/a>. Cloud backups are important for data redundancy and future data recovery, giving you easy access and fast restores.<\/p>\r\n\r\n\r\n\r\n

To keep your data truly safe, the 3-2-1 backup strategy<\/a> is the industry baseline. Using a 3-2-1 strategy with your NAS means you keep three copies of your data on two different media<\/strong> (like NAS and cloud storage), with one stored off-site<\/strong>. Backing your DiskStation up to the cloud is a great way to achieve that key off-site element. This setup protects against various risks, and ensures your data is available for recovery.<\/p>\r\n\r\n\r\n\r\n

In this post, we\u2019ll explain how to implement a 3-2-1 backup strategy for your Synology NAS, the benefits of backing up to cloud storage, options for backing up your DiskStation, and some practical examples of what you can do by pairing your NAS with cloud storage.<\/p>\r\n\r\n\r\n\r\n

Synology NAS and a 3-2-1 Backup Strategy<\/h2>\r\n\r\n\r\n\r\n

The 3-2-1 backup strategy is simple and time-tested. If you are using your Synology NAS to connect and back up computers on your network, that\u2019s the first step\u2014you have two local copies of your data on different mediums. You\u2019d accomplish this by creating a multi-version local copy.\u00a0<\/p>\r\n\r\n\r\n\r\n

While this setup might seem sufficient, your data is still at risk from NAS device failure. It remains co-located with your primary data, making it vulnerable to disasters or theft. To fully protect your data, you need a third, off-site backup copy.<\/p>\r\n\r\n\r\n

For your third copy, you could back up your Synology to an external desFor your third copy, you could back up your Synology to an external destination\u2014either another Synology NAS, a file server, or a USB device. Each has pros and cons, and we\u2019ll talk through them for argument\u2019s sake.\u00a0<\/p>\r\n\r\n\r\n\r\n
