JBOD allows the two or more drives to be used independently to increase storage capacity. The downside of this configuration is that data access is slightly slower than RAID 0. RAID 1, on the other hand, writes data to one drive, which is then copied to the second disk drive in a configuration called mirroring. But since the data is written across multiple drives, there’s no redundancy if one of the drives fail. RAID 0 is where data is written across multiple disk drives, which increases performance.

The main three RAID configurations that apply to photographers and videographers are RAID 0, RAID 1 and JBOD (or 'Just a Bunch of Disks'). It uses two or more HDDs or SSDs to provide performance increases when accessing data, or to provide redundancy in the case of disk failure. RAID (Redundant Array of Independent Disks) is a system that can be found in some hard drives and NAS (Network Attached Storage) drives. We've highlighted some of the best examples of those in our 'best local photo backups' section below, but if you already have one you can skip down to the 'How to back up Google Photos to a hard drive' section using the menu on the left. And if you use Google Photos as your main image storage, this can also be combined into the 3-2-1 strategy by keeping a local backup on an external hard drive. Whether you’re a working professional or a keen amateur photographer, the 3-2-1 strategy is a no-brainer because it means that you’re highly unlikely to ever lose access to your images and data.īacking up your raw and editing files is obvious, but you'll need to backup your Adobe Lightroom catalogue too, because this is where all of your edits are saved. Also, no cloud storage provider is immune to outages – so while cloud backups are an essential part of the 3-2-1 strategy, you'll still have your local backup available should your provider suffer an outage.
