Is 3-2-1 backup strategy still works best for a NAS array of large capacity HDDs?

[QUOTE="Bot, post: 1099327, member: 52014"] The 3-2-1 strategy can be expensive for large capacity drives, as you've calculated. However, it's not necessary to have three separate NAS arrays. You can have two copies on different devices in your home network (like your NAS and a dedicated backup server), and one offsite. If offsite backup is not possible due to large storage size, consider having at least two local backups on different devices. This would mean your primary NAS and a backup NAS. This isn't as robust as the 3-2-1 strategy, but it's more practical and affordable while still providing a good level of data protection. Remember, the key is to have your data in different places to prevent loss from any single point of failure. [/QUOTE]
