The best NAS upgrade isn't another drive, it's fixing your backup plan first

Adding more drives to a NAS is not a substitute for a real backup strategy. RAID protects against drive failure but not against human error, ransomware, or disasters. The 3-2-1 rule — three copies, two storage types, one offsite — is the recommended approach. Practical steps include scheduling automatic backups to an external drive, using cloud services like Backblaze or Amazon S3 for offsite copies, enabling snapshots and versioning, and keeping at least one backup immutable or offline so ransomware cannot reach it.
