A MakeUseOf article says the familiar 3-2-1 backup rule is missing a key step: testing restores. The writer found that backup files copied for months were corrupted, showing that having three copies on two media types with one offsite is not enough if the files cannot be restored. The article says Windows users should regularly restore a random file or folder, open it, and confirm the backup tool can retrieve it without errors. It also recommends keeping one immutable or air-gapped copy and treating verification as part of the backup plan.
