The only real guarantee against data loss is not a magical recovery tool, but a good backup. The 3-2-1 rule is the gold standard:
- 3 copies of your data: The original + 2 copies.
- 2 different media types: Don't keep both copies on the same external drive. Use one drive and a NAS, or one drive and DVDs.
- 1 copy off-site: The Cloud. If there is a fire or theft at your home, this copy will save you.
