Several technologies support data backups, each offering distinct advantages: - Cloud Storage: Offers scalability and remote access. Providers like AWS, Azure, and Google Cloud are popular choices. - Network Attached Storage (NAS): Provides local storage accessible over a network, ideal for small to medium-sized businesses. - Tape Drives: Offer high capacity and longevity, suitable for archiving large volumes of data. - External Hard Drives: Easy to use and portable, but less reliable for long-term storage.
