Datto devices come with a 3-year warranty (5-year warranty for Datto SIRIS 5) that is fully covered as long as the service is active and being paid. You can purchase an extended warranty. After the warranty expires, Datto will continue to support the device and host the data off-site as long as the service is paid, but the device will no longer be covered by warranty. If the device fails, you can purchase a new one and Datto will pre- load your data at no charge.
