Datto earned a round of golf claps with its Backup NAS by bringing comparatively affordable off-site storage to the small businesses of the world, but it's giving itself a round of applause with the Z Series. Hailed as the "planet's first on and off-site backup solution to use ZFS," these units provide up to 1TB of local and off-site storage, optional RAID 1 local redundancy, twin gigabit Ethernet ports, OS X / Windows / Linux compatibility and the obligatory rock-solid stability that ZFS is known for. You'll also get a rapid recovery promise, which enables you to sleep easy knowing that your data can be restored within 24 hours should disaster strike. The units range in capacity from 250GB ($499) to 1TB ($1,149), while the required service packages demand anywhere between $35 per month to $1,000 a year.
