If you want simple cost effective self provided, self managed off site backup, then look no further than the ReadyNAS range of storage products from Netgear.

All ReadyNAS systems include multiple backup layers that you can customize to fit your needs. First, protect Windows and Mac clients with the included CDP software. Then, backup to a USB drive on demand or on a schedule. Replication is a cinch between two ReadyNAS systems, and finally the ReadyNAS Vault option can move files and folders to an offsite secure data center for disaster recovery. It’s all built in!

The ReadyNAS NVX Pioneer Edition is Mac-friendly, supporting Apple Filing Protocol (AFP), allowing native Macintosh® files to be used without limitations. It also supports Apple Time
MachineTM, so multiple Mac users can now back up to a single centralized, secure, high- performance network storage device and recover data with ease. Apple’s Bonjour® software technology enables auto-discovery of a device over a LAN and Macintosh status monitoring widgets are supported.
