The Synology NAS DS214se is perfect for those wishing to have a reliable backup of all files. Affordable (naked cabinet) easy to start. The interface of the software is DSM5 ergonomic and practical for server management, although it is not always easy to set certain functions. No user guide, but help on Synology website is well done. It's perfect for family use and will help keep your data safe from any incident. I do not put 5 stars because a notice would be welcome. I highly recommend it.
