Oh dear what a mistake getting this one.
I have over 20 years in IT and I have seen a few poor products. The product is good what is letting this model down is the more advanced features, Netgear seem to think they can get away with the simple answer of, this feature is no longer supported but if you install ssh addin you will find more features here, note ssh is not supported by Netgear and we will not help you if you do install it,
It worked out of the box sharing files yes, pushing backups, forget it, changing user rights after backup forget that one as well doesnt work, admin rights over all files, No, not unless you install the unsupported ssh,
Ftp no way, tec support sorry please use remotenas, oh my lord it was so slow I just laughed,
I can not comment of the raid side of things or the support of squeeze server,
Netgear seem to have confused alot of people with the naming of this item as well as its a new product since nove 2011 with a similar name to an older product that had more features,
if you have good linux skills you will love it if not stay way unless you just want simple sharing,
Money back? I doubt it, just an expencive networked hard disk,
Come on Netgear you need to sort out the very poor backup software.
A better manual as well with better examples.
