I haven't read it all yet - to learn about the actual technology they're using - but the statement
"....with this system you have constant back-up a millisecond after you create the file."
would seem to be erroneous, since the file needs to be written to HDD first, and SAVED to HDD/ODD/NAS, whatever - rather than "created". Disk Cache settings, like write-behind caching come into play here
yes - it may be nit-picking , but when backing up data is concerned (especially when you're talking about a virus executing code and propogating) - you better be precise in your statements (actually in most hardware reviews, I would apply this standard) . Like when a trusted reviewer refers to the newer USB wireless transfer rate as MBps, when it's clearly mbps -- that reviewer needs a new proofreader, or should be let go.
I could be wrong, if it's taking a snapshot of your memory - and if that's the way it functions - perhaps big bro has finally teamed up with AV software companies, since good AV software needs access to every part of Disk and Memory.
just some quick observations
