Hi from Paris, France ; so i apologize for my english ...
It appears that effectively not all files are available from W7 Recover, and that it may be deceived with system crashes (what ? it happens ???).

So i always use a very old version of SECOND COPY for that goal ; not so difficult to set up, il allows to be scheduled for example every night, and it achieves the most important recommendation about data security : make SEVERAL copies (versions) of your data, and on ANOTHER drive (than the saved one).

Even with 3 daily automatic saves, what about a mistake you made in a database or an accounting software 2 weeks ago ?
I also remember IBM's tips from when the PC (or MAC) did'nt exist... Take some time and space to also keep 2 special global saves : one let's say every 2 MONTHS, and one YEARLY, delays depending on your productivity.

Thanks for your great articles, mr Shultz !
