[OPLINTECH] computer security

[Chad Neeper via OPLINTECH]

WRT Google Drive/OneDrive/DropBox/etc, keep in mind that these files sync
in "real-time" as you save changes to files. So only the latest version of
each file is kept easily accessible and synchronized across your devices.
If ransomware were to encrypt your data files, it would try to do it as
quickly as possible and all of the encrypted files would quickly be
synchronized up to the cloud and out to your other devices.

Google Drive and probably most of the others will retain older versions of
your files, so you typically CAN revert back to an earlier copy of the
file. But an important thing to remember is that you're going to have a lot
of files to revert back to. So think of your workload if you have to revert
every file manually. I don't think Google Drive has the option to revert
all files at once to a particular date/time. That's not really a typical
end-user use-case scenario for these types of services. I think you
generally need to do it individually for each file. I'm not sure about
OneDrive/DropBox/etc., but I expect they're probably similar.

So while you CAN use it as your life saver (and it's certainly better than
nothing), it may be impractical for lots of files. Something to think about.
