You can get around this limitation to a degree by cycling in another drive
or two (hot swapping is a nice feature for this). For example, get a third
drive with just a HD carrier (no frame) and simply rotate the drive through
once a week or so, so that one is always off-site and contains a working
drive. That way if a virus or corrupt file screw up your operating system
you can always fall back on an older version. Mind you, in this case you
could still lose a weeks worth of work. However, in my experience, this is
very unlikely if you exercise just a minimum of diligence. For example,
before you install any new software or Service pack, take the mirror drive
off-line, install the software, check it out and if everything works well
simply put the mirror drive back online and it will be rebuilt in the
background.

Keep in mind that RAID 1 protects you from a HD failure, but is not a
substitute for regular backups. Example... let's say you contract a virus or
hose-up some files. Guess what... now you have a nice mirror of two drives
with viruses or hosed file ;-) Now.. if you have a tape/zip/CD/disk backup,
you can restore your system/files from a time before they became toast.
Also.. if you value the many man hours of work you've invested in creating
systems, data, whatever, and this data is stored solely on your HD(s), then
you'll also want to store a copy of this valuable data ( on some sort of
removable media) off-site. Fires and theft happen. Don't have all your eggs
(data) in one location.
