Hi,
Thanks for posing this question. Your approach is a viable option, but I'd
be more inclined to use a file backup set for the sake of continuity and
security. You'd be treating the drives as removable disks, while they're
meant to be fixed media, and as such you have to rely on the drive mounting
for integrity of the backup set. If you should lose your catalog for
instance, and the drive does not mount properly or is not recognized during
the recatalog, your entire backup set may be unusable.
A more reliable method would be using each drive as the destination for a
file backup set to which you would perform incremental backups. While this
still leaves you with three backup sets and three copies of your data, as
neither file backups nor duplicates can span volumes, I recommend having
more than one backup set in any case. This method could easily use media
rotation, or better yet a backup server script could be designed so that
backup happens to whichever drive is connected when the script starts.
If you are concerned about space, of course, you could always segment your
backups so that different data is stored on each drive. For example, you
might have your system on one drive, personal data on another, and work
material on the third. This allows for incremental backups without being
redundant.
Hope that helps!
