This is similar to my approach except that I don't use monotone, I keep
absolutley critical data in several formats on different media in
different locations (one copy to my parents for example).
Its the drive-on-the-shelf(-in-the-bank) issue I'm focusing on. What is
the best way to protect the data on that drive.
Since I use raid1 for my 80 GB drives, I can add that external drive to
the array to get a bootable snapshot, but is there a better way? Maybe
there's not but I figured that I'd check first.
As someone else noted, the data-security companies keep this stuff as
closely guarded secrets because its their bread-and-butter. If a
virtual-tape-server is no better than your own home-brew linux raid
setup then why spend the extra money?
