day, backup, swap, and so on.

OK

My question is: is this within the realm of plausibility, or would I
be tilting at windmills? I'm hoping to avoid a tape drive - high
capacity = high dollars, lower capacity = too dang many tapes.

Any suggestions for an alternative backup solution would be welcome.

First you must understand that the most importand thing of a backup is
the restore.

There are two kinds of backup. The first is where you make a copy so you
can place everything back. The upside is that you can do it prestty
fast. The downside is that you also backup the problem that might have
cause the reason for the backup.

The second is backing up data and doing this incremenal. This means that
you have e.g. 1 month worth of data to which you can go back.

With what you have you must first decide wich one of the two you realy
need. I personaly go for the second one. Why you might ask and the
answer is below.

As a restore is the most importand part, I looked at when I actualy need
to restore something and what I would like restored.
The main reason is because *I* am an idiot and delete stuff that I don't
want deleted. This concerns single files or directories.
Only in second place is actual problems with the HD itself. This means
that when something happens, with the HD, I would need to do a new
instalation, before I can put the data back.

However I only had a HD failure once, so for me having the incremtal
backup makes much more sense.

Actually, I was more concerned about whether or not it's feasible to
'hot swap' IDE drives; what I'm looking to back up is just the data -
not any apps or anything like that.
