I'm curious - how much space does the online index take up?  I'd
imagine that it would be proportional to the number of files backed
up, which might be hard to estimate...

I'd swear that I've heard people throw around figures like "10% of the
amount that's backed up", which seems absurd.  In our case, since we
have about 160 Gb on tape at the moment, we're talking about an online
index of 16 Gb using that ratio...yow!

Does anyone have more accurate estimates (especially based on real
experience) for products that maintain a complete online index?
