Actually, this is good enough for what I need: I'm planning to offer backup space to customers. So I will start with an x Gb HD (vinum'ed, of course). When I sold the whole of it, or I'm about to do it, then I will add a new one. The trick is that there are very high chances that when I've sold x Gb of backup space, the real used space is y, being y << x, so basically I'm adding disk space when there is a lot of space available still. Will that suffice, or am I lying somewhere? Thanks! Fernando P.
