Partitioning external HD

[ehofmeister]

I am going to buy a Lacie d2 Quadra 1 TB external HD for my primary bootable backup of my mac pro, and I was wondering, are there any disadvantages to partitioning the large HD up in, say, three smaller partitons so that I can keep three separate bootable backups on the external HD?

Eg. One main backup of the system, and two "working" backups that I would then do every other week.

Is it safe to partition the drive up this way and use it for full, bootable backups?

The only disadvantage, as you might expect, is that if the drive fails you'll lose all three backups. Separating backups physically can be quite useful in that case.
