Big dilemma: data protection with Knox (sparseimages) / back up with SuperDuper!

[gianfry]

Thanks dnanian, for replying.

Mmmh, about PNG: it looks fine, but I don't feel like researching any longer, for the time being.

So, knowing that I want to use SuperDuper! to produce a backup on a sparseimage (and on a whole-disk vault, probably), could you tell me what would be the best procedure to boot my copy if I never need to?

Options I think of:

- Partitioning the Backup Disc leaving an encrypted partition, so that I can copy the "bootable copy" to that partition which is not encrypted, and boot from there.

- Partitioning the Backup Disc leaving an encrypted partition, and make a copy of the OS X Install Disc on the uncrypted partition of the disk (which take less space than copingy the whole "backup copy"), so that I can boot from there and… actually I don't even know what you exactly do with the OS X Install Disc, if ever your computer disc craches…

Anyway, confusion, confusion…
