[linux-lvm] Using LVM Mirroring to obtain a usable backup

[Ambrogio De Lorenzo <ambrogio de lorenzo alice it>]

Hi all.
I'm doing a big upgrade on my computer and I tryed to use lv mirroring
to obtain a copy of my data before to do it.

As I do with LVM on other OS i thought that after mirroring one could
chose to split the mirrored lv.

I can't find how to do it with LVM2 on Linux.

There is a way?
Tnx
 Ambrogio
