Hi all,

just to add some ideas to lvm snapshots.

As far as I know ist there no need to dd the hole disk. It should fit if you
just make the lvm snap ant mount it to any device you want. So you could pack
the hole img and store it via bacula or something else. And you normally dont
need to shut down the system. The snapshot tooks a bit longer but should even do
it while the system is in use.

So just:

- take the snap
- mount it
- pack it

Dont hit me if i am not right :-)
