I asked the same question a few posts down and was told that taking a snapshot of a running system could lead to some corrupted files. I recommend you look for "[Xen-users] Xen backups using LVM Snapshots" and make your own decision from there. Best of luck. -- eco ----- Original Message ----- From: "Aleksandar Ivanisevic" <aleksandar@xxxxxxxxxxxxx> To: xen-users@xxxxxxxxxxxxxxxxxxx Sent: Thursday, October 16, 2008 12:48:47 PM GMT +01:00 Amsterdam / Berlin / Bern / Rome / Stockholm / Vienna Subject: [Xen-users] Re: Xen, LVM and snapshots "Morten W.

Is it safe? It is safe, but be aware that the mere fact that you have a snapshot active can slow down write speeds to the volume by a factor of 10. I got bitten by this, but I also have DRBD in play, so I don't know for sure if its a xem, drbd or lvm issue, or the interaction between the three. -- To sto si frustriran, zavidan tko zna na cemu i sto ne vidis dalje od svoje guzice je tuzno.
