Hi, I am using Lucid 10.04 64 bit. I had created some lvms in some locations on my server. Which I am not able to recall. pvdsiplay lvdisplay

So how do I take backup of these and how do I find out what will be the size of hard disk required to take backups. If an LVM image is 100Gb so do I need 100Gb space in my hard disk to take backup. Or how is the process of backup done when I have LVM based images? -- Tapas -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
