Oh and by the way, after the dd is finished you can lvremove the snapshot file. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Geofrey Rainey Sent: Friday, 24 July 2009 9:16 a.m. To: General Red Hat Linux discussion list Subject: RE: backup system for RHEL I use Xen snapshot like so: 1. create a snapshot file - this can probably be quite small (depending on usage but 1G is probably enough) lvcreate -s -L 1G -n <name of snapshot> /dev/<volume_group>/<logical_volume_name> 2. then backup your partition with something like this: dd if=/dev/<volume_group>/<name of snapshot> of=<path/lvm_backup.img> bs=1M 3. if you need to restore, do the following: dd if=< path/lvm_backup.img of=/dev/<volume_group>/<logical_volume_name> Of course you'll need as much space as the original partition for this but that's the only solution I think. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of ESGLinux Sent: Friday, 24 July 2009 12:46 a.m. To: General Red Hat Linux discussion list Subject: Re: backup system for RHEL Thanks for your answer, I´ll take a look at openfiler, it looks great.
