Subject: [PLUG] backing up RAID volumes under LVM--any sort of tool for this?

When I was installing our servers with ClearOS (CentOS derivative),
using LVM instead of the traditional partitioning method was presented
at the default. That and using software RAID 1 (mdadm) has made things
very difficult to understand now that I want to make images of them.

Is there any sort of tool that works well for duplicating LVM
partitions? GParted, for example, doesn't handle them.

In a slightly-related issue, I had the thought of backing the files out
of these file systems and loading them into non-LVM, non-RAID partitions
using rsync.
I have been using a rescue CD and the command:
rsync -avxHAX --numeric-ids --info=progress2 * /newroot
at the root level of the mounted source partition.

Is this liable to produce a working result?
