I think what you’re looking for is LVM snapshots. The whole purpose of taking VM snapshots is to have a consistent image of the machine as a whole. There’s lots of articles out there on LVM snapshots, here’s one.

snapshot-create-as for a single disk not all disks
Hi everyone!
Is there any way to create snaphot for a single disk of a virtual machine. As I konw, "virsh snapshot-create-as domain_name snapshot_name --disk-only" traverses all block devices to create snapshot. However I don't want to create snapshot except for root partition.
The version of qemu and libvirt I used is as follows:
qemu-1.4.2 and libvrit-0.10.2

imaging a drive with dd
...rfs, they only affect the RAID-5/6 features. You don?t need that here, so you should be fine with btrfs.
And if you really distrust btrfs, ZFS is easy enough to integrate into CentOS on-site.
And if *that* is also out of the question, you have LVM2 snapshots:

Why reinvent the wheel?

imaging a drive with dd
I am building a mailserver and with all the steps, I want to image the
drive at various 'checkpoints' so I can go back and redo from a
particular point. The image is currently only 4GB on a 120GB drive.
Fdisk reports:
Disk /dev/sdb: 111.8 GiB, 120034124288 bytes, 234441649 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

This is Centos7-armv7. Not all the tools are there. I keep getting
surprises in some rpm not in the repo, but if I dig I will find it (but
php-imap is NOT built yet and that I need).
The base image is a dd, and you start with something like:
xzcat CentO...

Xen backups using LVM Snapshots
Hi all,
I am running Xen 3.2-1 / 2.6.18 on Debian Etch (Dom0).
I setup a Dom0 with several DomUs (Linux). Each DomU disk is a LV partition. I have been seeing a few mails about backups and LVM and just wanted to make sure that what I am doing is correct.
Each DomU with a database has a cron that dumps the db with mysqldump. Later on, Dom0 will do an LVM Snapshot of all DomUs and then do a
