Yes, using active block-commit is the ideal way to perform a live backup.

libvirtd does not update VM .xml configurations on filesystem after virsh snapshot/blockcommit
Hi,
Recently We've upgraded some KVM hosts from Fedora 29 to Fedora 30 and
now experience broken VM configurations on filesystem after virsh blockcommit.
Commands "virsh dumpxml ..." and "virsh dumpxml --inactive ..." is showing diffrent configuration than the one on filesystem.
In case of restart libvirtd or system reboot, there are broken VM xml configurations on

Backup a VM (using live external snapshot and blockcommit)
Hi.
I'm following here a conversation that was initiated on Kashyap's
website [1].
We have a server we use as a host for virtual machines using KVM
(virt-manager used for VM creation) and we would like to setup VM
backups. Basically, we're thinking of a backup schedule like "keep 7
daily and 4 weekly backups". We'd rather not shutdown the VM every day
so live backups

Re: Ubuntu 14.04 virsh 1.2.2 blockcommit hangs at 100% / command 'blockcommit' doesn't support option --pivot
Dear Liam,
You need to upgrade to the latest LTS version of Ubuntu (16.04).
I refer to my message to this mailing list on 17/03/2016:
Hi everybody,
Following this user mailing list over a period of time, I saw a few messages regarding not being able using the external snapshot feature.

virsh blockcommit hangs at 100%
hi,
i am trying to blockcommit a external qcow2 snapshot back into its raw
backing file like:
sudo virsh blockcommit myDomainName vda --wait --verbose
the output just shows:
Block Commit: [100 %]
and stays like that (i waited about an hour or so...). No "Commit
complete" message.
- explicitly passing --base and/or --top arguments makes no difference.
- did not find a related log

Is virsh blockcommit supported? Thanks a lot
Hi,
I have another question, when I do the blockcommit command and get the result " Top image as the active layer is currently unsupported ", is it being developed?

I had test the command virsh blockcommit, but it failed, with the libvirt version 1.1.0, and qemu version 1.6.0.
Is this feature being developing? Thanks

virsh blockcommit fails regularily (was: virtual drive performance)
Hi,
a small update on this. We have migrated the virtualized host to use the
virtio drivers and now the drive performance is improved so that we can see
a constant transfer rate. Before it used to be the same rate but regularly
dropped to a few bytes/sec for a few seconds and then was fast again.
However we still observe that the following fails regularily:
