how to test incremental backup in 4.4
Hello, going to test incremental backup in 4.4. Is this page the updated one to use: https://www.ovirt.org/develop/release-management/features/storage/incrementa... ? Is there already any ansible module/role ongoing to support it? Thanks, Gianluca

This page contains a lot of data about the feature and includes must of the APIs but it still needs some updates. There is currently no up-to-date documentation but we are working on it.

There is no Ansible implementation for it but we provide a python SDK script for backup a VM using incremental backup new API [2] [1] - https://www.youtube.com/watch?v=foyi1UyadEc [2] - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_vm...

Also, please note that in order to use the incremental backup feature you must set 'IsIncrementalBackupSupported' to 'true' in the Engine database and restart the engine before taking a backup - engine-config -s "IsIncrementalBackupSupported=true"

Do you mean from RH EL 8 point of view or upcoming RHV 4.4 (now in beta) point of view or the two upstream projects themselves point of view? Gianluca

Just the first steps. I enabled in engine the incremental backup feature and restarted engine service. Created a CentOS 8.1 VM to backup, and updated it.

I could be wrong but i believe you need to push libvirt / qemu to a newer release on your hosts to enable the feature. This may be a 4.3 only thing though. On 9/6/20 6:21 pm, Gianluca Cecchi wrote:

I have no idea the version numbers, i'm just referring to comments in the example backup_vm.py script Note that this feature API is supported from version 4.3 but the feature is currently in tech-preview until libvirt will release official release that contains the support for incremental backup. Using this example requires a special libvirt version supporting incremental backup. Given that previous poster also said its 'still' in tech preview on libvirt/qemu side, I assumed you might still need a special version of libvirt to enable the feature. ------------------------------------------------------------------------ *From:* Gianluca Cecchi [mailto:gianluca.cecchi@gmail.com] *Sent:* Tuesday, June 9, 2020, 6:49 PM *To:* Joseph Goldman *Cc:* users *Subject:* [Possible SPAM] Re: [ovirt-users] Re: how to test incremental backup in 4.4

Too old, you need RHEL 8.2, best RHEL 8.2.1 nightly build. Using ovirt-release-master.rpm: dnf install http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm You should get newer enough libvirt and qemu on CentOS 8.1, but it is not tested with incremental backup. It should work on Fedora 30 host, but Fedora 30 is EOL now. New enough libvirt and qemu are available in Fedora 31 and 32 (using virt-preview repo), but installing oVirt there is a challenge and I don't think anyone tested it yet.
Possibly needed sw pieces will be only in 4.4.1?
4.4.1 will include important fixes and new features in oVirt, but it will not help with libvirt and qemu. Nir

Try it.
So probably, remaining in CentOS, we will be able to test with a combination of 4.4.1 + CentOS 8.2? I will keep track of this: https://wiki.centos.org/About/Building_8.x#Current_Timeline_8.2.2004 and when the node image will be based on it.... Gianluca
Hopefully yes, just validate that the libvirt version is >= 6.0.0. On Wed, 10 Jun 2020 at 11:07, Gianluca Cecchi <gianluca.cecchi@gmail.com> wrote:

I could be wrong but i believe you need to push libvirt / qemu to a
newer release on your hosts to enable the feature. This may be a 4.3 only
wrote: thing though.
I have 4.4 and currently on host: qemu-kvm-4.1.0-23.el8.1.x86_64 libvirt-daemon-5.6.0-10.el8.x86_64
Too old, you need RHEL 8.2, best RHEL 8.2.1 nightly build.
Using ovirt-release-master.rpm: dnf install http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm
You should get newer enough libvirt and qemu on CentOS 8.1, but it is not tested with incremental backup.
Should work also with RHEL-8.2 (libvirt >= 6.0.0)
Try it.
So probably, remaining in CentOS, we will be able to test with a combination of 4.4.1 + CentOS 8.2? I will keep track of this: https://wiki.centos.org/About/Building_8.x#Current_Timeline_8.2.2004 and when the node image will be based on it....

It is always better to use the latest version for testing this feature. If I remember correctly 4.2 contains some fixes for incremental backup so better to use it. On Wed, 10 Jun 2020 at 11:28, Gianluca Cecchi <gianluca.cecchi@gmail.com> wrote:

While do you confirm that Qemu 4.1 vs 4.2 is not essential for the feature?
