I've been running a non-production oVirt setup for a while and plan on
building a more robust oVirt setup for eventual production use. Part of
that planning of course is backup/disaster recovery options.
I've been playing around with a few options to backup oVirt, I'm sure most
of you are aware of them. The github webfix it python scripts, and
starting to look at bacchus as well although have not set it up or tested
bacchus yet.
The webfix it python script is fairly simple to setup and seems to work ok
as intended, even on 4.2, but it's definitely clunky in terms of having to
snapshot, clone, export. A lot of resource usage. I assume bacchus most
likely uses the same method of snapshot/clone/export as well (due to what
was available in oVirt at the time these scripts were written).
My concerns with using something like these are:
1. It's using old 3x api -- which is fine for now but probably not with
oVirt 4.3
2. Inefficient / resource intensive
3. Using export domain which is depreciated
From what I've read in oVirt documentation the Export domain is
depreciated. I assume that this means that instead of a export domain you
could instead create a regular data domain for backups that can be detached
and attached to another environment, is that the correct assumption?
I've also read that it might be possible to skip the cloning of the VM part
and export snapshots directly. Is this now possible in 4.2 or will be in
the future? if it is possible to perform VM backups without cloning to a
new VM first is anyone aware of any scripts/software that is available now
which takes advantage of that?
Essentially all I want is a simple solution to backup my VMs to separate
NFS storage. If for some reason my main storage crashes I then have the
option to connect that backup NFS storage to a secondary stand alone oVirt
instance and run my VMs from there until the primary oVirt instance is
repaired. What I want to avoid is implementing an older more inefficient
solution that might work for a while but will eventually no longer work due
to ovIrt updates in the future.
I know options like active-active failover and georeplication exist but
that may be too complex for my needs although I would be interested in
hearing about how some of you may be implementing these features.
In summary, I'd trying to figure out what the best backup option may be
going forward with oVirt in the future so I can implement the best option
from the start rather than having to change it all around in the near
future.
Thanks!

If you are using NFS, you might find it easier and more efficient to use a
solution outside oVirt.
I've documented an initial attempt at backing up machine images with backy2
at
https://dyasny.blogspot.ca/2017/06/exploring-backup-options-for-rhvovirt....
It is harder to do with block storage and frankly I haven't had the time to
get to doing it there, but NFS is simple enough, and what you get is pretty
robust, deduplicated backup, in some ways similar to the typical VM backups
you get from Veeam and Altaro on other platforms (sans the GUI of course).

Indeed, to be a proper solution it requires some work, my old blogpost was
about the initial testing of an external backup solution, which can keep a
consistent set of deduplicated and ordered backups, quite easily restorable
to a PIT, just like you have with many of today's hyper-v and vmware
solutions. What it missing is crash consistency (an API call is required to
qemu-ga and other scripts), VM configuration data (OVF or DOMXML export of
the VM itself, not just the disks), snapshot chain preservation (not sure
it's much of a requirement in a backup solution).
The oVirt backup API is nice, but what it gives you in the end is a full VM
image, instead of incrementals, which is a huge waste of space, unless you
are using deduplicated storage, and those are too expensive to store data
at rest usually.
What I like about backy2 is the fact that it deduplicates on the fly,
without using anything too low level like ZFS, and you only store the
diffs. It also works at the block level, so LVM volumes and files on NFS
are treated the same. The extra features like bitrot prevention and NBD
aren't without use as well. I'm sure with some work it can be made to work.
I've also been looking into a very different approach, e.g. live-migrating
the VM memstate and disks into a backup image, with migration cancelled
when sync is achieved, but that required some serious support from the KVM
folks and I had no time besides a shallow dabble.

I'm still deciding on storage solutions and have not made up my mind yet.
GlusterFS may be an option but I'm not sure about performance and
maintenance. It sounds to me like GlusterFS with secondary replicated
gluster volume would work quite well as a disaster recovery solution but
I'd also need historical/incremental backups as well, either of the VMs or
at the very least some important files within such as production DBs etc,
which may be possible with a secondary backup method using rsync or
something along those lines.
It seems to me that there is not a great backup solution for oVirt yet
which I find hard to believe. I don't understand why backing up oVirt VMs
has to be so complicated, compared to other products. I was hoping that
4.2 would change that and allow for easier more resource efficient backing
solutions.

Gluster has a geo-replication based backup which is very cool and

It seems to me that there is not a great backup solution for oVirt yet whic=

I've been playing around with a few options to backup oVirt, I'm sure most =

The webfix it python script is fairly simple to setup and seems to work ok =
