No news on that from VMware for 2 years now... I am starting to think this may simply be an impossible limitation for them to overcome (just like some other current limitations of FT).

[MERGED] How to Backup Fault Tolerant VMs in vSphere 4 (and

Veeam Logoby trafsta » Tue Oct 09, 2012 4:36 pm

So unfortunately it appears that I am one of many to discover that VMWare Fault Tolerance VMs do not allow snapshots and therefore Veeam (and other snapshot-driven backup solutions) cannot backup FT VMs. That said, I read this article:

How to Backup Fault Tolerant VMs in vSphere 4
http://www.petri.co.il/backup-fault-tolerant-vms-vsphere-4.htm

And was wondering if anyone has attempted this and would care to comment on their success with it. I think I am going to attempt it. We are a Hyper-V environment which just purchased our first two SANs (EqualLogic PS4100XV/E) and we are in the process of migrating to VMWare vSphere v5.1 so we have hit a few bumps along the way but for the most part this is the last thing we have to overcome (FT backups).

Essentially from what I gather, if you backups start at say 8pm, you have to use Windows Task manager to 'turn off' the FT on the FT VMs (not just 'disable') a few minutes before the backups start via a script (vSphere CLI), and then Veeam will back them up correctly, afterwhich you can have a "Post job activity" in the Veeam job to start a batch file that launches a script via vSphere CLI to turn FT back on for whatever VMs you require.

Messy? Yes... but hopefully this allows us to have the best of both worlds (we are for the most part a 9-5 shop so if I can have FT turned on from 9-5 and just disable it during the 2-5hr backup window each night then I am happy with that).

Please share your comments and experiences on this :)

Oh, also, I found this interesting from the article above: "...if you are using a third party application such as Veeam and have an active support agreement with the vendor, then you should contact them first to see if they have their own solution." I haven't *yet* contacted support on this as I suspect they don't have a Veeam-supported or endorsed solution (at least none that I have seen via Veeam Forum searches) but perhaps I will contact them when time permits...

Pardon my self-promotion, I recently wrote about the same topic on my blog, if you want to read it:

Just a note about my post two posts up. I have set this up on my Veeam server and it works quite well (disable FT via task scheduler scheduled vSphere CLI [Perl] script, Veeam B&R does its backup, Veeam post activity reenables FT). Too bad Veeam doesn't have a "Pre job activity" in addition to the "Post job activity". Hopefully this is on their todo list for future feature requests (I wonder where the best place is to request feature requests for Veeam V&R? By opening a support ticket?).

On a side note I read this on Luca Dell'Oca's (post above this one) blog:
"During the last VMworld US 2012, VMware showed the future version of FT, that will allow multi-processors and snapshots"

So hopefully this workaround will only be necessary for another 3-6 months or so... beeing new to VMWare I don't know how quick they are to release new versions (especially new major version releases, once a year or what?). But I guess time will tell...

Well, it's a "technical preview" so basically there is no guarantee even this feature will be implemented at all, but for sure customers' requests are huge sinec day1 they launched the actual FT, so for sure they are working on it; they told me that, simply put, is not so easy at all to do it.

Right on these forums. Consider this one is already filed. :)

[MERGED] Veam cannot backup the VM even though the FT is Dis

Veeam Logoby tikitiboo » Fri Mar 07, 2014 2:38 pm

Hi,
I have few VMs on a fail over cluster and trying to backup a virtual machine using veeam but its says
Task failed Error: 'virtual machine name ' ('vm-71') cannot be processed: fault-tolerance enabled.

The thing is FT already disabled!

Many Thanks

You cannot backup FT VMs, please see above for possible workarounds.

The problem is even though I turn off the FT I get the same error!
Task failed Error: 'virtual machine name ' ('vm-71') cannot be processed: fault-tolerance enabled.

Just to clarify, are you turning FT off completely or just disabling it?

Yes, this is expected. FT should be disabled completely to create a snapshot.

Then I suggest contacting support so they could verify your environment and probably suggest the reasons of this behavior.
