Add another to the Nutanix camp. Really wish Veeam supported CBT on SMB 3.0 from Nutanix. :)

Hi,

Drop me an email!
Always good to have a fellow Nutanix user to talk things through.

An alternative is to coöperate with Nutanix and have the ability to read out their snapshots and export them to a library.

There's another backup vendor that has been working closely together with Nutanix in order to achieve this.

Kind Regards,

I believe with Windows Server 2016 release support for non-windows SMB shares will not be needed?

According to my non-official information that's correct.
Microsoft will have its own CBT mechanisme like VmWare.

RCT -> Resilience Change Tracking I believe.

So basicly, if you wait long enough...problems get fixed ...

Cause you'll need to approach your backup in a scaled out thinking way...

Nutanix and Veeam wrote a best practices, but i'm not 100% agreeing with it :-).

I allow my backup to handle multiple vm's per repository but then limit the number of vm's / host that can be handled.

This way i'm sure it's taking a backup of vm's that are spreaded over hosts (read storage with Nutanix) and get some good speeds.

Are you running Hyper-V on the Nutanix or VmWare ?
I run Hyper-v, but advice VmWare.

drop me an email : bjorn.lagace@terbeke.com with your config on both nutanix/veeam/repository environment and what you wish to achieve.
I have almost a year experience now with debugging and optimising this :-)


How are you getting your jobs to limit the number of VMs per Nutanix node so that you can get enough streams going? I too am trying to squeeze everything into my backup windows since the lack of CBT has us reading all of the data nightly.

I agree with you as well.
The best practice they wrote (which I've seen before it was released) is not the best imho.

I have a readout peak of 1GB/s with an average processing rate of 250MB/s.
Backup proxy : on-host -> else you'll pump your network down !!!
Backup mode incremental so at end of backup it merges the files to purge out those outside retention date.

I currently only need to backup 5,5TB and it takes already 9 hours (3 hours merging on my EVA4400 repository with 36 FC disk @ 15k rpm)

So if you're planning to have more than 8TB data on a Nutanix you have to go for VmWare and Veeam.
With Hyper-V you'll have to wait for Server 2016 hopefully or have another backup method ...like snapshotting on the backup with retentions.
Alternativly (sorry Veeam) you can check with CommVault, as they can read out snapshot and export them incrementally...not tested myself.

PS : Dont forget :

Volume snapshots : Allow processing of multiple VM's with a single volume snapshot
Repository : Concurrent task : 4 or more
I/O control : enable parallel processing

If you handle 4 VM's at the time and those VM's have mulitple vhd's(for example 2), you'll be reading out 8 vhd's at average 50MB/s.
Nutanix limits the throughput per VHD, something a salesperson won't mention and support will describe as a protection future. :-)

And completly offtopic and pure out of frustration : YES I have the satadom wearout (field advisory 38) ...It was discovered on my cluster :-)

I think this is a similar/same issue your seeing on the Nutanix.

We run a number of Hyper-V clusters (have done for years), with iSCSI based storage currently one of our bigger clusters is 16 nodes running around 500VM's. Weve just finished putting in Veeam, all working ok no issues until we paused one of our nodes for maintenance purposes and all of sudden have warnings on all the backup jobs showing that CBT is no longer being used, backup times have gone from minutes to hours for customer VM's.

Unpaused the node so its back in production, CBT is now being used again. Bit of a ball ache when you have 500 VM's to backup/backup copy/replicate etc

The work around we have found that works is to evict the node from the cluster, perform any required maintenance than add the node back into the cluster.

This may well have been sorted with Server 2016 but Server 2016 still has to many major bugs in hyper-v for us to use as a production Hyper Visor at the moment, also a huge amount of work to upgrade all our clusters to 2016.

Something we will have to live with for now by the looks of things.
