CDP

[gingerdazza]

Hi.

Been loving the VeeamOn recorded sessions! Re: CDP, will CDP support surereplica DR testing in the future? Seems a big gap to me to have your tier 1 VIP VMs unable to be tested?

Also how scalable is CDP? (as in how many of your VMs can you CDP?)

Thanks

Hi Dazza,

Thank you for the feedback.

Yes, support for SureReplica is one of the features on our to-do list.

Speaking about scalability, it all depends on the hardware and network capabilities you can dedicate to CDP processing of VMs. Check this blog for details.

Thanks

2) You can check this whitepaper that contains some general recommendation (500-750 VMs or 1500 disks per backup server, 150 VMs or 500 disks per CDP policy).

Thanks!

The question about SureReplica for CDP is interesting because I'm not sure exactly how long we can accumulate I/O journal without flushing it into the disk file. So I assume at some point we'd have to pause CDP for the remaining duration of replica testing, but is this even acceptable for workloads with strict RPO requirements? Vladimir, did we think about this?

Sure, we have discussed this scenario and currently there are some thoughts on how we can apply retention to running CDP replica (test failover state) without pausing replication. The final solution is still in the works, but we are certainly aware of this issue. Thanks!

Is CDP not available on vCenters that do not have clustered hosts?
is this something that will be available in the future?

Hi Ahmed

This is a limitation from Vmware and not from Veeam.
I/O Filters can only be installed on top of a cluster and not on standalone esxi hosts. There is nothing Veeam can do about it.

https://docs.vmware.com/en/VMware-vSphe ... 3AA95.html

Installation is performed at an ESXi cluster lever. You cannot install the filters on selected hosts directly.
