Use cases & benefits of Veeam Replica vs Hyper-V Replica?

Can anyone recommend an article or other resource which compares and contrasts Veeam Replication vs the native Hyper-V replica functionality? I know the difference between the two has been asked here before, but I haven't found a good in-depth comparison of the two. I'm looking for something that explains the best use cases for each product, and the pros and cons of each. Also, something relatively current, as I assume that Hyper-V replica has probably seen some changes since Server 2012R2.

If you have any links to such a reference I'd appreciate you sharing.

Thanks!

Hello,
I don't have an article but some conversations in the past and the result was the following (I hope I did not forget anything, feel free to add things):

Pro-Hyper-V:
- lower RPO times (30 seconds)

Pro-Veeam
- file / application restores from replica snapshots
- more flexible scheduling options (30 seconds, 5 minutes, or 15 minutes are the only options in Hyper-V)
- easier failback (failover seems also easy in Hyper-V)
- performance of VM not permanently reduced due to background replication (only snapshot performance impact during snapshot replication)
- one UI / Reporting for backup and disaster recovery

So if you need to go to replications every 30 seconds, then Hyper-V replication is the way to go. For most other use cases, Veeam is the more comfortable / flexible way.

Best regards,
Hannes

By far the biggest issue with Hyper-V replica is that it doubles storage I/O for each protected VM, when storage I/O is usually the most constrained resources in virtualization anyway. So, it's not really usable on a large scale.

Another option could be to use Storage Replica on your Hyper-V hosts to replicate the entire CSV to your DR site, which allows real-time synchronous or asynchronous replication, if you need an even lower RPO than 30 seconds.

Thank you all for the responses. I'm amazed that there hasn't been an article or whitepaper thoroughly contrasting the two products.

Hannes - I appreciate the detailed list.

Gostev - Doubling I/O on the primary hyper-v environment would definitely be a concern. I had read about that in an old post, but I thought it may have changed in the 5-6 years since.

Nmdange - While that might be a viable option for some, I don't think it's a good fit in our scenario.

If anyone has other input to share on the benefits of each product, please continue posting, I'd love to read it. I've got to present a recommendation to the boss soon, and any additional info I can use to make a decision and back it up would be very helpful.
