Update 1 is a fairly significant update and contains over 300 enhancements and bug fixes with a lot of those enhancements aimed at improving the scalability of the Backup & Replication platform that VCSPs can take advantage of. The biggest and most anticipated (and by far requested) update is for the support of vSphere 6.5…as you can see below there are a number of specific enhancements in this build aimed at 6.5 features:
- Encrypted VMs Support
- VMFS6 Support
- Virtual Hardware Version 13 support
- NBD Compression
- New Guest Interaction API Support
- New VM Tag API Support
Of most importance to me is to point out the fact the clients can now replicate in Virtual Machines with VM Hardware Version 13 meaning that you should get your production replication clusters up to ESXi 6.5 as soon as possible to avoid clients getting errors such as the one below:
This does pose an interesting problem for VCSPs offering Cloud Connect Replication as it represents a situation whereby holding back on vSphere upgrades could mean that clients (who are more likely to have less roadblocks to upgrade) can’t replicate newer VMs created on 6.5 into the VCSPs Replication Cluster. The workaround is to make clients aware that only specific Hardware Versions are supported for replication however it might be expected that providers offering these services are not bound by these limitations. This becomes an architectural/business discussion around separating IaaS vCenter’s from Replication vCenter’s …but that is a topic for another day.
For the moment, regardless of your underlying vSphere versions it’s worth planning the upgrade to Veeam Backup & Replication 9.5 Update 1 as soon as possible as it contains a number of enhancements beyond the ones listed above and some minor fixes for Cloud Connect.
