Now after a planned migration, vSphere Replication will automatically start tracking changes that occur to the recovered VMs and when a reprotect workflow is run, only those changes will be replicated to the new recovery site. With Site Recovery Manager and vSphere Replication 8.4, we’ve enhanced and optimized this process and built more intelligence into how it works.
And running the checksum process could take a while, especially in the case of larger (>1TB) virtual machines. This worked well for the most part, however, it was inefficient because it was usually run soon after the planned migration/failover, and very little of the virtual machine would have changed. It would run a checksum to compare the disk at the source site (what until the recent planned migration/failover had been the recovery site) to the target site (what until the recent planned/migration had been the protected site) and copy changes wherever they were found. In previous releases of vSphere Replication, when the “Reprotect” workflow was run after a planned migration or failover, vSphere Replication would treat this situation as if replication had just been configured for the first time and a seed file was used. Let’s take a look at all the cool new stuff that our engineers have cooked up for the SRM and vSphere Replication 8.4 release.

Site Recovery Manager 8.4 and vSphere Replication 8.4 have a full array of new features that will delight and satisfy both long-time and newer customers. If you’ve thought that you would be mistaken. Given all that they’ve already done, you might think that they’d start slowing down and maybe rest a little bit on their laurels. In the last few releases, the Site Recovery Manager and vSphere Replication engineering teams have resolved a number of long-standing customer requests including support for Virtual Volumes (8.3), support for vSphere Replication disk resizing (8.3), Site Recovery Manager as an appliance (8.2), vSphere Replication support for encrypting replication traffic and encrypted virtual machines (8.2) and compatibility with multiple versions of vCenter (8.1).
