Quick question about failback process during DR scenario
Will the limitation mentionned below fixed in future version or will never be fixed ??
"Due to changes in VMware vSphere 7.0 and later, the replica failback operation forces digest recalculation for both source and target VMs. That is why the Quick rollback option is ignored for ESXi hosts starting from version 7.0."
Because, in our scenario
we have 55 VMs on our DR site
Between our main site and our DR site, we have an internet access 400Mbps and around 40ms latency
When we failover our 55 VMs, we work on them for 1 or 2 days
and we come back to main site
The failback for 55 VMs take around 18 hours....
The digest calculation take from one to several hours per VM
Example FailBack Process for one VM
