    • Zerto replication to Azure VMDK size limit

      Hi, We have a customer with a reasonably large VM which has one vmdk disk that is 2,134,760,448 KB in size (ie just over 2TB). Is this size of vmdk supported as part of a VM replication to Azure? Is there a limit on source VMDK size when replicating from VMware Zerto to Azure Zerto […]

    • The needed of ZVM with a single vCenter server

      We have a unique environment in that we have a single vCenter server but two disparate locations. When we initially installed Zerto, we installed a ZVM in each location. However, I noticed the other day that one of the two VMs was powered down. Do we really need two ZVMs with a single vCenter server?

    • Size of single Disk

      Back when we first started with Zerto, there was a size restriction for single disks for replication. Does that still apply? What is the restriction?

Can I attache the disk to a VM, increase the size to match the source […]

    • question: Remote site to remote site replication

        I am being asked by mgmt to see if Zerto can replicate servers from a remote office to another remote office using the ZVM located in the Datacenter. My assumption is that it can not without having another ZVM deployed in one of the remote sites.

    • Many VPGs in Bitmap Sync

    • ZVM resilience/HA

      Once we are doing local protection, lets assume to other SAN, what are the options to make the ZVM resilience as well? In case the main SAN failure, the vcenter will continue to work since it has HA and will have secondary replica over the 2nd SAN. But what about the ZVM? I think that […]

    • Is it possible to keep checkpoints after failover

      Posting this on behalf of Marcin.W Did a mini-DR test yesterday and one of the VMs turned out to have a problem after the VPG was already committed and we had to recover it from backups. I probably already know the answer but is there a way to somehow keep the checkpoints after doing a […]
