Field Technical Notice: FTN–20191104
Zerto Versions Affected:
- 7.5, 8.0
Microsoft recently announced the release of the Incremental Snapshots feature which Zerto leverages for supporting Azure Managed Disks (Premium SSD, Standard SSD and Standard HDD) as a part of the 7.5 and 8.0 Azure Platform Update.
The 7.5 and 8.0 Azure Platform Update capabilities with Azure Managed Disks on Incremental Snapshots are currently Generally Available (GA) for Zerto and Microsoft customers on Azure’s:
Americas: West Central US, West US, West US 2, East US, East US 2, South Central US, North Central US, Central US, Canada Central, Canada East, Mexico Central, and Brazil South regions
Azure Government: US Gov Arizona, US Gov Iowa, US Gov Texas, and US Gov Virginia regions
Europe: North Europe, West Europe, France Central, France South, UK South, UK West, Germany West Central, Germany North, Switzerland North, Switzerland West, Norway West, Norway East, and Spain Central regions.
Asia-Pacific: East Asia, Southeast Asia, Australia Central, Australia Central 2, Australia East, Australia Southeast, Central India, South India, West India, Japan East, Japan West, Korea Central, Korea South, China East, China North, China East 2, and China North 2 regions
Middle East and Africa: South Africa North, South Africa West, UAE Central, UAE North, Israel Central, and Qatar Central regions
In order to learn more about the GA of the new Azure Managed Disks Incremental Snapshot, customers are advised to refer to Microsoft’s blog.
The Zerto 7.5 and 8.0 software will install on any Azure region, but it will error out where Azure’s Incremental Snapshots functionality is not on a currently supported GA region.
The 7.5 and 8.0 Azure Platform Update does not support Unmanaged Disks. Customers operating on the 7.0 environment with VMs being replicated from Azure Unmanaged Disk into on-prem will be prevented from upgrading to 7.5 and consequently into 8.0
Zerto customers who desire both failover and failback capability into Azure Managed Disks were previously not able to failback without a downtime caused by moving data from Managed Disks into Unmanaged Disks.
Utilizing the new Azure Managed Disks feature in the latest Zerto 7.5, and 8.0 upgrade, customers will be able to leverage Microsoft’s Incremental Snapshot feature during a failback process. This feature is currently GA in Azure and customers using Zerto 7.5 and 8.0 will no longer need to convert Managed Disks to Unmanaged during the failback process.
This FTN describes Microsoft’s actions and the Azure regions where the Incremental Snapshot feature is GA.
Actions to take
Customers who would like to take advantage of Azure Managed Disks running on Microsoft GA regions are advised to make sure they have established network connection with the above supported regions, refer to Microsoft blog for the latest information and then contact their Zerto account reps to come onboard. Account representatives, please contact Jill.Lewis@zerto.com to finalize the onboarding to the code bits.
