Zerto Virtual Replication 4.5 is GA!

Zerto Virtual Replication 4.5 ArchitectureExciting news from our friends at Zerto today! The Zerto Virtual Replication 4.5 have been released. Let’s have a look at what’s new in this release.

Zerto Virtual Replication 4.5 includes the following new features

New Installation

The Zerto installation has been totally redesigned. As well as a new sharper look, the installation flows have been updated to make them easier to understand.You can perform a silent installation of Zerto Virtual Replication 4.5 in all environments. The silent installation has been changed so you can specify the installation configuration as part of the silent installation command.

Permissions – Role-based Access Control

Handling permissions has been extended to enable applying permissions to specific entities such as ZORGs, VPGs, and sites. Roles can be defined with a set of privileges that define an operation or a set of operations that can be performed, such as managing a VPG or VRA. These roles can then be assigned to users and groups of users.

Improved Recovery

  • Adding Virtual Machines to a VPG – After adding virtual machines to a VPG, the additional virtual machines are synchronized with the recovery site. During this synchronization, the original virtual machines in the VPG are still protected and canbe failed over. The protection status is Meeting SLA for n/m where n is the number of original virtual machines in the VPG and m is the total number of virtual machines in the VPG, including the added virtual machines.
  • More Robust Journal Health – The journal is automatically reconfigured and journal history increased beyond the configured history SLA, to ensure that the SLA defined for the VPG is maintained during long network outages and other incidents that prevent checkpoints being written to the journal.

vRA Enhancements 

  • vRA Deployment (vSphere Environments) – vRAs can be installed using vSphere Installation Bundle, VIB, so that a password to install the vRA on a host is no longer required. This makes automating the installation of vRAs in a vSphere environment using APIs simple.
  • Enhanced Handling of Ghost vRAs – A vRA could enter a ghost state for a few reasons. In Zerto Virtual Replication version 4.5 some of these situations resolve themselves automatically and some require user input.

Journal Feature Enhancements

  • Journal Compression – Data passed from the protected site to the recovery site is saved in the journal in a compressed format. The data is compressed when it is passed over the network to the recovery side and uncompressed when a recovery operation is required. This uses
    less space without impacting the RTO. Compression is enabled automatically when WAN compression is enabled for a VPG.
  • Journal Extended to 14 days – Journal history has increased from a maximum of 5 days to 14 days. Also the default journal has changed from 4 hours to 1 day.
  • Journal Default Sized Changed From Unlimited – When defining the journal size for a VPG, the default has been changed from unlimited to 150GB.

API Extensions

The following changes have been made to the APIs

  • Alerts – Enables retrieving information about alerts as well as being able to dismiss or undismiss an alert.
  • Events – Enhanced to include the ability to retrieve event information by category, entity or type.
  • Tasks – Enhanced to include the ability to retrieve information by task type.
  • Virtualizationsites – Enhanced to include the ability to retrieve information to use in the vpgsettings API.
  • VPGs – Enables deleting a VPG, retrieving event information by VPG priority, retention policy, status or substatus.
  • VpgSettings – You can manage VPGs using both the VPGs API or the VpgSettings API. Use the VPGs API to perform actions on a VPG, such as failing over a VPG, cloning a VPG or testing a VPG.

Cmdlet Enhancements

The export-settings cmdlet can be used to export the VPG settings between the site and a paired when one Zerto Virtual Manager is down, by running the cmdlet from the paired Zerto Virtual Manager.

vSphere and Hyper-V Support

  • Zerto Virtual Replication 4.5 supports vSphere version 6 and vCloud Director versions 5.6.3 and 5.6.4.
  • Zerto Virtual Replication supports Microsoft SCVMM and Hyper-V hosts 2012 R2 Rollups 1-9 but recommends using Rollups 5-9.

Additional vCD Functionality

  • Changing the Recovery Storage Profile – You can now change the recovery storage profile when recovering to vCD without incurring an initial sync.
  • Support for NAT Rules When Recovering to vCD – When both the protected and recovery sites are vCD environments, NAT rules on source vApp networks can be copied to the recovery vApp during recovery.

Encryption When Recovering to AWS

All replicated data from protected virtual machines to AWS can be encrypted in S3. For details, contact Zerto support.

Easier Editing in Tables

Values in tables, especially in the VPG wizard, can be edited inline by hovering the mouse over the value and then click the pencil icon to edit the value.
