VMware Data Replication Done Right
Until now the most common data replication technologies and methods essential to mission-critical BC/DR initiatives have been tied to the physical environment. Although they do work in the virtual environment, they aren’t optimized for it.

Until now the most common data replication technologies and methods essential to mission-critical BC/DR initiatives have been tied to the physical environment. Although they do work in the virtual environment, they aren’t optimized for it. With the introduction of hypervisor-based replication, Zerto elevates BC/DR up the infrastructure stack where it belongs: in the virtualization layer.

Challenges:

  • If a data replication solution isn’t virtual-ready, management overhead could be more than doubled.
  • Customer data is always growing, so a company can find its information inventory expanding exponentially and not have a data replication solution to keep pace.
  • Some replication methods remain firmly tied to a single vendor and hardware platform, limiting the organization’s ability to get the best solutions – and service – at the best price.

Benefits of Hypervisor-Based Replication:

  • Granularity - The ability to replicate at the correct level of any virtual entity is critical. Zerto’s solution can replicate all virtual machines and all of the meta data as well.
  • Scalability - Zerto’s hypervisor-based replication solution is software-based so it can be deployed and managed easily, no matter how fast the infrastructure expands.
  • Hardware-agnostic - Zerto’s data replication is hardware-agnostic, supporting all storage arrays, so organizations can replicate from anything to anything. This allows users to mix storage technologies such as SAN & NAS, and virtual disk types such as RDM & VMFS.
Introducing Cloud Disaster Recovery

Can mission-critical apps really be protected in the cloud?

Introducing: Cloud Disaster Recovery

Today, enterprises of all sizes are virtualizing their mission-critical applications, either within their own data center, or with an external cloud vendor. One key driver is to leverage the flexibility and agility virtualization offers to increase availability, business continuity and disaster recovery.

With the cloud becoming more of an option, enterprises of all sizes are looking for the cloud, be it public, hybrid or private, to become part of their BC/DR solution. However, these options do not always exist. Virtualization has created the opportunity, but there is still a significant technology gap. Mission-critical applications can be effectively virtualized and managed; however, the corresponding data cannot be effectively protected in a cloud environment.

Additional Challenges for Enterprises with the Cloud:

  • Multi-tenancy
  • Data protection & mobility
  • Lack of centralized management

Solutions with Zerto Virtual Replication:

  • Seamless integration with no environment change
  • Multi-site support
  • Hardware-agnostic replications
Application Protection & Recovery for VMware
Protect Applications, Not Data. How-to Guide: Application Protection and Recovery for VMware

Protect Applications, Not Data

How-to Guide: Application Protection and Recovery for VMware

When organizations are considering a business continuity/disaster recovery (BC/DR) solution, they need to look for a solution that not only protects and recovers the data, but also protects and recovers the application. Virtualized applications typically span multiple VMs and are more complex in terms of dependencies and infrastructure. They require recovery with write-order fidelity, something most replications solutions do not supply

Zerto Application Protection Features:

  • VM-level consistency grouping
  • Crash-consistent application recovery
  • Recovery of specific application objects
Backup is Not Replication - Backup VMware
Why Rely on Backup Shipping as Your VMware DR Solution? Some people think, if you want to protect data in your virtual VMware environment, your easiest solution is to backup VMware using snapshots or agents.

Why Rely on Backup Shipping as Your VMware DR Solution?

Some people think, if you want to protect data in your virtual VMware environment, your easiest solution is to backup VMware using snapshots or agents.  However, solutions like this, such as Veeam, can slow down your production environment, and they are difficult to scale.

However, many of us understand that backup is not disaster recovery. The right approach to a BC/DR solution is hypervisor-based replication.

With hypervisor-based replication you receive:

  • Continuous data replication
  • Recovery capabilities built specifically for VMware datacenters
  • Full consistency between and among all application components

Vembu Changes the Dynamics of Data Protection for  Business Applications in a vSphere Environment
This paper examines how to use Vembu BDR to implement distributed backup and disaster recovery (DR) operations in a centrally managed data protection environment with an ingenious twist. Rather than store image backups of VMs and block-level backups of physical and VM guest host systems as a collection of backup files, Vembu BDR utilizes a document-oriented database as a backup repository, dubbed VembuHIVE, which Vembu virtualizes as a file system.
Normal 0 false false false EN-US X-NONE X-NONE In this analysis, openBench Labs assesses the performance and functionality of the Vembu Backup & Disaster Recovery (BDR) host-level (a.k.a. agentless) data protection solution in a VMware vSphere 5.5 HA Cluster. For this test they utilized a vSphere VM configured with three logical disks located on separate datastores to support an Exchange server with two mailbox databases. Each of the mailbox databases was configured to support 1,000 user accounts.

This paper provides technically savvy IT decision makers with the detailed performance and resource configuration information needed to analyze the trade-offs involved in setting up an optimal data protection and business continuity plan to support a service level agreement (SLA) with line of business (LoB) executives.

To test backup performance, they created 2,000 AD users and utilized LoadGen to generate email traffic. Each user received 120 messages and sent 20 messages over an 8-hour workday. Using this load level, we established performance baselines for a data protection using direct SAN-based agentless VM backups.

In this scenario they were able to :

  • Finish crash-consistent incremental agent-less backups in 18 minutes, while processing our base transaction load of 12 Outlook TPS.
  • Restore a fully functional VM in less than 5 minutes as a Hyper-V VM capable of sustaining an indefinite load of 4 Outlook TPS
  • Recover all user mailboxes as .pst files from a host-level agentless VM backup with no need to schedule a Windows Client backup initiated within the VM’s guest Windows OS.
In a DR scenario, Vembu leverages the ability to restore a VM in any format, to provide an Instant-boot function, When Vembu Backup Server is installed on a server that is concurrently running Hyper-V, Vembu exports the datastores associated with a VM backup as Hyper-V disks and configures a VM to boot from the datastores.
Vembu OffsiteDR Server: Optimize RPO & RTO While Enhancing DR Resilience
Vembu BDR’s data protection solution enhances DRM operations by eliminating all potential single points of failure for restore functions. Using Vembu BDR Suite, IT is able to replicate backup data from multiple BDR Backup servers to a system running OffsiteDR Server within their own data center. As a result, IT garners an alternate system from which to recover protected VMs and physical servers using the same procedures that IT administrators employ on a BDR Backup server.

The ability to configure and deploy high-performance VMs within a vSphere virtual environment continues to put CIO’s under increasing pressure to deal with the rampant bête noire of IT: business continuity. What started with Line of Business (LoB) driven Service Level Agreements (SLAs) requiring IT to meet rigorous Recovery Time and Recovery Point Objectives (RTO and RPO) has grown into an auditable ISO standard (ISO22301) and an emerging software niche for Disaster Recovery Management (DRM) systems.

For this analysis, openBench Labs assessed the performance and functionality of the Vembu OffsiteDR Server, a DRM device that increases the resilience of recovery processes. Their initial intent was to examine the ability to restore data in the event of a catastrophic failure in vSphere environment, including:

  • A VM running BDR Backup server,
  • an ESXi host, and
  • a SAN device.

The full capabilities of Vembu OffsiteDR Server, however, quickly revealed that the device had a much broader operational impact. With the installation of OffsiteDR Server on an external physical server, they were free to configure end-to-end backup and restore operations in a way that optimized RTO and RPO for all business-critical application scenarios running in vSphere test environment.

In openBench lab's test environment, the combination of Vembu OffsiteDR Server deployed on a physical server with a Vembu BDR Backup server deployed on a VM provided a value proposition that extended far beyond the enhancement of DRM recovery resilience. With OffsiteDR Server installed on a physical server, they were able to optimally leverage VM and physical server platforms to easily implement all of the data protection functionality provided by Vembu BDR Suite, leverage all of the performance optimizations available to VMs in a vSphere environment, and do so in the most cost-effective system configuration.

Disaster Recovery Guide: DR in Virtualized Environments
In this guide you will learn about BC/DR planning with Zerto's Disaster Recovery Solutions for Virtualized Environments.
In today’s always-on, information-driven organizations, business continuity depends completely on IT infrastructures that are up and running 24/7. The costs of downtime are huge and data loss can put a company out of business. Data loss is not only caused by natural disasters, power outages, hardware failure and user errors, but more and more by software problems and cyber security related disasters. Therefore thorough security and business continuity strategies are crucial for modern businesses, minimizing data loss and downtime. Especially now, as data centers become more and more software defined, these private, hybrid and public clouds become more vulnerable to these kinds of threats.
