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.

The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Zerto Offsite Backup in the Cloud

What is Offsite Backup?

Offsite Backup is a new paradigm in data protection that combines hypervisor-based replication with longer retention. This greatly simplifies data protection for IT organizations. The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Why Cloud Backup?

  • Offsite Backup combines replication and long retention in a new way
  • The repository can be located in public cloud storage, a private cloud, or as part of a hybrid cloud solution.
  • Copies are saved on a daily, weekly and monthly schedule.
  • The data volumes and configuration information are included to allow VM backups to be restored on any compatible platform, cloud or otherwise.
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.

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
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

True 15-Minute RTO for Mission-Critical VM Systems with Vembu VMBackup Replication
Vembu Backup & Disaster Recovery (BDR) provides IT with a Disaster Recovery Management (DRM) system capable of meeting even more aggressive RTO and RPO goals than the previous release. For highly active database-driven systems, Vembu VMBackup leverages VMtools and VMware Changed Block Tracking (CBT) to perform incremental backups in 15-minute intervals with minimal impact on query processing. As a result, IT can limit data loss to 15 minutes of processing on active mission critical VMs.

The only way to recover a VM with full functionality and full performance without performing an explicit restore operation is through VM replication. Maintaining a replica VM, however, requires frequent and potentially expensive update processes that involve both explicit backup and implicit restore operations. To enable the extensive use of replication by IT, VMBackup adds critical optimizations to both restore and replication operations that dramatically minimize overhead on ESXi hosts and production VMs to just VM snapshot processing. Specifically, a BDR Backup server running on a VM is able to leverage hot-add SCSI transfer mode to write logical disk and logical disk snapshot files directly to a vSphere datastore, without involving the ESXi host for anything more than creating a VM snapshot.

A key a value proposition for Vembu VMBackup is its ability to directly read and write all backup and restore data directly to and from a datastore snapshot. As a result, Vembu VMBackup offloads all I/O overhead from production VMs and ESXi hosts, which is critical for maintaining an aggressive DRM strategy in a highly active virtual environment. What’s more, the performance of Vembu VMBackup in openBench lab's test environment made it possible to enhance support for a mission-critical OLTP application running on a VM using a combination of incremental backups for backup and replication. As a result, they were able to comply with a 30-minute RPO, restore the VM to a production environment in 5 minutes, and return to full-production level processing of business transactions—850 cTPS—in under 15 minutes.

VMBackup adds a new replica management module that enables an IT administrator to fully manage an initial failover and later finalize failover or failback with consolidation. In addition, BDR backup server simplifies all management functions by eliminating the need to run a separate client module on a BDR backup server, which becomes its own client within the BDR reporting hierarchy.

The Technology Behind ServerCentral DRaaS
ServerCentral provides turn-key DRaaS for virtual environments.
While virtualization has been a game-changing technology, most organizations have yet to realize the benefits of this transition. The optimization of IT processes for these environments, including security, compliance, and business continuity/disaster recovery (BC/DR), continue to lag behind. To date, BC/DR has been the most difficult. There haven’t been any virtual-ready, easily adoptable remote replication solutions. Until now.

Copy Data Management for Oracle Databases
Copy Data Management is fast-becoming a must-have solution for any enterprise Oracle environment. ECX integrates storage array copy processes (snapshots, replication, clones) with Oracle databases, allowing customers to leverage their existing storage infrastructure to eliminate copy sprawl, while dramatically improving their capabilities to deliver fresh copies of key databases to those functions and business units that demand them.

Oracle databases are a fundamental component of many organization’s most critical business processes. As such, copies of Oracle data are needed for many IT functions, including local and remote recovery, development and test, reporting, compliance and so on. According to IDC, over 80% of organizations maintain more than ten copies of every Oracle database instance at any given time. Not only does this create a massive infrastructure cost penalty, but the ongoing demand for copies also consumes valuable IT staff time and effort.

For this reason, Copy Data Management (CDM) is fast-becoming a must-have solution for any enterprise Oracle environment. ECX integrates storage array copy processes (snapshots, replication, clones) with Oracle, allowing customers to leverage their existing storage infrastructure to eliminate copy sprawl, while dramatically improving their capabilities to deliver fresh copies of key databases to those functions and business units that demand them. Catalogic supports arrays from Pure Storage, IBM, NetApp and EMC Unity.
