5 Fundamentals of Modern Data Protection
Some data protection software vendors will say that they are “agentless” because they can do an agentless backup. However, many of these vendors require agents for file-level restore, proper application backup, or to restore application data. My advice is to make sure that your data protection tool is able to address all backup and recovery scenarios without the need for an agent.
Legacy backup is costly, inefficient, and can force IT administrators to make risky compromises that impact critical business applications, data and resources. Read this NEW white paper to learn how Modern Data Protection capitalizes on the inherent benefits of virtualization to:
  • Increase your ability to meet RPOs and RTOs
  • Eliminate the need for complex and inefficient agents
  • Reduce operating costs and optimize resources
Application Response Time for Virtual Operations
For applications running in virtualized, distributed and shared environments it will no longer work to infer the performance of an application by looking at various resource utilization statistics. Rather it is essential to define application performance by measuring response and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

Massive changes are occurring to how applications are built and how they are deployed and run. The benefits of these changes are dramatically increased responsiveness to the business (business agility), increased operational flexibility, and reduced operating costs.

The environments onto which these applications are deployed are also undergoing a fundamental change. Virtualized environments offer increased operational agility which translates into a more responsive IT Operations organization. Cloud Computing offers applications owners a complete out-sourced alternative to internal data center execution environments. IT organizations are in turn responding to public cloud with IT as a Service (IaaS) initiatives.

For applications running in virtualized, distributed and shared environments, it will no longer work to infer the “performance” of an application by looking at various resource utilization statistics. Rather it will become essential to define application performance as response time – and to directly measure the response time and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

FlexApp Application Layering in ProfileUnity enables applications to be virtualized in such an innate way that they look native to the Windows OS and other applications.
FlexApp Application Layering in ProfileUnity enables applications to be virtualized in such an innate way that they look native to the Windows OS and other applications.

Application Layering leads to much higher rates of compatibility than previous technologies which used Application Isolation to virtualize applications. Once applications have been packaged for layering, they are containerized on virtual hard disks (VHDs) or VMDKs.  They can be centrally assigned to users on a machine-level or “context-aware” basis.

This whitepaper provides an overview of FlexApp concepts and ways in which FlexApp can serve as a cornerstone in an application delivery strategy.

Optimizing the way applications are delivered and managed has been an ongoing challenge in enterprise IT, and the variety of approaches over the years have been received with varying degrees of success. While every method has pros and cons, some of the most stubborn issues include time-to-deliver, application conflicts, plug-ins and licensing. The too-frequent result is high IT overhead, too many gold images and excess spending on application licenses.

Too many companies are settling on less than optimal solutions because that is all they are presented with and they are unaware of the true state of the art for application management. It is possible to dramatically reduce the number of Windows gold images, in some cases to a single image. It is possible to deliver exactly what each and every end user needs to do their job, and nothing else. It is possible for a user to log into a random system and instantly be presented with their personal desktop, all the right applications, plugins and add-ons, the right printers, and the right fonts. It is possible and it is simple.

Citrix AppDisk, when integrated with FSLogix Apps, provides a unique set of features that can improve end-user productivity, reduce IT overhead and lower the cost of desktop management. With FSLogix patent pending Image Masking technology, AppDisk gains very granular and powerful user-based policy control over every aspect of a user’s desktop and applications, and enhances the ability to distribute applications on network attached disk images. FSLogix Apps also enable AppDisks to scale to a much greater degree than any other similar technologies available today.

This document details what is possible when FSLogix is combined with Citrix AppDisk and suggests best practices for installing and configuring the products for maximum flexibility and applicability in various environments.
A New Approach to Per User Application Management
Our premise is simple: existing methodologies for delivering and deploying Windows applications are based upon outmoded ideas and outdated technology. There remains a need for a product that makes it simple for each user to have their Windows applications individually tailored for their device. When a user logs on they should see only the applications that they are licensed to use regardless of whether they are using cloud, virtual or traditional desktops.
Normal 0 false false false EN-US X-NONE X-NONE

A simple truth: Current application delivery and deployment solutions for Windows®-based desktops are often not fast enough, and the methods employed introduce complexities and limitations that cost enterprises valuable time, money and productivity. There is a strong need for a solution that is faster to deploy, simpler to use, and improves productivity rather than degrades it. In fact, the best solution would seamlessly and instantaneously personalizing the entire desktop, from profiles and printers to applications and extensions, while supporting license compliance and cost optimization. And, of course, it wouldn’t matter if the target desktops were physical, virtual, or cloud-based. FSLogix is delivering that solution today.

UNIQUE, CUTTING EDGE TECHNOLOGY

FSLogix has devised a revolutionary technique called Image Masking to create a single Unified Base Image that hides everything a logged in user shouldn’t see, providing predictable and real-time access to applications and profiles. This approach is driving unprecedented success in image reduction, with a side benefit of license cost optimization. Image masking functions identically across a wide range of Windows-based platforms, greatly simplifying the path from traditional to virtual environments, and dramatically reducing the management overhead required for enterprise desktops. This solution eliminates multiple layers of management infrastructure, creating a single, unified approach to image management, profile access, and application delivery.
Weighing Your Unified Monitoring Options: When Open Source Makes Sense

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.
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.

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.

Does Backup Need a File System of its Own?
VembuHIVETM is an efficient cloud file system designed for large-scale backup and disaster recovery (BDRTM) application with support for advanced use-cases. VembuHIVETM can be thought of as a File System of File Systems with in-built version control, deduplication (elimination of redundant information to enhance storage reduction), encryption, and in-built error correction.

Backup is just not about storage. It’s the intelligence on top of storage. Typically when businesses think of backup, they see it as a simple data copy from one location to another. Traditional file systems would suffice if the need were to just copy the data. But backup is the intelligence applied on top of storage where data can be put to actual use. Imagine the ability to use backup data for staging, testing, development and preproduction deployment. Traditional file systems are not designed to meet such complex requirements.

With the advent of information technology, more and more organizations are relying on IT for running their businesses. They cannot afford to have downtime on their critical applications and need instant access to data in the event of disaster. Hence, a new type of file system is necessary to satisfy this need. 

VembuHIVETM manages the metadata smartly through its patent-pending technology, in a way that is agnostic to the file system of the backup, which is why we call VembuHIVETM, a file system of file systems. This helps the backup application to instantly associate the data in VembuHIVETM to any file system metadata, thereby allowing on-demand file or image restores in many possible file formats. The data and metadata storage, harness cluster file system and computing and storage.

This is a really powerful concept that will address some very interesting use cases not just in the backup and recovery domain but also in other domains, such as big-data analytics.

The key to the design of VembuHIVETM is its novel mechanism to capture and generate appropriate metadata and store it intelligently in a cloud infrastructure. The increment data (the changes with respect to a previous version of the same backup) are treated like versions in a version control system (CVS, GIT). This revolutionary way of data capture and metadata generation provides seamless support to a wide range of complex restore use cases.
