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
The Expert Guide to VMware Data Protection
Virtualization is a very general term for simulating a physical entity by using software. There are many different forms of virtualization that may be found in a data center including server, network and storage virtualization. When talking about server virtualization there are many unique terms and concepts that you may hear that are part of the technology that makes up server virtualization.
Virtualization is the most disruptive technology of the decade. Virtualization-enabled data protection and disaster recovery is especially disruptive because it allows IT to do things dramatically better at a fraction of the cost of what it would be in a physical data center.

How to avoid VM sprawl and improve resource utilization in VMware and Veeam backup infrastructures
You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge.

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.
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: The Biggest Little Data Protection Company You Probably Haven't Heard Of (Yet)
Vembu wants to do more to let people know that it exists—it wants its own name to be in the marketplace and attached to its products—especially after hearing from many customers who desire to know whom the products they rely on truly belong to. So, in the past year, Vembu established relationships with more VARs and reached out directly to select enterprise and midmarket segments. It added 400 channel partners, 180 VARs, and 300 customers in 2014 alone.

If it appears that this analyst is impressed with Vembu, he is. Vembu’s feature set surpasses what one might presume to come from a backup company that most folks (in North America at least) haven’t heard of.And although it would be easy to assume that some of Vembu’s capabilities are mere boasts, the hesitations wash away with the recognition that this is a vendor with ten years in the business, and that well over half its workforce are R&D engineers. Said another way, Vembu appears to have been quietly solving its customers’ backup challenges for more than a decade through technology, instead of marketing.

In fact, not only did Vembu not have a marketing team until 2015, but it also didn’t have a sales team to speak of. This is an incredibly engineering-focused company—one whose revenues and customers have accumulated through word of mouth. But now, Vembu is building out a solid U.S.-based sales and marketing engine focused on penetrating awareness among IT decision makers, especially decision makers in the SMB segment.

The product Vembu will push in 2015, BDR 2.0, could be a “game changer” for Vembu’s growth. BDR appears to have the potential to quite effectively address the varied requirements of small and midmarket businesses who run mixed physical and virtual IT environments and who also want to leverage the cloud.

If Vembu continues to invest as much into its North American marketing and channel outreach programs as it historically has invested into engineering its technology, then 2015 could be the year that a lot of SMBs discover the “secret” to solving a lot of their backup problems.

European and APJ businesses may know Vembu, but many U.S. IT organizations will be surprised by the solution set of this ten-year-old company that is launching its first concerted marketing push into North America.

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.

Growing at 35% per year, Vembu branches out from its backup/recovery roots
Cloud­based backup/recovery is a cutthroat business with shrinking margins, commoditization and a surfeit of contenders trying to get a piece of the pie. The company's decision to push its resellers away from rebranding and into carrying Vembu's name on their services will give it much ­needed name/brand recognition in a crowded arena.

Vembu has grown its revenue 35% annually over the past two years and is on track to meet that mark in 2014. Key product additions this year include a suite of CRM applications and the introduction of on­premises virtual appliances (with physical appliances to come in the near future). The latter move puts Vembu in more direct competition with relatively well ­known players in the hybrid cloud backup battle.

Vembu is celebrating its 10­ year anniversary by exceeding the 60,000 ­customer milestone, sold mainly through its 4,400 channel partners. That compares with 55,000 customers and 4,000 resellers in February 2014. The company has added 400 resellers so far this year, and has begun to emphasize VARs in addition to its traditional target market of MSPs. Notable service­provider partners include Verizon's Terremark subsidiary, mindSHIFT Technologies, HostPapa and Hitachi Data Systems. The profitable Vembu claims to have exceeded 35% revenue growth in each of the past two years, and is on track for similar gains this year.

The company expects to have 200 employees by the end of 2014 (up from 160 in February), and 300 by the end of 2015. Most of its employees are near its headquarters in Chennai, India (with 65% engaged in R&D), but Vembu has been steadily expanding internationally. It opened an office in London this year, and relocated its US headquarters to Addison, Texas, where it expects to grow its workforce from 15 employees this year to 50 next year Vembu's worldwide distribution of partners roughly equates to its worldwide revenue distribution: 70% North America, 20% Europe and 10% AsiaPacific – a distribution that has remained fairly steady over the past year. However, although about 30% of its revenue comes from outside North America today, Vembu hopes to increase that to 50% in 2015. Key target markets for 2015 include the EU­5 countries, Scandinavia, Brazil and China

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.

How to Plan for Disaster Recovery
Disaster recovery scenario planning begins with identifying potential business interruption events. If you understand what the risks are, you can formulate a strategy of how to deal with them and mitigate, or at least limit, business impact. Once the disaster recovery scenarios are identified, the planning phase commences. This involves determining the probability of each scenario occurring and documenting the recovery operations.

Although no prevention method is 100% fool proof, risk avoidance and taking proactive measures for preparedness are essential elements of the disaster recovery process. Still despite all the measures you take to avoid a disaster, you must assume that a disaster will happen. Having this mind-set will help shape your decisions when it comes to planning for IT disaster recovery.
2017 Strategic Roadmap for Storage
Gartner offers recommendations for IT leaders responsible for infrastructure modernization and agility. Emerging storage hardware and software enable IT leaders to lower acquisition costs per terabyte and improve manageability. In addition to focusing on agility, automation and cost reductions, IT leaders should address the cultural changes and skill set shortages caused by digital business projects.
Key Findings:

•    Vendor consolidation continues in the storage and hyperconverged integrated system market, causing reassessments of vendor relationships, cost impacts and potential solution switches.
•    New storage initiatives focus on the need for agility, automation and cost reduction, as evidenced by the high adoption of solid-state arrays and HCIS, along with increasing interest in software-defined storage and drastically simplified integrated backup appliances.
•    Cloud storage continues to be a polarizing practice, with business more optimistic and IT more cautious, resulting in clashes and conflicts between tactical decisions and strategic movements.
•    Digital business and other new business initiatives often require changes in the culture between business units and IT operations; this highlights the challenges of skill set shortages in such areas as the evaluation and management of IT service providers.
