Data Protection

Includes Backup/Recovery, Archiving, DPM, VTL, CDP, Data De-duplication, DRM.

Data is the lifeblood of an enterprise. And yet data has been protected in essentially the same fashion over the past two decades, i.e. by backing it up to tape and sending the tapes offsite. This method alone is no longer adequate and a spade of new technologies has become available in the last five years. These new technologies are already transforming the way data is protected, how long it is kept online, how it is archived. Recovery Management has emerged as a new discipline focused on recovering data rather than copying data. The new compliance requirements are essentially requiring companies of all sizes to upgrade their data protection infrastructures or be subject to huge fines. The level of innovation in this space is torrid. Taneja Group covers this space from end to end and has defined many of the new categories that now are considered the norm. The analysts that cover this space have deep industry backgrounds in developing and marketing these technologies.

Petabyte-Scale Backup Storage Without Compromise: A Look at Scality RING for Enterprise Backup

Traditional backup storage is being challenged by the immense growth of data. These solutions including tape, RAID devices that are gated by controllers and dedicated storage appliances simply aren’t designed for today’s enterprise backup storage at petabyte levels, especially when that data lives in geographically distributed environments. This insufficiency is due in large part to inefficiency and limited data protection, as well as the limited scalability and the lack of flexibility of these traditional storage solutions.

These constraints can lead to multiple processes and many storage systems to manage. Storage silos develop as a result, creating complexity, increasing operational costs and adding risk. It is not unusual for companies to have 10-20 different storage systems to achieve petabyte storage capacity, which is inefficient from a management point of view. And if companies want to move data from one storage system to another, the migration process can take a lot of time and place even more demand on data center resources.

And the concerns go beyond management complexity. Companies face higher capital costs due to relatively high priced proprietary storage hardware, and worse, limited fault tolerance, which can lead to data loss if a system incurs simultaneous disk failures. Slow access speeds also present a major challenge if IT teams need to restore large amounts of data from tape while maintaining production environments. As a result, midsized companies, large enterprises and service providers that experience these issues have begun to shift to software-defined storage solutions and scale-out object storage technology that addresses the shortcomings of traditional backup storage.

Software-defined scale out storage is attractive for large-scale data backup because these storage solutions offer linear performance and hardware independence – two core capabilities that drive tremendous scalability and enable cost-effective storage solutions. Add to this the high fault tolerance of object storage platforms, and it’s easy to see why software-defined object storage solutions are rapidly becoming the preferred backup storage approach for petabyte-scale data environments. A recent Taneja Group survey underscores the benefits of software-defined scale out storage. IT professionals indicated that the top benefits of software-defined, scale-out architecture on industry standard servers are a high level of flexibility (34%), low cost of deployment (34%), modular scalability (32%), and ability to purchase hardware separate from software (32%).

Going a step further, the Scality backup storage solution built upon the Scality RING platform offers the rare combination of scalability, durability and affordability plus the flexibility to handle mixed workloads at petabyte-scale. Scality backup storage achieves this by supporting multiple file and object protocols so companies can backup files, objects and VMs, leveraging a scale-out file system that delivers linear performance as system capacity increases, offering advanced data protection for extreme fault tolerance, enabling hardware independence for better price performance and providing auto balancing that enables migration-free hardware upgrades.

In this paper, we will look at the limitations of backup appliances and Network-Attached Storage (NAS) and the key requirements for backup storage at petabyte-scale. We will also study the Scality RING software-defined architecture and provide an overview of the Scality backup storage solution.

DP Designed for Flash - Better Together: HPE 3PAR StoreServ Storage and StoreOnce System

Flash technology has burst on the IT scene within the past few years with a vengeance. Initially seen simply as a replacement for HDDs, flash now is triggering IT and business to rethink a lot of practices that have been well established for decades. One of those is data protection. Do you protect data the same way when it is sitting on flash as you did when HDDs ruled the day? How do you take into account that at raw cost/capacity levels, flash is still more expensive than HDDs?  Do data deduplication and compression technologies change how you work with flash? Does the fact that flash technology is injected most often to alleviate severe application performance issues require you to rethink how you should protect, manage, and move this data?

These questions apply across the board when flash is injected into storage arrays but even more so when you consider all-flash arrays (AFAs), which are often associated with the most mission-critical applications an enterprise possesses. The expectations for application service levels and data protection recovery time objectives (RTOs) and recovery point objectives (RPOs) are vastly different in these environments. Given this, are existing data protection tools adequate? Or is there a better way to utilize these expensive assets and yet achieve far superior results? The short answer is yes to both.

In this Opinion piece we will focus on answering these questions broadly through the data protection lens. We will then look at a specific case of how data protection can be designed with flash in mind by considering the combination of flash-optimized HPE 3PAR StoreServ Storage, HPE StoreOnce System backup appliances, and HPE Recovery Management Central (RMC) software. These elements combine to produce an exceptional solution that meets the stringent application service requirements and data protection RTOs and RPOs that one finds in flash storage environments while keeping costs in check.

Transforming the Data Center: SimpliVity Delivers Hyperconverged Platform with Native DP

Hyperconvergence has come a long way in the past five years. Growth rates are astronomical and customers are replacing traditional three-layer configurations with hyperconverged solutions at record numbers. But not all hyperconverged solutions in the market are alike. As the market matures, this fact is coming to light. Of course, all hyperconverged solutions tightly integrate compute and storage (that is par for the course) but beyond that similarities end quickly.

One of the striking differences between SimpliVity’s hyperconverged infrastructure architecture and others is the tight integration of data protection functionality. The DNA for that is built in from the very start: SimpliVity hyperconverged infrastructure systems perform inline deduplication and compression of data at the time of data creation. Thereafter, data is kept in the “reduced” state throughout its lifecycle. This has serious positive implications on latency, performance, and bandwidth but equally importantly, it transforms data protection and other secondary uses of data. 

At Taneja Group, we have been very aware of this differentiating feature of SimpliVity’s solution. So when we were asked to interview five SimpliVity customers to determine if they were getting tangible benefits (or not), we jumped at the opportunity.

This Field Report is about their experiences. We must state at the beginning that we focused primarily on their data protection experiences in this report. Hyperconvergence is all about simplicity and cost reduction. But SimpliVity’s hyperconverged infrastructure also eliminated another big headache: data protection. These customers may not have bought SimpliVity for data protection purposes, but the fact that they were essentially able to get rid of all their other data protection products was a very pleasant surprise for them. That was a big plus for these customers. To be sure, data protection is not simply backup and restore but also includes a number of other functions such as replication, DR, WAN optimization, and more. 

For a broader understanding of SimpliVity’s product capabilities, other Taneja Group write-ups are available. This one focuses on data protection. Read on for these five customers’ experiences.

The HPE Solution to Backup Complexity and Scale: HPE Data Protector and StoreOnce

There are a lot of game-changing trends in IT today including mobility, cloud, and big data analytics. As a result, IT architectures, data centers, and data processing are all becoming more complex – increasingly dynamic, heterogeneous, and distributed. For all IT organizations, achieving great success today depends on staying in control of rapidly growing and faster flowing data.

While there are many ways for IT technology and solution providers to help clients depending on their maturity, size, industry, and key business applications, every IT organization has to wrestle with BURA (Backup, Recovery, and Archiving). Protecting and preserving the value of data is a key business requirement even as the types, amounts, and uses of that data evolve and grow.

For IT organizations, BURA is an ever-present, huge, and growing challenge. Unfortunately, implementing a thorough and competent BURA solution often requires piecing and patching together multiple vendor products and solutions. These never quite fully address the many disparate needs of most organizations nor manage to be very simple or cost-effective to operate. Here is where we see HPE as a key vendor today with all the right parts coming together to create a significant change in the BURA marketplace.

First, HPE is pulling together its top-notch products into a user-ready “solution” that marries both StoreOnce and Data Protector. For those working with either or both of those separately in the past in conjunction with other vendor’s products, it’s no surprise that they each compete favorably one-on-one with other products in the market, but together as an integrated joint solution they beat the best competitor offerings.

But HPE hasn’t just bundled products into solutions, it is undergoing a seismic shift in culture that revitalizes its total approach to market. From product to services to support, HPE people have taken to heart a “customer first” message to provide a truly solution-focused HPE experience. One support call, one ticket, one project manager, addressing the customer’s needs regardless of what internal HPE business unit components are in the “box”. And significantly, this approach elevates HPE from just being a supplier of best-of-breed products into an enterprise-level trusted solution provider addressing business problems head-on. HPE is perhaps the only company completely able to deliver a breadth of solutions spanning IT from top to bottom out of their own internal world-class product lines.

In this report, we’ll examine first why HPE StoreOnce and Data Protector products are truly game changing on their own rights. Then, we will look at why they get even “better together” as a complete BURA solution that can be more flexibly deployed to meet backup challenges than any other solution in the market today.

Full Database Protection Without the Full Backup Plan: Oracle’s Cloud-Scaled Zero Data Loss Recovery

Today’s tidal wave of big data isn’t just made up of loose unstructured documents – huge data growth is happening everywhere including in high-value structured datasets kept in databases like Oracle Database 12c. This data is any company’s most valuable core data that powers most key business applications – and it’s growing fast! According to Oracle, in 5 years (by 2020) most enterprises expect 50x data growth. As their scope and coverage grow, these key databases inherently become even more critical to our businesses. At the same time, the sheer number of database-driven applications and users is also multiplying – and they increasingly need to be online, globally, 24 x 7. Which all leads to the big burning question: How can we possibly protect all this critical data, data we depend on more and more even as it grows, all the time?

We just can’t keep taking more time out of the 24-hour day for longer and larger database backups. The traditional batch window backup approach is already often beyond practical limits and its problems are only getting worse with data growth – missed backup windows, increased performance degradation, unavailability, fragility, risk and cost. It’s now time for a new data protection approach that can do away with the idea of batch window backups, yet still provide immediate backup copies to recover from failures, corruption, and other disasters.

Oracle has stepped up in a big way, and marshaling expertise and technologies from across their engineered systems portfolio, has developed a new Zero Data Loss Recovery Appliance. Note the very intentional name that is focused on total recoverability – the Recovery Appliance is definitely not just another backup target. This new appliance eliminates the pains and risks of the full database backup window approach completely through a highly engineered continuous data protection solution for Oracle databases. It is now possible to immediately recover any database to any point in time desired, as the Recovery Appliance provides “virtual” full backups on demand and can scale to protect thousands of databases and petabytes of capacity. In fact, it offloads backup processes from production database servers which can increase performance in Oracle environments typically by  25%. Adopting this new backup and recovery solution will actually give CPU cycles back to the business.

In this report, we’ll briefly review why conventional data protection approaches based on the backup window are fast becoming obsolete. Then we’ll look into how Oracle has designed the new Recovery Appliance to provide a unique approach to ensuring data protection in real-time, at scale, for thousands of databases and PBs of data. We’ll see how zero data loss, incremental forever backups, continuous validation, and other innovations have completely changed the game of database data protection. For the first time there is now a real and practical way to fully protect a global corporation’s databases—on-premise and in the cloud—even in the face of today’s tremendous big data growth.

Array Efficient, VM-Centric Data Protection: HPE Data Protector and 3PAR StoreServ

One of the biggest storage trends we are seeing in our current research here at Taneja Group is that of storage buyers (and operators) looking for more functionality – and at the same time increased simplicity – from their storage infrastructure. For this and many other reasons, including TCO (both CAPEX and OPEX) and improved service delivery, functional “convergence” is currently a big IT theme. In storage we see IT folks wanting to eliminate excessive layers in their complex stacks of hardware and software that were historically needed to accomplish common tasks. Perhaps the biggest, most critical, and unfortunately onerous and unnecessarily complex task that enterprise storage folks have had to face is that of backup and recovery. As a key trusted vendor of both data protection and storage solutions, we note that HPE continues to invest in producing better solutions in this space.

HPE has diligently been working towards integrating data protection functionality natively within their enterprise storage solutions starting with the highly capable tier-1 3PAR StoreServ arrays. This isn’t to say that the storage array now turns into a single autonomous unit, becoming a chokepoint or critical point of failure, but rather that it becomes capable of directly providing key data services to downstream storage clients while being directed and optimized by intelligent management (which often has a system-wide or larger perspective). This approach removes excess layers of 3rd party products and the inefficient indirect data flows traditionally needed to provide, assure, and then accelerate comprehensive data protection schemes. Ultimately this evolution creates a type of “software-defined data protection” in which the controlling backup and recovery software, in this case HPE’s industry-leading Data Protector, directly manages application-centric array-efficient snapshots.

In this report we examine this disruptively simple approach and how HPE extends it to the virtual environment – converging backup capabilities between Data Protector and 3PAR StoreServ to provide hardware assisted agentless backup and recovery for virtual machines. With HPE’s approach, offloading VM-centric snapshots to the array while continuing to rely on the hypervisor to coordinate the physical resources of virtual machines, virtualized organizations gain on many fronts including greater backup efficiency, reduced OPEX, greater data protection coverage, immediate and fine-grained recovery, and ultimately a more resilient enterprise. We’ll also look at why HPE is in a unique position to offer this kind of “converging” market leadership, with a complete end-to-end solution stack including innovative research and development, sales, support, and professional services.
