2 Introduction The disk backup appliance market continues to grow with major server, storage, and backup software vendors investing research and development in maturing available features. These aren t just a bunch of disks; look closely at differentiating features to find the solution that best fits your needs. This Research Is Designed For: Enterprises seeking to select a solution for diskbased backup. Selection will differ according to the size of the company and its capacity requirements. Selection will also vary according to a requirement of virtual tape library (VTL). Enterprises looking to make the switch from tape to disk-based backup. This Research Will Help You: Understand what s new in the disk-based backup market. Evaluate backup and recovery vendors and products for your enterprise needs. Determine which products are most appropriate for particular use cases and scenarios. 2

3 Executive Summary Info-Tech evaluated ten competitors in the Disk Backup Appliance market, including the following notable performers: Champions: Symantec s NetBackup 5030 appliance offers flexible replication capabilities and easy deployment and integration within existing NetBackup environments. ExaGrid s GRID architecture simplifies scaling of capacity and performance for its customers at a cost effective price point. Quantum differentiates its DXi-Series appliances with a rich feature set, ease of scaling and management, and a continued commitment to innovation in data protection. HP has expanded its StoreOnce portfolio of backup appliances into the enterprise with the HP StoreOnce B6200. Its two-node clusters with autonomic restart capabilities bring high availability to backup. Value Award: Symantec, through independent licensing of hardware and software, makes adding the 5030 easy for existing customers. Trend Setter Award: Quantum innovated in the past with upstream dedupe and its DXiV1000 virtual appliance, and its new Dynamic Disk Pools technology improves on RAID6 architecture for faster drive rebuilds, which will be key to its support for 3TB drives. Info-Tech Insight 1. Scalability: Data deduplication used to be a differentiator in disk backup, but the ability to scale capacity and deduplicate that capacity is now a key differentiator in the market. Innovating vendors are finding ways to improve on the old scale up model with either scale out or software-enabled expansion. 2. Replicability: All reputable solutions offer both bidirectional and fan-in replication, but organizations with more complex needs will need a vendor with one-to-many, many-tomany, and/or cascaded replication capabilities. 3. Flexibility: As organizations require more aggressive RPOs and RTOs in combination with nondedupable workloads and archiving, many require a mix of disk and tape, and control over whether a job is deduplicated or not. Look to solutions that support both tape support and an option to turn deduplication off. 3

4 Market Overview How it got here Spinning disk simplified management and speeded restore. Many organizations moved to disk to eliminate tape rotation headaches and improve recovery times. Deduplication became mainstream. Originally championed by start-up innovators such as market leader Data Domain, dedupe has become mainstream, driving down the cost per terabyte differences between disk and tape. Deduplicating Virtual Tape Library (VTL) appliances had the added advantage of being a drop in solution. A VTL could be installed in place of a retired tape library with no change to backup procedures or software. Disk-to-disk backup became the dominant architecture. A 2012 Info-Tech survey found 62% investing in a new backup architecture were focused on disk-to-disk (vs. 17% disk-to-tape). Many organizations have now moved tape to an archiving role or have eliminated tape altogether. Where it s going Replication flexibility has become an area of differentiation. Most disk backup appliances can conduct bidirectional replication between sites and fan-in replication from Remote and Branch Offices (ROBOs), but some solutions can also replicate from one site to many or enable cascaded replication schemes. Appliance vendors are getting pressure to enable high availability. Virtual infrastructures have driven up business expectations for agility and availability, and these expectations are trickling down to backup. Look for vendors to add dual controller architectures to their portfolio if they haven t already. Big Data will make speed and scalability more important. Organizations of all sizes are seeing significant data growth, which has an even greater impact on backup storage than primary storage because multiple copies of data are often retained. Scaling of both capacity and throughput will become more and more important as these data volumes grow further. As the market evolves, capabilities that were once cutting edge become default and new functionality becomes differentiating. Deduplication as well as bidirectional and fan-in replication have become Table Stakes capabilities and should no longer be used to differentiate solutions. Instead, focus on scalability and flexibility in replication options to get the best fit for your requirements. 4

5 Disk Backup Vendor selection / knock-out criteria: market share, mind share, and platform coverage For the purposes of this Vendor Landscape report, vendors must be able to provide a deduplicating disk backup appliance and be capable of pricing out the disk appliance component separately from backup software. In addition, Info-Tech focused on those vendors that have a strong market presence and/or reputational presence among mid and large-sized enterprises. Included in this Vendor Landscape: EMC. Market share leader and early entrant in the space with its purchase of Data Domain in Dell. Entering the deduplicating disk backup appliance market, Dell has been adding functionality to its DR4000 series appliances quickly and continuously since initially going to market in ExaGrid. Focused solely on backup appliances, ExaGrid s unique GRID architecture for simple scaling of capacity and performance has made it an appealing solution, especially for small to mid-market customers. FalconStor. A mature data protection vendor, FalconStor offers flexible replication and deduplication options for midmarket and enterprise customers. Fujitsu Technology Solutions. Long time seller of reliable disk-based storage, Fujitsu offers both appliances for midmarket and gateway devices for enterprise. HP.

7 The Info-Tech Disk Backup Vendor Landscape The Zones of the Landscape Champions receive high scores for most evaluation criteria and offer excellent value. They have a strong market presence and are usually the trend setters for the industry. The Info-Tech Disk Backup Vendor Landscape: ExaGrid Market Pillars are established players with very strong vendor credentials, but with more average product scores. Innovators have demonstrated innovative product strengths that act as their competitive advantage in appealing to niche segments of the market. Emerging Players are newer vendors who are starting to gain a foothold in the marketplace. They balance product and vendor attributes, though score lower relative to market Champions.

9 The Info-Tech Disk-based Backup Appliance Value Index What is a Value Score? The Value Score indexes each vendor s product offering and business strength relative to their price point. It does not indicate vendor ranking. Champion On a relative basis, Symantec maintained the highest Info-Tech Value Score TM of the vendor group. Vendors were indexed against Symantec s performance to provide a complete, relative view of their product offerings. Vendors that score high offer more bang-forthe-buck (e.g. features, usability, stability, etc.) than the average vendor, while the inverse is true for those that score lower. Price-conscious enterprises may wish to give the Value Score more consideration than those who are more focused on specific vendor/product attributes Average Score: *The vendor declined to provide pricing and publically available pricing could not be found For an explanation of how Price is determined, see Information Presentation Price Evaluation in the Appendix.

10 Table Stakes represent the minimum standard; without these, a product doesn t even get reviewed Feature Bidirectional Replication Fan-in (N:1) Replication Deduplication Encryption In Flight Compression CIFS/NFS Support The Table Stakes What it is: Appliance A can be configured to replicate to appliance B, and vice versa. Multiple appliances can replicate over the WAN or LAN to one central appliance. Redundant data objects are eliminated within the backup appliance, either inline or post process. Data is encrypted before replicating over WAN using Secure Socket Layer (SSL) protocol. Encodes data on the appliance with fewer bits than which the data was originally encoded. Ability to leverage Common Internet File System and Network File System remote file access protocols. What Does This Mean? The products assessed in this Vendor Landscape TM meet, at the very least, the requirements outlined as Table Stakes. Many of the vendors go above and beyond the outlined Table Stakes, some even do so in multiple categories. This section aims to highlight the products capabilities in excess of the criteria listed here. If Table Stakes are all you need from your Disk Backup solution, the only true differentiator for the organization is price. Otherwise, dig deeper to find the best price to value for your needs. 10

11 Advanced Features are the capabilities that allow for granular market differentiation Scoring Methodology Info-Tech scored each vendor s features offering as a summation of their individual scores across the listed advanced features. Vendors were given 1 point for each feature the product inherently provided. Some categories were scored on a more granular scale with vendors receiving half points. Feature One-to-Many (1:N) Replication Many-to-Many (N:N) Replication Cascaded Replication Scale-out Architecture Upgradable Controller Bandwidth Throttling Tape Integration Encryption at Rest No Dedupe Option Multi-Controller Configuration Advanced Features What we looked for: Can be configured to replicate from one primary appliance to many appliances (at other sites). Replication topology among three or more sites each appliance has multiple site destinations. Can replicate from appliance A to appliance B, and then from appliance B to appliance C. Can add nodes to increase throughput and capacity, and appear as a single pool of storage. Controllers can be upgraded to increase throughput and/or performance. Appliance s bandwidth utilization can be controlled directly and scheduled. Appliance enables direct integration with tape systems without third-party software intervention. Data can be physically stored in an encrypted state on the appliance. Optionally stores data in undeduplicated state such as image files or pre-compressed data. Provides true high availability through redundant controller configuration for each appliance.

21 Vendor Landscape Methodology: Overview Info-Tech s Vendor Landscapes are research materials that review a particular IT market space, evaluating the strengths and abilities of both the products available in that space, as well as the vendors of those products. These materials are created by a team of dedicated analysts operating under the direction of a senior subject matter expert over a period of six weeks. Evaluations weigh selected vendors and their products (collectively solutions ) on the following eight criteria to determine overall standing: Features: The presence of advanced and market-differentiating capabilities. Usability: The intuitiveness, power, and integrated nature of administrative consoles and client software components. Affordability: The three-year total cost of ownership of the solution. Architecture: The degree of integration with the vendor s other tools, flexibility of deployment, and breadth of platform applicability. Viability: The stability of the company as measured by its history in the market, the size of its client base, and its financial performance. Strategy: The commitment to both the market-space, as well as to the various sized clients (small, mid-sized, and enterprise clients). Reach: The ability of the vendor to support its products on a global scale. Channel: The measure of the size of the vendor s channel partner program, as well as any channel strengthening strategies. Evaluated solutions are plotted on a standard two by two matrix: Champions: Both the product and the vendor receive scores that are above the average score for the evaluated group. Innovators: The product receives a score that is above the average score for the evaluated group, but the vendor receives a score that is below the average score for the evaluated group. Market Pillars: The product receives a score that is below the average score for the evaluated group, but the vendor receives a score that is above the average score for the evaluated group. Emerging Players: Both the product and the vendor receive scores that are below the average score for the evaluated group. Info-Tech s Vendor Landscapes are researched and produced according to a strictly adhered to process that includes the following steps: Vendor/product selection Information gathering Vendor/product scoring Information presentation Fact checking Publication This document outlines how each of these steps is conducted. 21

22 Vendor Landscape Methodology: Vendor/Product Selection & Information Gathering Info-Tech works closely with its client base to solicit guidance in terms of understanding the vendors with whom clients wish to work and the products that they wish evaluated; this demand pool forms the basis of the vendor selection process for Vendor Landscapes. Balancing this demand, Info-Tech also relies upon the deep subject matter expertise and market awareness of its Senior, Lead, and Principle Research Analysts to ensure that appropriate solutions are included in the evaluation. As an aspect of that expertise and awareness, Info-Tech s analysts may, at their discretion, determine the specific capabilities that are required of the products under evaluation, and include in the Vendor Landscape only those solutions that meet all specified requirements. Information on vendors and products is gathered in a number of ways via a number of channels. Initially, a request package is submitted to vendors to solicit information on a broad range of topics. The request package includes: A detailed survey. A pricing scenario (see Vendor Landscape Methodology: Price Evaluation and Pricing Scenario, below). A request for reference clients. A request for a briefing and, where applicable, guided product demonstration. These request packages are distributed approximately twelve weeks prior to the initiation of the actual research project to allow vendors ample time to consolidate the required information and schedule appropriate resources. During the course of the research project, briefings and demonstrations are scheduled (generally for one hour each session, though more time is scheduled as required) to allow the analyst team to discuss the information provided in the survey, validate vendor claims, and gain direct exposure to the evaluated products. Additionally, an end-user survey is circulated to Info-Tech s client base and vendor-supplied reference accounts are interviewed to solicit their feedback on their experiences with the evaluated solutions and with the vendors of those solutions. These materials are supplemented by a thorough review of all product briefs, technical manuals, and publicly available marketing materials about the product, as well as about the vendor itself. Refusal by a vendor to supply completed surveys or submit to participation in briefings and demonstrations does not eliminate a vendor from inclusion in the evaluation. Where analyst and client input has determined that a vendor belongs in a particular evaluation, it will be evaluated as best as possible based on publicly available materials only. As these materials are not as comprehensive as a survey, briefing, and demonstration, the possibility exists that the evaluation may not be as thorough or accurate. Since Info-Tech includes vendors regardless of vendor participation, it is always in the vendor s best interest to participate fully. All information is recorded and catalogued, as required, to facilitate scoring and for future reference. 22

23 Vendor Landscape Methodology: Scoring Once all information has been gathered and evaluated for all vendors and products, the analyst team moves to scoring. All scoring is performed at the same time so as to ensure as much consistency as possible. Each criterion is scored on a ten point scale, though the manner of scoring for criteria differs slightly: Features is scored via Cumulative Scoring Affordability is scored via Scalar Scoring All other criteria are scored via Base5 Scoring In Cumulative Scoring, a single point is assigned to each evaluated feature that is regarded as being fully present, partial points to each feature that is partially present, and zero points to features that are deemed to be absent or unsatisfactory. The assigned points are summed and normalized to a value out of ten. For example, if a particular Vendor Landscape evaluates eight specific features in the Feature Criteria, the summed score out of eight for each evaluated product would be multiplied by 1.25 to yield a value out of ten. In Scalar Scoring, a score of ten is assigned to the lowest cost solution, and a score of one is assigned to the highest cost solution. All other solutions are assigned a mathematically determined score based on their proximity to / distance from these two endpoints. For example, in an evaluation of three solutions, where the middle cost solution is closer to the low end of the pricing scale it will receive a higher score, and where it is closer to the high end of the pricing scale it will receive a lower score; depending on proximity to the high or low price it is entirely possible that it could receive either ten points (if it is very close to the lowest price) or one point (if it is very close to the highest price). Where pricing cannot be determined (vendor does not supply price and public sources do not exist), a score of 0 is automatically assigned. In Base5 scoring a number of sub-criteria are specified for each criterion (for example, Longevity, Market Presence, and Financials are subcriteria of the Viability criterion), and each one is scored on the following scale: 5 - The product/vendor is exemplary in this area (nothing could be done to improve the status). 4 - The product/vendor is good in this area (small changes could be made that would move things to the next level). 3 - The product/vendor is adequate in this area (small changes would make it good, more significant changes required to be exemplary). 2 - The product/vendor is poor in this area (this is a notable weakness and significant work is required). 1 - The product/vendor is terrible/fails in this area (this is a glaring oversight and a serious impediment to adoption). The assigned points are summed and normalized to a value out of ten as explained in Cumulative Scoring above. Scores out of ten, known as Raw scores, are transposed as-is into Info-Tech s Vendor Landscape Shortlist Tool, which automatically determines Vendor Landscape positioning (see Vendor Landscape Methodology: Information Presentation - Vendor Landscape, below), Criteria Score (see Vendor Landscape Methodology: Information Presentation - Criteria Score, below), and Value Index (see Vendor Landscape Methodology: Information Presentation - Value Index, below). 23
