The Starting Point for Backup, Recovery, and Archiving


The average midsize enterprise ($25 to $500 million in revenue) has the same general data concerns as its larger counterparts, but in a smaller environment with leaner budgetary and staffing resources. Many have implemented disparate devices, systems, and applications. And managing all of them requires significant manual effort, which can increase operational costs and compromise efficiency and data accuracy. Plus, operating in a 24x7, data-intensive environment affects backup windows and can increase restore times to unacceptable levels. What’s more, organizations must also comply with an ever-changing landscape of regulatory requirements and be ready to provide historical data at a moment’s notice. On top of all of these challenges, midsize organizations are typically growing at faster rates, creating unique data scalability issues.

Introduction If you are agonizing over how to meet your backup, recovery, and archiving needs…stop. Or, if you’re in the midst of planning how to meet your backup, recovery, and archiving needs, read on.

Backup, Recovery, and Archiving Challenges for Midsize Enterprises • With growth rates in excess of 25 percent in many cases, the data stores of midsize enterprises are fast approaching sizes once associated with only the largest enterprises. • To protect increasingly valuable data and prevent significant consequences, businesses must have mission-critical applications up and running within 24 hours. • Data that is worth having must be protected as it drives the business. • The single greatest data protection challenge is getting backup jobs done in allotted timeframes and performing faster recoveries. However, in today’s 24X7 operating environment, backup windows are smaller than ever and recovery times are increasing. • Nearly one out of four midsize enterprise users report that at least 20 percent of their tape-based backup operations fail due to media issues.

In the past, resource limitations have left midsize enterprises with very few affordable options for backup, recovery, and archiving. But today, there are a host of cost-effective, scalable hardware and software solutions available. These new offerings maximize existing technology investments, consolidate the management of multiple devices, and provide an unprecedented level of automation. Every environment is different and storage solutions are never “one size fits all,” so effective deployment requires careful consideration. A business must thoroughly assess its backup, recovery, and archiving environment, identify business goals, pinpoint pressing needs and weaknesses in its technology infrastructure, develop a solution based on appropriate technologies, and deploy it in a cost-effective, scalable way. Very often, this means engaging an experienced service or technology provider with extensive knowledge and resources. This EMC® Perspective paper serves as a guide for midsize enterprises that want to make backup, recovery, and archiving more effective and efficient. It highlights the key methods for assessing the backup environment, determining which technologies to deploy, and choosing the right technology and/or services partner with which to execute the strategy.

Phase One: Assessment The right backup, recovery, and archiving solution can help a business effectively manage increasing amounts of information, while ensuring its accessibility and availability to a rapidly growing user community. But in order to choose a solution that best meets its needs, a business must first understand its current environment. An independent assessment of the backup, recovery, and archiving environment by an experienced, knowledgeable technology and services partner is critical to developing this understanding. This assessment requires two basic steps: determining the points that are causing the most pain, and evaluating the current technology landscape for weaknesses in the infrastructure. The individual responsible for backup, recovery, and archiving deals with the associated processes and challenges on a daily basis and is the best resource for uncovering information on problem areas. A dialogue with this person will reveal not only the most pressing challenges of backup, recovery, and archiving, but also the elements of an ideal environment.

A good assessment should focus on business drivers and goals. It should also include questions about recent failed backups and restores and the applications that were involved, as well as the applications that most frequently need to be backed up and restored. The discussion should revolve around the applications and data that are most critical to the business and most frequently require access. Finally, it should uncover all recovery-time objectives (RTOs) and regulatory requirements for backing up data to an offsite location.

Armed with a sense of the most critical objectives related to backup, recovery, and archiving and the obstacles that stand in the way of those objectives, the technology and/or services partner should begin a comprehensive analysis of the backup and recovery environment along with the related archiving processes and infrastructure. Here, the partner and the business work together to gather information about policies and procedures, take inventory of the existing equipment (which can be accomplished with data collection software tools), and audit the data residing on file systems for space by file type, file owner, and last-access date.

Phase Two: Solution Design At this stage, the environmental and technological assessments have uncovered the most pressing challenges associated with backup, recovery, and archiving and the infrastructural weaknesses that are creating these challenges. Now, it is necessary to evaluate potential solution deployment options based on this information and choose those that best fit the needs and objectives of the business. This will include examining the components and benefits of each option, as well as the technology available for midsize enterprises.

About Recovery Objectives • Recovery-time objective (RTO) is the time required to recover data after downtime. • Recovery-point objective (RPO) is the maximum time window of data loss the business can afford for the application. • The population aiming at RTO and RPO of less than 20 minutes has doubled since 2004.

Active Archiving. If the assessments from the previous phase uncovered excessive amounts of static data, active archiving can help reduce the cost of storing this information, while ensuring accessibility. Active archiving includes techniques such as single-instancing, which stores only a single copy of a file in a pool of storage. This approach minimizes the number of files that will be routinely backed up in the production environment. Another approach involves simply moving inactive information onto less-expensive storage platforms. But manually going through a company’s files to identify documents that are no longer actively used is simply too big a job to be practical. The best approach is to use software automation tools to identify static data and move it onto Tier 2 or Tier 3 storage platforms. Here, the data remains easily accessible by corporate users, yet it resides on a less-expensive storage platform. Cost isn’t the only benefit. Ongoing active archiving can also keep production applications streamlined and operating at peak performance, improve information access, and ensure regulatory compliance.1 Every business has recovery-point objectives (RPOs) and RTOs upon which the recovery process should be based. Active archiving technology supports these objectives with a variety of features, including tiered service levels, automated movement of information to more cost-effective storage media, and simplified assessment, implementation, and management of the backup, recovery, and archiving environment. Plus, all of these features fully integrate with the business’s existing databases, file systems, and e-mail applications for seamless data exchange. Disk-based backup. If the assessment uncovered excessive instances of tape media failures in a business’s recent history, storing data on disks rather than tape can make backups more reliable, as well as faster and less labor-intensive. Disk technology has a significantly lower TCO than tape technology and enables backups to take place continuously or at least within a more reasonable time frame, so more data can be kept online for faster recoveries.2 Recent advances in advanced technology attachment (ATA) disks and the availability of low-cost Fibre Channel drives (LCFCD) have made disk costs comparable to tape—with better performance and reliability. Plus, backup software applications can maximize the value of a disk solution by leveraging high-speed disk arrays to accelerate backup and recovery. A virtual tape library should be considered with disk backup technology. The benefits of a virtual tape library include recovery and backup at channel speeds many times faster than tape. In fact, a virtual tape library can deliver 30 to 60 percent faster backups and up to 90 percent faster recoveries than traditional tape-based offerings. Plus, with this technology, IT staff no longer needs to mount, position, and dismount tapes or worry about the reliability of the media.3 A virtual tape library integrates low-cost ATA drives, tape emulation software, and powerful functionality to deliver a simple-to-deploy and easy-to-use disk-based backup and restore solution that can even back up networked storage. This technology is available in a wide range of sizes and capacities to suit the needs of any size business and is highly scalable for growth.

Consolidation. If the assessment detected more than one backup application or multiple copies of the same backup application, consolidating them onto a single, scalable platform can result in more efficient use of storage space. Consolidation separates storage from individual servers and establishes a shared, centralized pool, usually connected by a network. By centralizing backup and recovery, consolidation offers a wide array of benefits to the business. These include improved data availability, management, and performance. Done properly, consolidation solutions should be scalable and flexible to address a wide range of challenges from the simplest to the most complex. A solution entails a wide range of options that includes IP storage consolidation, mid-range tiered storage and server consolidation, and high-end storage consolidation. Tape Library. If the environmental assessment uncovers a requirement for point-in-time data copies offsite for regulatory purposes, a tape library provides a cost-effective solution. A tape library is a collection of magnetic tape cartridges and tape drives that can be ejected out of the library and shipped to an offsite location. This technology can work in conjunction with disk-based backup systems to provide the full benefits of a tiered backup infrastructure. Weekly backups can stay on disk for 30 days, migrated to tape for six months, and finally, be shipped offsite for three or more years to better meet offsite regulatory requirements.
