    ESG Lab Reports

    The goal of ESG Lab reports is to educate IT professionals about data center technology products for companies of all types and sizes. ESG Lab reports are not meant to replace the evaluation process that should be conducted before making purchasing decisions, but rather to provide insight into these emerging technologies. Our objective is to go over some of the more valuable feature/functions of products, show how they can be used to solve real customer problems and identify any areas needing improvement. ESG Lab's expert third-party perspective is based on our own hands-on testing as well as on interviews with customers who use these products in production environments. This ESG Lab report was sponsored by EMC.

    Introduction This report documents hands-on testing and validation of an EMC data protection solution for virtual environments using Avamar Virtual Edition with a Data Domain system, with a focus on the ease of integration, efficiency, scalability, and backup/restore performance.

    Background

    According to ESG research, over the past five years, IT professionals have consistently identified improving data backup and recovery, managing data growth, and increasing the use of server virtualization among their top IT priorities. In ESGs 2015 IT Spending Intentions Survey, only information security initiatives were cited more often (see Figure 1).1 One challenge for organizations is that data growth has a big impact on data backup and recovery: Ever-expanding volumes of data lengthen backup windows and recovery times, often to the point of interfering with production activities, while also demanding increasing amounts of back-end storage.

    In addition, many organizations have a difficult time finding the best option for protecting their ever-growing VMware virtual machines (VMs). Each VM requires an individual backup job, which can be difficult at scale. Traditional backup solutions struggle with the shared resources of VMs, putting SLAs at risk. VM backups often include redundant OS, application, and file datathe enormous amounts of data often mean backups cannot be completed during backup windows without leaving some VMs unprotected, and managing all these backups can be an operational nightmare. Another challenge is that running separate physical and virtual backups results in more servers, storage, and software to buy and manage, driving up costs and complexity.

    EMC Data Domain and Avamar

    This EMC data protection solution combines the simple and efficient Avamar backup/recovery software with the performance, scale, and efficiency of a Data Domain system.

    Data Domain

    Data Domain systems are highly scalable, purpose-built protection storage appliances that provide high-speed deduplication for backup and archiving, and replication for disaster recovery. The family of models can scale up to 86.4 PB of logical capacity. Variable-length deduplication maximizes dedupe rates, reducing backup and archive storage requirements by 10 to 30 times on average, making Data Domain a cost-effective alternative to other backup appliances or tape. These systems provide a target for a wide variety of enterprise backup and archiving workloads, including VMs, databases, mainframes, IBM i systems, NAS, e-mail, big data, content management apps, and remote offices. Data Domain systems support both backup and archive data simultaneously, eliminating the need to buy and manage a separate storage platform for archiving, as well as enabling global deduplication across both backup and archive data. Secure multi-tenancy is built into the Data Domain Operating System (DD OS), enabling hybrid cloud-based data protection-as-a-service for enterprises or service providers. Simple installation and easy management ensure lower OpEx.

    Data Domain systems are built with the Data Domain Data Invulnerability Architecture for maximum reliability and data integrity, performing inline verification of writes and reads and automatically recovering from I/O errors during ingest and retrieval. This ensures that backups and recoveries are successfully completed. Data Domain provides a wide range of backup options through support for NFS, CIFS, VTL, NDMP, and Data Domain Boost; the latter integrates with backup and enterprise applications to dramatically speed backups and reduce network utilization.

    Avamar

    Avamar backup software delivers daily full backups with variable length deduplication for VMware environments as well as for business-critical applications, NAS, desktops/laptops, and remote offices. Avamar can be deployed with a physical appliance for metadata or using the Avamar Virtual Edition appliance, as was used in this testing. When Avamar is combined with Data Domain, DD Boost code included in the Avamar client is used to distribute parts of the deduplication processing to the client side, reducing backup data and requiring less bandwidth. Avamars web-based management provides central control across a global deployment; it can also be managed through vSphere.

    For VMware environments, both guest- and image-level backups are supported. Avamar is integrated with VMwares vStorage APIs for Data Protection (VADP), enabling agentless guest backups. For image-level backups, Avamar offloads the backup process from t
