10 benefits of network-based backup for the modern enterprise
To meet the demands of the global marketplace, Indian enterprises must support employees and customers that are distributed throughout the world. When people and their businesscritical data reside in multiple physical locations, the challenge of backing up and securing important business data becomes very significant. Traditional approaches involve deploying tape backup equipment and processes to each remote office location, and hiring or contracting local IT staff to manage the equipment and processes. Implementing this can be so expensive, complex and error-prone that for some enterprises it’s a completely unrealistic option.
An effective disaster recovery (DR) strategy requires that the company’s key data be stored redundantly at multiple physical locations. Such a system requires a data replication solution capable of transporting large amounts of data over the long distances required for geographical diversity between data storage sites. Data protection is simple: take everything and copy it somewhere far enough away so that you’ll have it when you need it — in an emergency. The challenge is how to do this in the most efficient, reliable and costeffective way.
Backing up remote site data to a central DR site across the WAN can simplify and greatly reduce the cost of data backup and recovery. Unfortunately, however, the performance of data backup across the WAN is dramatically impacted by WAN bandwidth limitations and network latency. Increasing costly WAN bandwidth may help increase performance to some extent, but cannot address the performance problems caused by network latency. This performance problem can make WAN-based backup unusable for many organizations.
Luckily, technology exists to overcome the performance problems associ- ated with moving vast quantities of data across long distances. WAN optimization, combined with related storage delivery technologies, are uniquely able to address this problem cost-effectively. Optimizing large-scale data backups within distributed enterprises, an optimized WAN-based backup solution can offer centralized backup and recovery of servers and desktop machines in remote offices, replication of centralized data repositories between data centers and backup of files and data to cloud services. Here are the top ten benefits enterprises can gain from deploying an optimized WAN-based disaster recovery solution. 10. Eliminate Backup in Branches: By effectively leveraging the wide area network ( WAN) for backup or replication of data in branch offices, you can save on the hardware, software, and administrative costs of local backup, tape duplication, and manual offsite transportation of tapes. 9. Reduce Costs: Data streamlining deduplicates WAN traffic, reducing disaster recovery bandwidth requirements by up to 95 percent, cutting your network costs significantly. Also, the elimination of branch backup brings massive savings for every office. 8. Reduce Administrative Overhead: Using the WAN as your data transport mechanism instead of physically transporting tapes provides automated, reliable DR operations. No more time wasted in the shuffling of tapes by IT staff (or non-IT staff for that matter!). 7. Reduce Security Risk: Eliminating tape transport and encrypting WAN traffic, coupled with centralized storage and role-based administration, makes passing industry and government regulatory audits much easier. 6. Protect More Data: By accelerating replication and backup up to 45x faster across the WAN, you can now cover not just mission-critical data, but all the data across your enterprise, while easily making your backup windows. This includes mobile worker laptop data too. 5. Protect More Often: Faster DR on the WAN also translates into great improvements in your recovery point objective (RPO), reducing the amount of time and data that could have been lost since your last backup. 4. Recover Faster: Restore data across the WAN instantly instead of waiting for backup tapes to be found and delivered for an improved recovery time objective (RTO). Or better yet, have all your data staged and ready to go in your remote DR site. 3. Centralize Storage or Move it to the Cloud: Whether you choose public or private cloud storage, enjoy the resilience and economies of scale for reduced costs and fast access from anywhere. 2. Make the Most of Your Storage Investment: Get more from your current storage hardware and software, and have the confidence of knowing that the solutions have been qualified and certified. 1. Have Your DR operations Play Nice with Your Business Apps: Use powerful quality of service (QoS) capabilities to match your priorities, whether you want replication to take precedence over other WAN traffic or vice versa, never slow things down.
