Network Based Backup

SOLUTION BRIEF
Riverbed optimizes the transfer of data over the WAN for backup and datamigration purposes. Through its revolutionary technology, Network-Based Backup and Riverbed delivers the following capabilities: ®»»Enables centralized, disk-to-disk backup strategies that simplify remote office Data Replication with Riverbedbackup and data center replication Wide area network-based approaches to data backup are naturally limited by the »»Reduces backup windows and transfer performance of the WAN. Bandwidth limitations and network latency can make backup times to maximize application availability take much longer than desired. For large remote offices with significant datastores, »»Effectively increases WAN capacity by this can make WAN-based backup impossible without significant costly WAN detecting and avoiding the transfer of bandwidth upgrades. repetitive data patterns over the WAN By overcoming bandwidth limitations and optimizing transfers to overcome network »»Boosts TCP performance to hundreds latency, Riverbed Steelhead appliances have successfully enabled and facilitated network- of Mbps to fully-utilize high-speed WAN links based backup approaches in the most demanding customer environments. Riverbed technology dramatically optimizes common network-based approaches for backing up large amounts of data in your distributed enterprise:.

Riverbed optimizes both remote office backup and data center replication across the WAN. Disk-to-Disk backup software simplifies and automates remote office data protection for both desktops and servers, but is often hampered by latency and bandwidth limitations. In addition, once the data is stored centrally on backup servers in the data center, it may be replicated to a separate disaster recovery site. Riverbed can facilitate the replication to the DR site through either Scalable Data Referencing (SDR) technology when using existing WAN links, or through Riverbed's High-Speed TCP capability when using "Long Fat Networks (LFN's)".SOLUTION BRIEF: Network-Based Backup and Data Replication with Riverbed
Centralized Backup and RecoveryToday's enterprises must support employees and computer resources that are distributed throughout the world to meet demands of the global marketplace. When critical data is no longer hosted at just one physical location, the challenge of backing up and securing data is magnified. Traditional approaches involve deploying tape backup equipment and processes to each location hosting data, and hiring or contracting local resources to manage these resources. This can be a tenuous proposition at best, while for some enterprises it is a completely unrealistic option. Network-based backup is the general solution that becomes feasible through Riverbed, in many cases through use of existing WAN links without any bandwidth upgrades. Network-based backup allows for consolidation of data into the data center, where it can be placed onto tape or other secondary storage media. Backup data is then more secure, and easily accessible in the event of a restoration event. Riverbed optimizes the regular transfer of backup data over the WAN into the data center, and accelerates commercial backup software packages by eliminating the transfer of redundant data and minimizing the effects of latency on data transfer. Riverbed's approach eliminates data redundancy across applications or servers as well, going well beyond other data reduction mechanisms found in other storage replication products.
Replication of Centralized Data RepositoriesAn effective disaster recovery strategy requires that all data be stored redundantly at multiple physical locations. In the event of a disaster that destroys data stored at one location, there will always be a second, redundant copy of the lost data at a different physical location. Such a strategy ensures that a single cataclysmic event, such as hurricane, flood,... [download for more]
