With the increase in business demand, enterprises are considering storing data at a central location, so that the data can be managed and shared between branch offices or clients globally and easily. Applications are becoming centralized and technologies to stream them to users are increasing in popularity. In case of any catastrophe, back up of the data center is a must. Lots of vendors are building up software which can back up data much faster and then compress them to save space. Availability is also a factor that has to be taken into account. Most organizations are building up a secondary data center to maintain continuity in case of any disaster strikes on the primary data center.

Most enterprises have their secondary data center situated approximately 200 miles from the primary data Due to the increasing cost of infrastructure, organizations are looking forward to centralizing their data center to cut cost. This would require less management cost as compared to decentralized data center. Moreover, the WAN architecture is gaining momentum which makes the backup process or remote management of centralized data center easier and faster.
