5. Introduction about project The client–server model is a distributed application structure in computing that partitions tasks or workloads. Clients and servers communicate over a computer network on separate hardware. Both client and server may reside in the same system. A server is a host that is running one or more server programs which share their resources with clients. A client does not share any of its resources, but requests a server's content or service function. Clients initiate communication sessions with servers which await incoming requests. www.engineersportal.in

19. Application Management of data in server storage. Optimizing restore of client data. Backup set enhancement. Simultaneous migration and storage pool backup. Management of reluctant file. Collocation of active data. Expand data backup sets to include data protection product www.engineersportal.in

20. Future Scope Thin client and fat client technologies and web services. Dumb terminals (where used to let the user interact with the processing power of the central mainframe). The availability of fast cheap workstations allowed for a portion of the processing power to be moved to the local workstation. computing power will spread between the end user location and the centralized servers www.engineersportal.in
