Serverless Backup System

Serverless backup is also a kind of network-based backup that seeks to limit the role of production servers in backup procedures. The main objective of serverless backup is provide disk-to-tape or disk-to-disk backup without depleting server resources.

Generally, in this duration a production server can devote to processing requests from applications is restricted by the number times it must reserve to repeat data. Removing backup procedures favors the production servers as it frees the servers so it can process more data.

Many serverless backup systems enable provisions like disk-to-tape or disk-to-disk backup, vendors who provide this kind of service may map the copy function slightly differently in comparision. as an example , backup could even be performed by an appliance, which can be an actual physical device or a software function during a bigger storage management product.

                        

A number of companies provide / offer serverless backup services, including Arcserve with its Arcserve Unified Data Protection (UDP), Dell EMC and its NetWorker software and Veritas Technologies' NetBackup appliances. The CA and Veritas products are supported a process mentioned as disk imaging. These applications use an intelligent agent to make a snapshot copy of tips that would the data . The snapshot copy consists of an image of the pointers, which indicate things of the data , but isn't yet a backup of the data itself. the actual backup still must happen, supported the snapshot. The intelligent agent and backup procedures communicate through the Network Data Management Protocol (NDMP).

Another method of performing a serverless backup is via XCOPY, the extended copy function within SCSI. during this case, the server initiates and manages the backup, but isn't involved in actually backing up the data . The SCSI XCOPY command simply tells the data to duplicate from one device or location to a special .
