What is serverless backup?

Serverless backup is a strategy of offloading backup procedures from a server so that the time ordinarily devoted to backup functions can be employed to carry out other server tasks.A type of LAN free of charge backup that does not use any of the resources of an application server or a backup server.

Serverless backup is primarily an extension of the LAN cost-free backup method. Generally, serverless backup is implemented in a storage area network (SAN) by implementing a information mover appliance, usually a separate device (even though it can also be integrated within the storage device) to manage the backup operations rather than the backup server itself. Rather than LAN, the backup server is straight connected to the backup devices/storage using a fiber channel (FC) or modest personal computer method interface (SCSI interface). An additional approach of serverless backup is via the implementation of disk imaging that uses intelligent agents that point to the backup information sets and then back them up without involving any server in among.

Serverless backup enables disk-to-tape or disk-to-disk backup with no depending on server resources or network bandwidth. The Legato, Veritas, and CA goods are primarily based on a method identified as disk imaging. These applications use an intelligent agent, which makes a snapshot copy of pointers to the data. The snapshot copy consists of an image of the pointers, which indicate the location of the data. The intelligent agent and backup procedures communicate by way of the Network Information Management Protocol (NDMP). The EMC version is primarily based on some thing called a Fastrax data movement platform and Hewlett Packard’s OpenView OmniBak II backup application. Proprietary computer software within the hardware platform is utilized, initial, to mark logical backup objects, and then to back up data on the list.
