Serverless backup is a method of offloading backup procedures from a server so that the time ordinarily devoted to backup functions can be used to carry out other server tasks. Ordinarily, the amount of time that a server can devote to processing requests from applications is limited by the backup window - the amount of time that must be reserved for data backup. Serverless backup is a storage area network (SAN) solution that is designed to lead to lower hardware costs and improved time-effectiveness, scalability and fault tolerance. A number of companies, including Legato, Veritas, EMC and Computer Associates, offer or are developing serverless backup products.
