What Does Serverless Backup Mean?
Serverless backup is a type of backup process that saves data and files without using the computational resources of the backup server. It enables data backup while eliminating the degradation of the network bandwidth and server response time. Serverless backup is also known as server-free backup.
Techopedia Explains Serverless Backup
Serverless backup is primarily an extension of the LAN free backup process. Typically, serverless backup is implemented in a storage area network (SAN) by implementing a data mover appliance, usually a separate device (although 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 directly connected to the backup devices/storage using a fiber channel (FC) or small computer system interface (SCSI interface). Another method of serverless backup is through the implementation of disk imaging that uses intelligent agents that point to the backup data sets and then back them up without involving any server in between.
