About Serverless Backup
Serverless Backup is sometimes referred to as Third Party Copy or
Extended Copy (Xcopy). Serverless Backup is a backup architecture in
which data flows directly from one storage device to another, bypassing
the server. Serverless Backup is made possible when storage devices
support the Xcopy commands as specified in the SCSI protocol. The
Xcopy command set allows a device to read blocks of data from another
compliant device. In a Serverless backup environment the Spectra Logic
library reads data from the disk device and writes it directly to tape.
This backup process requires a backup application that has Xcopy
functionality. Serverless backups are normally performed in Storage
Networking environments since data can be shared by multiple hosts or
initiators. The backup application is responsible for determining which
blocks on the disk get backed up to tape.
