STS: A Share Taper System for Storage Area Networks

摘要

Data backup is an effective way to protect data. In storage area network (SAN) environments, the traditional data backup method can not meet the needs of data backup. We proposed and implemented a multi-server backup maintenance system Share Taper System (STS). In this system, multi-servers share the tape devices through TCP/IP or Fabric. We also implemented an exclusive lock mechanism based on SCSI-3 to harmonize multi-servers' requirement for tape devices. The test results showed that the STS can effectively improve the utilization of backup systems, and is compatible for isomerous platforms. STS does not require users to update their existing backup software.
