Combining The Advantages Of Disk And Tape

Corio, a leading global enterprise application service provider, evaluated several different disk backup approaches when their data outgrew their older libraries and drive technology. The addition of disk, according to Corio, would speed up backup and restore, but they also needed to keep tape in the process both for long term retention and off-site disaster recovery.

Corio chose ADIC's Pathlight VX because it offers disk-based backup and the ability to create tapes automatically without requiring a separate process. According to Mike Clark, Sr. Systems Architect at Corio, "Pathlight VX uses integrated data movers to create real export tapes in libraries quickly without using either our SAN or the processors in our storage nodes. And the whole process, including tape export, is initiated and tracked by Legato exactly as it is in a conventional library. We're using both disk and tape, but the whole system looks to Legato like a conventional library." Because Pathlight VX presents itself as a library, it also meant that Corio could leave in place the LAN-based backup architecture they had created to handle their 1,300 servers and four different operating systems.
