This month I have been working on the evaluation of a VTL (virtual tape library) for our backup environment.

We had a couple initial issues that caused restore problems, but I have since ironed those out and everything appears to be running smoothly.  We are getting very good performance through the VTL we are evaluating right now.  Our only current concern is failover between engines.  This solution runs an active/active configuration and one engine will take over the other engine’s work load in the event that one goes offline.  We had an unplanned production test of this feature a couple of weeks ago that resulted in the hardware locking up and going offline.  It look almost two days to restore service.

Operationally I have been working on fine tuning our backup pools, groups, client priorities, and cloning processes to optimize performance on the VTL.
