Well I have been working an issue with their support for 2 weeks now and it seems there is a bug in 5.9 that casues backed up data to get lost when you migrate to 6.1. Their answer is "opps sorry, we had a bug and your backup data is loast, nothing we can do!". Typical Commvault crap. Their software is buggy and quirky and their support is weak. These guys should not be playing in the Enterprise space.
