We are currently using Tivoli to backup 15 terabytes within our Oracle Database using a RMAN backup script. The RMAN's utility and restoration has been perfect, we have yet to experience any issues. It's very reliable.
Pros
"The restoration and infrastructure is extremely reliable.
"
Cons
"We would like to have the opportunity to omit data from being backed up. For example, we have three virtual machines, each with three disks. When running the backup, it will automatically take each disk rather than allowing us to select what data we want backed.
