We will soon be starting a migration to eliminate physical tape. We have chosen Luminex to emulate the tape drives and DataDomain to store and deduplicate the data (claimed data reduction of 10x to 30x). We are a small shop and the STK silo (Powderhorn) is at end of life. We have about 30tb of data on tape (exluding the duplexed tapes).
We have to keep data related to the airplanes we build for as long as they are in service (>25 years...) We have no growth because the mainframe is running legacy applications, all new development is on SAP (Unix and Oracle).
