We are looking for Symantec Backup Exec private cloud for our customers, I have been reading though the Backup Exec 2014 Technical White Paper Private Cloud Services & Planning and Deployment Guide. My question is, does it mandatory to use OST supported storage devices at Manaaged Service Provider Backup Exec and the customer Backup Exec Servcer environment as disk repository ? or can we use any storage disk and Dedupication Option license on both ends?
You need Deduplication Storage on both sides of the slow link in order to benefit from optimized duplication.
This can be achieved with Backup Exec Deduplication Storage Folders so you don't need OST supporting hardware. I am not sure however if you can mix technology (i.e. Backup Exec Deduplication Storage on one side and OST Supporting hardware on the other)
