After much fighting with slow NAS products, I built a custom NAS server to act as my dedupe store. The new NAS has enough computing power and storage to do IOPS that exceed the local disk on my media server, never mind that of the old NAS devices.
The problem is what to do with my old tape backups and dedupe stores on the older NAS devices. I want to duplicate my backups to the new dedupe store on the new NAS. Most of it is OS backups of multiple virtual machines, which is where dedupe shines, so I don't expect much wasted space.
Copying backup sets from my tapes to the new dedupe store is straightforward, and I can then use the tapes to do disaster recovery backups of the dedupe store. But how do I copy backups from an older dedupe store to another when I can't mount two dedupe stores on the same media server? Can I install another media server and use a temporary license for the server and dedupe store, and then replicate the backup sets between the media servers?
Part of the challenge is the old dedupe stores (there are two) were made on Backup Exec 2010 R3, and the current media server runs BE 2014 SP2. I know I can attach an old dedupe store to a new media server, and it would take some time to convert it, but I'd be OK with that. I imagine inventorying the old stores would take several days, and I'm OK with that too.
