Using tape for NetBackup Accelerator backup?
As you may already know, NetBackup Accelerator does not currently support backup to tape. It has to go to OptimizedSynthetic-capable storage units such as NetBackup PureDisk, Cloud storage plug-ins, and qualified OpenStorage devices.
The NetBackup Accelerator framework however, doesn't extend to duplication, so you can duplicate the image to tape, either manually or automatically via Storage Lifecycle Policy. No extra configuration is necessary and data can be restored from either original copy or duplicate copy as per normal as long as they have not expired.
