Running OSB version 10.4.0.2 on Solaris11 update 1. When we attempt a client NDMP backup operation the jobs complete but with the following warnings about HW encryption. Does anyone have any idea why we would be seeing this. The backups are being written to a tape drive that is locally attached to the OSB server. The NDMP client does not have any tape devices attached.
Warning: unable to reset encryption - reverting to software encryption.
Turning off encryption. Encryption of NDMP clients requires hardware encryption. hwencdrive=no, hwenctape=no
It wouldn't matter if the tape drive is attached to the NAS or another client in this scenario. At first blush, it appears as though encryption is configured within OSB. As the error message indicates, encrypting NDMP data requires the tape drive to perform the encryption. Another words, OSB cannot use software encryption as OSB isn't installed on the NAS. Are you sure that the backup schedule or default/policy doesn't have encryption on?
