We're running CV v8, and would like to enable hardware encryption on
LTO4 drives. One concern we have is how we could recover data in the
event of a disaster. Looking at the doc under "Hardware Encryption", I
see the following note:
For each data protection operation, the software checks the drive to
see if encryption is supported. If encryption is supported, the
software provides the encryption key, which is in turn stored in the
CommServe Database Engine when the chunk is written to the media. The
encryption key will be stored after scrambling it with a proprietary
encryption.
For Data Recovery and Auxiliary Copy operations using the CommCell
Console, the specific key will be automatically provided by the
software for each chunk.
For Data Recovery operations using the Media Explorer, an option to
store the encryption key on the media is provided in the data path.
Q1) If we were to ever need Media Explorer, wouldn't the option to store
the key on the media defeat the purpose of encryption? Or am I missing
something?
Q2) I know that the manual recommends AGAINST encrypting and compressing
data via software since compressing encrypted may actually result in
larger data. Is this a valid concern when using Hardware compression and
encryption as well?
