NOTE:
Encryption with keys that are generated directly from passwords or passphrases may be less secure than
encryption using truly random keys. Your application should explain the options and methods that are
available. Please refer to your application’s user documentation for more information.
How do I enable encryption?
Hardware encryption is turned off by default and is switched on by settings in your backup application,
where you also generate and supply the encryption key. Your backup application must support hardware
encryption for this feature to work. The software supplied with the tape drive provides this support.
See http://h18004.www1.hp.com/products/blades/components/c-class-storageworks.html for an
up-to-date list of other suitable backup software.
When will I be asked to enter the key?
Encryption is primarily designed to protect the media once it is of fl ine and to prevent it being accessed
from another machine. You will be able to read and append the encrypted media without being
prompted for a key as long as it is being accessed by the machine and application that fi rst encrypted it.
There are two main instances when you will need to know the key:
• If you try to import the media to another machine or another instance of the backup application
• If you are recovering your system after a disaster
What happens if I don’t remember the key?
CAUTION:
You should keep a record or backup of your encryption keys and store them in a secure place separate
from the computer running the backup software. If you are unable to supply the key when requested to
do so, neither you nor HP Support will be able to access the encrypted data.
This guarantees the security of your data, but also means that you must be careful in the management
of the encryption key used to generate the tape.
Does encryption affect tape drive performance?
Hardware encryption can be used with or without compression and without speed or capacity penalties.
Does the tape drive encrypt media in an earlier Ultrium format?
No. Encryption is supported only on Ultrium 1.6 TB media (C7974A or C7974W).
Ultrium 1.6 TB tapes encrypted on an HP StorageWorks SB1760c Tape Blade can be read on any
compatible HP StorageWorks SB1760c Tape Blade (or Ultrium 1760 or Ultrium 1840 tape drive) that
supports hardware encryption.
HP StorageWorks SB1760c Tape Blades can read Ultrium 800 GB and Ultrium 400 GB media and write
Ultrium 800 GB media, but hardware encryption is not supported on these formats.
