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.
WARNING! Keep a record or backup of your encryption keys and store them in a secure place
separate from the computer running the backup software.
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?
Encryption is supported only on LTO-6 Ultrium 6.25 TB media (C7976A or C7976W), LTO-5
Ultrium 3 TB media (C7975A or C7975W) and LTO-4 Ultrium 1.6 TB media (C7974A or C7974W).
Encrypted LTO Ultrium 6.25 TB, 3 TB, and 1.6 TB tapes can be read on any compatible Ultrium
tape drive that supports hardware encryption.
•
LTO-6 Ultrium tape drives can read and write encrypted LTO-6 Ultrium 6.25 TB media and
Ultrium 3 TB media; they can read Ultrium 1.6 TB media.
•
LTO-5 Ultrium tape drives can read and write encrypted LTO-5 Ultrium 3 TB media and
Ultrium 1.6 TB media.
•
LTO-4 Ultrium tape drives can read and write encrypted LTO-4 Ultrium 1.6 TB media.
Hardware encryption is not supported on any earlier Ultrium media, such as LTO-3 Ultrium 800
GB and LTO-2 Ultrium 400 GB.
Where can I get more information?
For more information about AES encryption, encryption keys, and using hardware encryption
with your LTO Ultrium tape drive, see the White Papers on
http://www.hpe.com/info/enterprise/
docs .
For detailed instructions about enabling encryption, refer to the documentation supplied with your
backup application. This documentation will also highlight any default states, for example when
copying tapes, that may need changing if using encrypted tapes.
Write protecting cartridges
WARNING! Always remove the cartridge from the tape drive before you change the write
protection.
If you want to protect the data on a cartridge from being altered or overwritten, you can write
protect the cartridge.
•
To write protect a cartridge, push the switch to the right to prevent any data recording on
the cartridge. Note the padlock on the tab that indicates that the cartridge is protected.
•
To write enable a cartridge, push the switch to the left to allow data recording on the cartridge.
The following figure illustrates the location of the write-protect tab.
