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 3 TB media (C7975A or C7975W) and Ultrium 1.6 TB media (C7974A or C7974W). Encrypted Ultrium 3 TB and 1.6 TB tapes can be read on any compatible Tape Blade that supports hardware encryption. (SB3000c Tape Blades can read and write encrypted Ultrium 3 TB media and Ultrium 1.6 TB media; SB1760 Tape Blades can read and write encrypted Ultrium 1.6 TB media.) Hardware encryption is not supported on Ultrium 800 GB and Ultrium 400 GB media. Where can I get more information? For more information about AES encryption, encryption keys, and using hardware encryption with your HPStorageWorks SB3000c and SB1760c Tape Blade, see http://h18006.www1.hp.com/ products/storageworks/lto4Encryp/index.html or refer to the White Papers on http:// h18006.www1.hp.com/storage/tapewhitepapers.html. For detailed instructions about enabling encryption please refer to the documentation supplied with your backup application. This will also highlight any default states, for example when copying tapes, that may need changing if using encrypted tapes. Cleaning the tape drive HP StorageWorks Tape Blade tape drives do not require regular cleaning. An Ultrium universal cleaning cartridge should only be used when the amber Clean LED is flashing. 1. Insert the Ultrium universal cleaning cartridge. 50 Use the correct media
