and use. LTO-5 tape drives use the strongest version of the industry-

standard AES encrypting algorithm to protect your data.

To make use of this feature you need:

• A backup application that supports hardware encryption

• Ultrium 3TB media or Ultrium 1.6TB media; no encryption will be

performed when writing earlier generations of tape

When should I use

encryption?

Your company policy will determine when you need to use encryption.

For example, it may be mandatory for company confidential and

financial data, but not for personal data. Company policy will also

define how encryption keys should be generated and managed. Backup

applications that support encryption will generate a key for you or allow

you to enter a key manually.

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.

When will I be asked to

enter the key?

Encryption is primarily designed to protect the media once it is offline

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

first 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
