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
If you are unable to supply the key when requested to do so, neither you
nor Technical 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.
You should keep a record or backup of your
Warning
encryption keys and store them in a secure place
separate from the computer running the backup
software.
Hardware encryption can be used with or without compression and without
speed or capacity penalties.
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.
