data at a different location. If the second token contains a backup of the first token's data, it should
be stored in a secure location, such as a fireproof safe in a different building.
The token data backup file and the second token support several approaches to backing up the
keys so that tapes can continue to be written and read if the first token is lost or destroyed. Choose
an approach that best meets your organization's needs and capabilities.

Highly-reliable file backup and
restore processes that store
backup data off site.
NOTE: If your file backup
process writes encrypted data to
an autoloader or a library using
the encryption kit, be sure to back
up the token data file to a different
removable media, as in the next
case. If the first token is lost or
damaged, you will need the token
backup file to restore onto a token
and you will not be able to restore
the token backup file from the
encrypted tape without a token
with a key for the tape.
Retrieve the token backup

organization's file backup
program and restore it
onto the unused second
token. Back up the token

uninitialized second
token in a secure

Avoids having to retrieve
physical media containing the

location to create a new token
data backup.
•
The token in use does not
need to be removed from the

process.
•
The token backup file can be
restored onto any token.
• The second token does not
need to be stored in a secure

By using a new token for the
restore process, the second
token will have the same
current key to encrypt tapes
as the original token.
