It is impossible to overstate the importance of preserving your keystore data.
Without access to your keystore you will be unable to decrypt your
encrypted tapes. Please carefully read the topics below to understand the
methods available for protecting your keystore data.
Configuration files
The configuration files allow you to customize the behavior of the
Encryption Key Manager to meet the needs of your organization. These
behavioral choices are described extensively in this document, first in
Chapter 2, “Planning Your Encryption Key Manager Environment,” on
page 2-1, then in the Chapter 4, “Configuring the Encryption Key
Manager,” on page 4-1, and later in Appendix B where the full set of
configuration options is described.
Tape drive table
The tape drive table is used by the Encryption Key Manager to keep track
of the tape devices it supports. The tape drive table is a non-editable,
binary file whose location is specified in the configuration file. You can
change its location to meet your needs.
KeyGroups.xml file
This password-protected file contains the names of all encryption key
groups and the aliases of the encryption keys associated with each key
group.
