BASE_DATE Species whether a token-based backup is performed. Token-based
backup is used by Tivoli Storage Manager as an alternative to
backups using the LEVEL environment variable. The valid values are:
• -1: Species that token-based backup is disabled
• 0: Species that a token-based backup is performed. After the
backup completes, a token can be retrieved by using the
DUMP_DATE environment variable. This token can then be
passed in a subsequent backup as the value of BASE_DATE. The
backup performed in this case will be an incremental backup
relative to the time when the token was generated.
Backup -1
DEREF_HARD_LINK Species whether hard link les’ data content is backed up for all
instances of the same le. The valid values are Y and N.
