The value of tmnxLogFileIdBackupLoc specifies where the log
or billing file should be created if it cannot be created in
the location specified by tmnxLogFileIdAdminLocation. The file
location should be a compact flash on the primary CPM. When the
secondary CPM becomes the primary CPM after a failure, the same
log file policies will be activated. Thus it is recommended that
the same media is available to both secondary and primary CPMs.
If no backup location is specified, 0, and the log or billing
file could not be created in the location specified by
tmnxLogFileIdAdminLocation or the file creation at the specified
backup location fails, a file create failure trap is issued
and the associated log or accounting policy is marked as
operationally 'outOfService'.
