Each event record is in the following format:

A typical event record message looks like:

Start (level 0, NDMP)
In the particular example:
-
TYPE
- = dmp
-
TIME_STAMP
- = Thu Apr 5 18:54:56 PDT 2001
-
IDENTIFER
- = /vol/vol0/home(5)
-
EVENT

-
EVENT_INFO
- = level 0, NDMP
All event messages go to /etc/log/backup. On every Sunday
at 00:00, backup is roated to backup.0 and backup.0 is
moved to backup.1 and so on. Up to 6 log files(spanning
up to 6 weeks) are kept.
The registry option backup.log.enable controls the
enabling and disabling of the logging with values on and
off respectively. The functionality is enabled by
default. (See na_options(1) for how to set options.)
