NAME

na_backuplog - captures significant events during file system backup/recovery activities.

SYNOPSIS

/etc/log/backup

DESCRIPTION

Filer captures significant dump/restore-related events and the respective times at which they occur. All events are recorded in one-line messages in /etc/log/backup.

The following are the events filer monitors:

Start
Dump/restore starts.

Restart
Restart of a dump/restore.

End
Dump/restore completes successfully.

Abort
The operation aborts.

Error
Dump/restore hits an unexpected event.

Options
Logs the options as users specify.

Tape_open
Output device is opened successfully.

Tape_close
Output device is closed successfully.

Phase_change
As dump/restore completes a stage.

Dump specific events:

Snapshot
When the snapshot is created or located.

Base_dump
When a valid base dump entry is located.

Logging events:

Start_logging Logging begins.

Stop_logging
Logging ends.

Each event record is in the following format:

TYPE TIME_STAMP IDENTIFIER EVENT (EVENT_INFO)

TYPE
Either dmp(dump), rst(restore) or log events.

TIME_STAMP
Shows date and time at which event occurs.

IDENTIFIER
Unique ID for the dump/restore.

EVENT
The event name.

EVENT_INFO
Event specific information.

A typical event record message looks like:

dmp Thu Apr 5 18:54:56 PDT 2001 /vol/vol0/home(5) 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
= Start

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.)

FILES

/etc/log/backup
backup log file for current week. /etc/log/backup.[0-5] backup log files for previous weeks
