Chapter 19. Activity Logging

The SysBack log file provides a mechanism to track the completion status of

backup, restore, and verify operations. The log can be used in conjunction with the

progress indicator or file list options, which are used to monitor the ongoing status

of backup, restore, and verify operations.

The sysback log, implemented in a fixed size and in a circular manner, never

grows beyond a specified size. This is called a “head and tail” log. As the log file

grows, the head of the log approaches the tail as if it were a circle. When the head

catches the tail, the log has reached its maximum size and the oldest entries in the

log are purged to make room for new entries. The length of time SysBack log

entries are held is directly related to the maximum size of the log. Increasing the

log size enables the storage of entries for a longer period of time, chronologically.

You can change the default log size and location and also list the log entries.

Accessing the SysBack Logging Menus

To view the SysBack log entries:

1. From the SysBack Main Menu, select Utilities.

2. From the Utilities menu, select SysBack Logging.

Note: At a command line, type smit sb_logging.

Changing the SysBack Logging Attributes (Size and Location)

The SysBack log file (sysback.log) is located, by default, in the /var/adm/ras/

directory. You can change this location, as well as the log size (4096 bytes or 4

Kbytes by default, the minimum size).

You can increase the log size in increments of 4 Kbytes, provided that there is

sufficient space in the log’s destination directory. If you specify to increase the log

size to a number that is not a 4 Kbyte increment, the log size is automatically set to

the next largest multiple of 4 Kbytes. For example, if you specify a size of 4098, the

size will be automatically set to 8192, because 4098 is not a multiple of 4 Kbytes.

To change or show the SysBack logging attributes:

1. From the SysBack Logging menu, select Change/Show SysBack Logging

Attributes.

Note: At a command line, type smit sb_changelog.

2. The following screen is displayed:
