You can later change this ID to any other value that might more
accurately describe the backup contents.
Although the filename in SMIT is displayed only as shown above, most backups
actually create more than one file, each named as above, but with an additional
extension. The first file has a .TOC extension, indicating the file is the table of
contents of the backup. For a File/Directory backup, the “.TOC” file also contains
the backup data, because there is always only one image in this backup. For all
other backup types, an additional file is created for each logical volume or
filesystem included in the backup, with the logical volume name as the file
extension. This file contains the actual backup data for each logical volume or
filesystem.
Backup, List, Verify and Restore Command Output Screen
The output screen for the backup, list, verify, and restore options is different from
that of other SMIT-executed commands. This screen provides the following
advantages:
v Output is not saved in the SMIT log file (smit.log). This prevents very long file
lists from taking unnecessary space on the disk. You are still provided the option
of writing the output to a log file after the command has completed.
v There is no delay when the command has completed. The delay is normally
required for SMIT processing and writing of the smit.log file.
v Command output (stdout) and error (stderr) are displayed in separate windows.
This provides much cleaner output for commands that provide both standard
output and standard error messages.
v The complete command and the time the command started and ended is
displayed at the top of the screen.
The following is an example of the output of a file/directory backup executed
from SMIT:
Note that the screen is separated into two windows. The first is for Command
Output (stdout). The second is for Command Error (stderr) and Status. The
