Doing a CMSADM backup on a mirrored system
3
This section describes how to perform a traditional CMSADM backup on 
a mirrored system. 
Mirroring is intended as a way to minimize data loss should a system crash 
occur, not as a way to avoid backing up data. Mirrored systems must be backed 
up just as often as unmirrored systems.
Step 1: Print the 
vfstab file
3
Print out the contents of the 
vfstab file before beginning the backup. You 
will need the information in that file to restore files from the backup tape.
To print the 
vfstab file, do the following:
1. Enter the following command:
2. Retrieve the printout and save it. You will need it again when the 
backup finishes.
Step 2: Run the 
backup
3
1. At the system console, log in as 
root. 
2. Verify that the computer is in a 
Solaris multi-user state (a run level of 
2
 or 
3
) by entering a 
who -r
 command. The system responds by 
listing the run level and date. For example:
If the system is in some other run level, reboot and log in again as 
the root user:
