How to Back Up a System
1. Become superuser.
2. Shut down the system.
# init 0
3. Bring the system to run level S (single-user mode).
Use the −s option when you boot the system.
4. (Optional) Check the file system for consistency with the fsck command.
Running the fsck command using the −m option checks for consistency for file
systems. For example, power failure can leave files in an inconsistent state.
# fsck -m /dev/rdsk/device-name
5. If you will be backing up file systems onto a remote tape drive:
a. Add the following entry to the ./rhosts file of the system that is initiating
the backup:
host root
b. Verify that the host name added to the /.rhosts file above is accessible via
the local /etc/inet/hosts file or available NIS or NIS+ name sever.
6. Identify the device name of the tape drive.
The default tape drive is /dev/rmt/0.
7. Insert a tape that is not write protected into the tape drive.
8. Back up file systems using one of ufsdump commands listed in Table 6–3.
