Complete Installation

In some cases, it might be faster to perform a complete reinstallation of the operating system, especially if you install the operating system from a CD and have very few special configurations to recreate. Depending on the speed of your backup device and network, it could potentially take longer to recover the remainder of your files and configurations using Backup during the disaster recovery procedure.

If you use a device with a default configuration that is not directly supported by the operating system, you also need to modify the device configuration files during installation:

• You might need to modify the /kernel/drv/st.conf file to support a DLT tape drive.

• For SunOS systems, modify the /usr/sys/scsi/targets/st_conf.legato.h file.

When you recover the remainder of your data, you can decide whether you want to replace the operating system files you just reinstalled with the operating system files backed up by Backup. If you want to guarantee that you have the same configurations prior to the disaster, replace the files and configurations you created during the installation.
