Backing Up Files and File Systems Before You Install

Once you decide which files or file systems you need to back up from the SunOS release 4, you can use the standard commands and procedures given in the SunOS release 4 documentation to do backups. The command you use depends on whether the tape drive is local or remote. No matter how you plan to handle the data transfer, it is still a good idea to back up all disk partitions by doing full dumps before you begin the installation process.
