Examine Key Files 
The scripts used during the upgrade are designed to back up the key files most likely 
to be found on the DNCS. Some sites, however, include special key files that are 
unique to that site, only. As part of the backup, the upgrade scripts ask if you have 
any special files that you want to be added to the list of files to be backed up. When 
you answer yes, the system offers you an opportunity to add additional files and 
directories to the default key files list.  
The list of default key files is located on the installation DVD in the following file: 
/cdrom/cdrom/sai/backup_restore/keyFiles.include
 
With SR 5.0 you may now create a file containing the list of absolute paths to 
files/directories you want to be added to the default key files list. You only have to 
supply the path to this file and the upgrade will read the contents of the file and add 
those paths to the default key files list. 
Important:  The file we create for this example is called keyfiles.out. You can create a 
file name of your choice to maintain your system key files. The content of your file 
will differ from the example. 
Example file: 
$ less /export/home/dncs/keyfiles.out 
/export/home/dncs/network 
/export/home/dncs/tmp 
/export/home/dncs/keyfiles.out 
/dvs/backups/DBbackups 
Important:  You can save a lot of time if you spend a few minutes identifying those 
special files now. Work with the system operator to determine if there are any 
special files or scripts that need to be backed up. 
 
Identify Special Files to be Backed Up 
On a sheet of paper, create a list of special key files that you will back up. Use the 
following guidelines when you create the list:  
 
Make a list of all custom scripts that your system uses.  
 
Review all system cron files and write down any special cron files that you want 
to retain after the upgrade.
