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:

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.
