Generic vs. Variable Files

To use the backup and restore capabilities of the LCS60 most effectively to protect your system against accidental damage or corruption depends on understanding the difference between generic and variable files. The hard disk of each LCS60 stores both kinds of files. Generic files are the same on every LCS60, and never change. For example, executable programs such as lcsadm are generic files, whereas the TCP/IP configuration file /etc/hosts is a variable file.

In case of system damage or corruption, generic files can be recovered by reinstalling the three generic tapes that are delivered with each LCS60 (see the section Reload System Software in Chapter 9). These tapes cannot be used to recover variable files, however, because variable files are changed during system administration and configuration.

To define the networking parameters (networks, interfaces, etc.) that are unique to each LCS60, the superuser invokes the LCS60's administrative commands and functions to tailor the LCS60 to its networking environment. The definitions, which can be extremely complex, are recorded in the LCS60's variable files, and so are not the same on every LCS60.
