Restore Other Files
Carefully use the same techniques to restore other files and directories,
such as /usr, /local, and /opt. For help in importing entire volume
groups, refer to either HP-UX System Administrator’s Guide or
Managing Superdome Complexes.
The commands cited in this section do not write over newer files, so your
new operating system and any files you update are well protected.
