BACKUP CRITICAL SYSTEM FILES

Before modifying critical system files, make a backup copy
using the date as an extension:

$ cp /etc/hosts /etc/hosts.971006

If you keep a number of these they provide a potentially
valuable archive as well as a means of finding out any
changes that have been made and when.
