{{Admon/note | Backing up Files |One very important aspect of system admin is performing backups. There are many methods for backing up the data on a a computer system.<br />The following is an example of a common backup system used in Business Unix/Linux systems:<br /><br />'''Full Backup''': Backup all specified files (eg. configuration, data files, etc)<br />'''Incremental Backup''': Backup of only files that have changed since last (full) backup<br /><br />When the system is required to be fully restored, then the '''full backup''' is recovered, followed by each .<br />In this investigation, you will learn how to perform an '''incremental backup''' using the <code>find</code> utility|}}

# Start '''fedora1''' VM and login

Previously, you created a file called <code>/tmp/timestamp</code> that just contains the current date and time prior to running the network configuration toool for fedora2.. Any files that were modified by the GUI network configuration program should have a timestamp later (or newer) than the "timestamp" file you created. All the Linux TCP/IP configuration files are stored under the '''/etc''' directory or its sub-directories. The <code>find</code> command (using the correct options) can be used to only list those files that have been recently created since the timestamp date contained in the <code>/tmp/timestamp</code> file.|}}

{{Admon/tip | Tip | Just for interest, it is relatively simple to automate your backups. You just create a Bash Shell script file using the <code>find</code> command above, give the shell script executable permissions, and use the <code>crontab</code> command to schedule when this script is to be run. If you want to learn more about shell scripting, you can take or refer to the course called '''OPS435''' .}}
