Exercise $1$: Create Backup Files with tar:

Part $1$: Create a Full Backup

Step $1$: Open a terminal window and su to root

Step $2$: Change to the directory$/$srv$/$www

Step $3$: Create a tar archive of the directory htdocs by entering the following: tar czf$/$tmp$/$htdocs$.$tar.gz htdocs

Step $4$: Delete the directory htdocs by entering the following: mm $-$r htdocs

Step $5$: Copy the backup archive to the directory$/$srv$/$www $c\frac{p}{t}m\frac{p}{h}$tdocs.tar.$g\frac{z}{s}r\frac{v}{w}ww$

Step $6$: Restore the directory htdocs by entering the following: tar xzf htdocs.tar.gz

Step $7$: View the content of the restored directory by entering Is htdocs

Take screen shot #$1$ the screenshot of the of the terminal shows all steps from $1$ to $7.$ Make sure to include the name of your host in your screenshot. Multiple screenshots maybe required.

Part $2$: Create an Incremental Backup:

Step $1$: $.$ From the root terminal window, change to the directory$/$srv$/$www by entering the following: cd$/$srv$/$www$.$

Step $2$: Create a full backup by entering the following command:

tar czv $-$g $/$ tmp$/$snapshot$\_$file $-$f$/$tmp$/$htdocs$\_$full.tar.gz htdocs

Step $3$: Create a new file in the directory htdocs by entering the following: touch htdocs$/$incremental$.$html

Step $4$: Perform an incremental backup by entering the following command:

tar czv $-$ g$/$tmp$/$snapshot$\_$file $-$f$/$tmp$/$htdocs$\_$incremental.tar.gz htdocs Note that tar backs up the file incrementally.

Step $5$: View the content of the incremented backup file by entering the following:

tar$-$tzf$/$tmp$/$htdocs$\_$incremental.tar.gz

Step $6$: Remove the directory htdocs by entering the following:

rm$-$r htdocs

Step $7$: Start restoring the directory by unpacking the backup by entering the following:

tar xzf$/$tmp$/$htdocs$\_$full.tar.gz

Step $8$: Unpack the incremental backup by entering the following command:

tar $xz\frac{f}{t}m\frac{p}{h}$tdocs incremental.tar.gz

Take screen shot #$2,$ the screenshot of the terminal shows all steps from $1$ to $8.$ Make sure to include the name of your host in your screenshot. Multiple screenshots maybe required.

Note: Only include the commands that was successfully executed and try to highlight it for better clarity.
