-If you have Tiny Core installed on a hard drive, using persistent home and opt, and make extensions for settings, you don't need to use backup.

-If you have Tiny Core installed on a USB drive, using backup, and make extensions for settings and large files, you can have less in backup, which reduces the time taken to start up and shut down the computer, and lengthens the life of the USB drive.

 +==== Examples ====
 +
 +This example will add a shell script to your home directory called "gtt.sh" (for "go to tce"). This contains the line: "cd /mnt/sda1/tce". (see usage below) The new extension shall be called "extpack.tcz". Then open the Terminal and type:
 +
 +<code>mkdir -p /home/tc/extpack/home/tc</code>
 +
 +Now copy your script "gtt.sh" into "/home/tc/extpack/home/tc". Tinycore will copy everything in the "extpack/" directory into its root directory when booting.
 +
 +If you also want to install an application you could make a "usr/local/bin" directory within the "extpack" directory and then put your application into "/home/tc/extpack/usr/local/bin".
 +
 +Now, to make the extension called “extpack.tcz” type:
 +
 +<code>sudo -s
 +cd /home/tc
 +mksquashfs extpack/ extpack.tcz</code>
 +
 +Then copy extpack.tcz into your "tce/optional" directory and add extpack.tcz to your onboot.lst file, e.g. with an editor. When booting, Tinycore Linux will install the extpack.tcz extension and thus copy the gtt.sh script to your "home/tc" directory.
 +
 +Since "cd" is a special case for scripts you have to use the dot command to make this run as expected. So enter ". ./gtt.sh" to execute this script.
 +
 +For another actual example of making an extension for settings, see [[Printer Setup Using Cups]].
 +
 +===Unpack extensions===
 +
 +If you want to update e.g. the extpack.tcz extension in the previous example and do not have the original files available you can unpack the extension using this command:
 +
 +<code>unsquashfs -f -d /home/tc/extpack/ extpack.tcz</code>
 +
 +The documentation for unsquashfs can be found here:
