First you need a destination for the backups. Let's say it is /backup. It says "important files" and to me that means you pick and choose. For example, out of /etc, maybe passwd, shadow, group, and hosts. There are probably others but all of /etc sounds excessive. Any of /opt also sounds excessive to me. Once the script is working you can tweak the exact file list. Also the exact list will vary from OS to OS and you haven't told us yours.

So it sounds like you cd to /backup, create etc, cd to /backup/etc and copy the files you pick from etc. And repeat this for other directories that have file that you feel are important. cp has an exit status and you will need to check it to see if the cp was successful.

The script should be run out of cron.

I think that this should give you enough ideas to start your script.

NAME
Dkopp - copy files to DVD or BD (Blue-ray) media SYNOPSIS
dkopp [ -job | -run ] jobfile dkopp [ -nogui ] -script scriptfile DESCRIPTION
Dkopp copies files to backup DVD or BD media. It supports full or incremental backups and full or incremental media verification. OVERVIEW
Dkopp is a menu-driven GUI (GTK) program operating in its own window. Dkopp copies files and directories specified in a job file to DVD or BD media. Dkopp can copy all files to empty media (full copy), or only new and modified files to previously used media (incremental). Files and directories to include or exclude can be selected from the file system hierarchy using a GUI navigator. Specifications are saved in a job file which can be re-edited and re-used. Script files can be run in batch mode using the -nogui option. Dkopp can be used to select and restore files previously copied, and owner and permission data is also restored. The DVD/BD media can also be accessed with file system tools like Nautilus. Dkopp supports the following functionalities: - Three backup modes: full, incremental, accumulate. - Three media verification modes: full, incremental, thorough. - Use write-once or re-writable DVD or BD media (but not CD). - Report disk:backup differences in detail or summary form. - Select and restore files from a backup copy (or use drag and drop). - Search log files to find media where specified files are saved. OPTIONS
Command line options: [ -job ] jobfile open job file for editing -run jobfile execute a job file [ -nogui ] -script scriptfile execute a script file SEE ALSO
The online user manual is available using the menu Help > contents. This manual explains Dkopp operation in great detail. Dkopp uses the batch programs grwoisofs and genisoimage. Dkopp is essentially a GUI front-end for these programs. AUTHORS
