Backing up SOHO server

I have freebsd 6.1 installed running Samba authenticating my home users and pc's and home shares for each user. This also serves as a web development box for my internal network. Because there is a login script that runs to map drives on the remote pc's all users are accustomed to dumping there important data there. I am trying to come up with a backup and restore plan. 

Just plan to do complete dumps with the script below once a week which is good for me due to the fact of how the box is used. If a total drive crash happens  I will just reinstall from cd then use restore to recover the dump. I am backing up to a usb drive connected to the server. I have printed the file system and taped it to the top of the usb drive hehehehe.

Any other input would be appreciated. Also on the restore portion I plan to just cd into that slice and run

dd if=/mnt/backup/file/<Backup.gz> |gzip -d |restore -rf -

Since this is for home use and protection for only disasster/drive failure a new install will be done, will retore over write what is there to restore the old contents?
