File Backup

Hi,

I'm trying to write a script that backs-up files to an archive partition. My initial thoughts are that I can launch it from a desktop shortcut, as root user. Here's what I've tried so far:

/usr/local/bin/backup.txt

init 1
rsync -avx /home /archive

As you can see, it copies the /home folder into /archive. Each are on separate partitions. I drop down to init 1, because I figure it will release any locked files and enable them to be copied over. However, after my first attempt, I had to fsck my file system!

So please point me in the right direction before I accidentally electrocute myself, or something even worse happens!!!

Thanks in advance for your replies

Maybe I have to manually drop down to run level 1, using init 1, and then run the script from the command prompt?
