System Files Backup in Ubuntu 9.04

A quick note on the rsync command I used to make a backup of my system files in Ubuntu 9.04.   I already had a TIB file backup made with Acronis True Image, but it was a month old and I figured the individual files would be more accessible anyway if I just copied them straight over to another drive. The command I used for this was as follows:

sudo rsync -qhlEtrip --progress --delete-after --ignore-errors --force / "/media/BACKUP/Ubuntu System Files"

where BACKUP was the name of a hard drive partition.
