Newbie Backup Script
Hello All,

I have attempted to write my first complex (to me) backup script. I am offering it to any and all who may find it useful but would like to refine it as well. I'm using it to backup a Mac OSX Lion Server to a USB Raid5. The script is actually comprised of a daily and a weekly script called by a plist file. Please provide any and all comments, corrections etc. Thanks in advance

I see posibly two issues; the device disk number could change and the uncanny ability of OS X to write directorties that aren't mount point to the /Volumes directory. So first I would query diskutil and mount for the proper device then run something like ->
Code:
for MNT in /Volumes/*
do
if [[ $(/usr/bin/stat -f "%d" "$MNT") = $(/usr/bin/stat -f "%d" "$MNT/..") ]]; then
 echo $MNT is NOT a file system mount point
fi
done

add this line to the top somewhere.
Quote:
# The script must be run as root
#
if [ "$USER" != "root" ]; then
echo "Must be run as root"
exit 1
fi
