Subversion Repo Backup

Okay, I've successfully gotten a shell script running that will dump all of my subversion repositories to both a shared folder, and a USB hard drive. I largely made use of the example from this site: http://www.hossainkhan.info/content/shell-script-backup-all-your-svn-repositories

The meat of the script is below:

#!/bin/sh
 
# Record todays date
# --------------------
bakdate=$(date +"%Y-%m-%d %H;%M;%S")
echo "--------------------------------"
echo "Running SVN backup $bakdate"
echo "--------------------------------"
 
# From where to backup repos?
# ---------------------------
svnrepos="/opt/subversion"
echo "Going to backup all SVN repos located at: $svnrepos"
 
# Where to save the dump?
# ------------------------
bakdest="/Engineering/ENGR ADMIN/SVN Dumps"
bakfolder="$bakdest/$bakdate"
 
# Location for USB drive? (to copy backup)
# ----------------------------------------
baktousb="/USB_HDD_1/svn"
baktousbfolder="$baktousb/$bakdate"

 
# _________NO-COFIG-REQUIRED-BELOW-THIS-LINE___________
 
# First go to SVN repo folder
cd $svnrepos

# Just make sure we have write access to backup-folder
if [ -d "$bakdest" ] && [ -w "$bakdest" ] ; then
	mkdir "$bakfolder"
	# Now $repo has folder names = project names
	for repo in *; do
		# Do svn dump for each project
		echo "Taking backup/svndump for: $repo"
		echo "Executing : svnadmin dump $repo > $bakfolder/$repo-$bakdate.svn.dump"
		# Now finally execute the backup
		svnadmin dump $repo > "$bakfolder/$repo-$bakdate.svn.dump"
		
		# You can go the extra mile by applying tar-gz copmression to svn-dumps
		#svnadmin dump $repo --deltas | gzip > "$bakfolder/$repo-$bakdate.svn.dump.gz"

		# We also would like to save the dump to remote place/USB
		if [ -d "$baktousb" ] && [ -w "$baktousb" ] ; then
			#USB/other directory exists, copy the dump there
			mkdir -p "$baktousbfolder"
			echo "Going to copy $repo dump to $baktousb directory..."
			cp "$bakfolder/$repo-$bakdate.svn.dump" "$baktousbfolder"
		fi
	done
else
	echo "Unable to continue SVN backup process."
	echo "$bakdest is *NOT* a directory or you do not have write permission."
fi
 
# End of backup script
echo "================================="
echo " SVN Backup Complete!"
echo "================================="
echo " - Backup Complete, THANK YOU :-]"

However, I've run into some problems in trying to automate it. I want to do daily backups, so I named this file svnbackup_cron (with no extension) and placed it in the cron.daily folder. If I log in as root and run the script manually, it executes without any problem. However, when it runs automatically, it only dumps the contents of five of my seven repositories. And, it only copies four of those to the USB drive. I've checked for errors in /var/log/cron.log and didn't see any.

What might be going on here? I haven't been able to find anything out by googling.
