Ubuntu Networking :: Cron Not Work When Trying To Sync With Network Drive?

Cron refuses to work when trying to sync with a network drive. I am trying to setup a cron job to backup a folder in my home directory ('/home/scratch') to a folder ('home/internet_backup') that is mounted (using nfs) to a network folder. The folder ('home/internet_backup') is mounted correctly to the network folder upon system startup, so this part works.

I created a simple bash file (rsync-shell.1.sh) that looks like this:
Code:
# backup the contents of 'scratch' (of 'internet' machine) into '/home/aa/internet_backup/'
# the latter folder ('/home/aa/internet_backup/') is mounted to 'developer' machine
rsync -av --exclude=".*" /home/aa/scratch /home/aa/internet_backup/
#

When manually running this bash file from my home directory (./rsync-shell.1.sh) everything works, and the contents are written to the destination folder. Yet, instead of running this manually, I wanted this to be executed by Cron every 30 min. so I first chmod +x this file, and then copied it (using sudo) to /root.

I then created the following using 'sudo crontab -e':
Code:
# m h dom mon dow command
10 * * * * /root/rsync-shell.1.sh
This is the same bash file illustrated above, yet, it doesn't work (files are not being written to the destination folder).
