# NOTES: This script runs in a loop, backing up all the images of machines runnng inside $VM_DIR
# machines to be backed up must be registered. To register an image as root execute the command
# vmware-cmd -s register "/disk2/Virtural_Machines/mail01.theglaserfamily.org/mail01.theglaserfamily.org.vmx" 
# replace mail01.theglaserfamily.org.vmx with you image file.
# This script also requires that you vmware-config-tools running inside the guest for the script
# to execute properly.

VM_DIR=/disk2/Virtural_Machines/        # Path to virtural machines, this will vary based on you installation.
VM_IMAGE=mail01.theglaserfamily.org     # Name/Directory of the virtural machine image
BU_PATH=/disk2/backups                  # Path to the backup directory
TMP_LOC=$BU_PATH/tmp/                   # Path to make tmp copies this directory must exist prior to running script
SSHID=sglaser				# SSHID ??
USER=sglaser				# Username of the account to use for SSH
HOST=kermit				# Host name of the machine to be copied to

# needs one parameter (dir of image to back up)
# Copy routine will determine the state of the node, based on that it will either copy or not copy the data.
