# 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.

ROOT_UID=0                              # Only users with $UID 0 have root privileges.
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

# script runs in a loop, snapshots are made of all the images that are currently active inside $VM_DIR
# snapshots will not be conducted on images that are not active
# for machines to be backed up they must be registered and have vmware-tools installed and running on the guest

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