# This script will do various backups of Zimbra depending on which you choose,
# most of them are cold backups except the msg backup which hot copies the 'store'
# folder for possible individual mail retrieval. Be sure to change the variables below
# to point to where you got the Zimbra folder and where you want it to be backed up to.
#
# This script must be run as root or a user with equal privileges or it will not work.
#
# When you run this script via crontab be sure to add '> /dev/null 2>&1' at the end
# of the script like below or the tar command will fail for no apparent reason.

#
# As of 2008-04-16 this script uses some extra software to extend this script,
# the scripts standard function will still function without these extra software's but if you
# intend to use this scripts built in file transfer functions you must install the described software below.
#
# Required software: rsync for normal operation and ftp or scp & expect for file transfer capabillities.
