# Updated by Scott Harwell on 02/03/2013 to try to circumvent ldap 85 GB allocated file.
# Also, this backup only backs up locally; ncftp has been commented out.
# Outputs the time the backup started, for log/tracking purposes

# Live sync before stopping Zimbra to minimize sync time with the services down
# Comment out the following line if you want to try single cold-sync only
rsync -avHK –exclude ‘data/ldap/mdb/db’ –delete /opt/zimbra/ /media/backup/zimbra_backup
# which is the same as: /opt/zimbra /backup
# Including –delete option gets rid of files in the dest folder that don’t exist at the src
# this prevents logfile/extraneous bloat from building up overtime.
# Now we need to shut down Zimbra to rsync any files that were/are locked
# whilst backing up when the server was up and running.
