# Comment out the following line if you want to try single cold-sync only
rsync -avogtHK --delete /opt/zimbra/ /mnt/nfsbackup/zimbrabkp/
# 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.
