 # 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 --delete /opt/zimbra/ /backup/zimbra

 # 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.
