Description: Here I have uploaded Backup script for Zimbra with Rsync Over SSH
#!/bin/bash # Zimbra Backup Script # For Rsync need to configure password less ssh between two Server
# https://systemadmintalk.blogspot.com/2016/10/password-less-ssh-connection-between.html # This script is intended to run from the crontab as root # Local Server Directory Path DESTLOCAL=/Backup/zimbra_backup # Remote Server Directory path DESTREMOTE="root@10.10.10.10:/home/Zimbra_Server_Backup" # Outputs the time the backup started, for log/tracking purposes echo Time backup started = $(date +%T) before="$(date +%s)"
# a backup dir on the local machine. This will fill up over time!
BACKUPDIR=$DESTLOCAL/$(date +%F-%H-%M-%S)
# 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.
before2="$(date +%s)"
# Stop Zimbra Services
/etc/init.d/zimbra stop
#su - zimbra -c"/opt/zimbra/bin/zmcontrol stop"
#sleep 15
# Kill any orphaned Zimbra processes
#kill -9 `ps -u zimbra -o "pid="`
pkill -9 -u zimbra
# Only enable the following command if you need all Zimbra user owned
# processes to be killed before syncing
# ps auxww | awk '{print $1" "$2}' | grep zimbra | kill -9 `awk '{print $2}'`
# Sync to backup directory
rsync -avHK --delete --backup --backup-dir=$BACKUPDIR /opt/zimbra/ $DESTLOCAL/zimbra
