Today I’ve setup a cold backup routine to backup my Zimba installation running on my Debian (Etch) 4.0 server that is in full production now for my private domains. This is a slightly modified backup script for the Open Source Edition of Zimbra from the Zimbra Wiki. Please note that the script does a full backup every time it’s being run!
#!/bin/bash # Zimbra Backup Script # Requires sftp to run # This script is intended to run from the crontab as root # Free to use and free of any warranty! Daniel W. Martin, 9 Sept 2007 # 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. # Stop Zimbra Services sudo -u zimbra /opt/zimbra/bin/zmcontrol stop sleep 40 # Sync to backup directory rsync -avHK --delete /opt/zimbra/ /backup/zimbra # Restart Zimbra Services sudo -u zimbra /opt/zimbra/bin/zmcontrol start # Create a txt file in the backup directory that'll contain the current Zimbra # server version. Handy for knowing what version of Zimbra a backup can be restored to. sudo -u zimbra zmcontrol -v > /backup/zimbra/conf/zimbra_version.txt # or examine your /opt/zimbra/.install_history # Create archive of backed-up directory for offsite transfer # cd /backup/zimbra ZimbraVersion=zimbraBackup-zcs-5.0.1_GA_1902.DEBIAN4.0.20080109200914 tar -zcf /backup/$ZimbraVersion-$(date +"%Y-%m-%d").tgz -C /backup/zimbra . # Transfer file to backup server using passwordless sftp scp zimbraBackup-zcs-5.0.1_GA_1902.DEBIAN4.0.20080109200914-$(date +"%Y-%m-%d").tgz email@example.com:/path/to/backupfolder/
I’ve described passwordless ssh/sftp session in a earlier post so I won’t describe the last line of the backup script.
