I was wondering if someone has found a script to backup differential currently im using this script but it does full backup which is a hassle because i have mailboxes of 10-15 gigs which takes a long time
Thank you
Code: Select all
#!/bin/bash
DOMAIN=''
DESTINATION=/opt/zimbra/backup/mailbox
DESTINATION_PREFIX=zmbrbckp
KEEP=5
function help
{
echo "
USAGE
-d, --domain WORD backup accounts with the specified WORD in the name, insert u/domain.ltd for filtering by domain
-f, --folder /PATH/TO/DIRECTORY backup to specified path, default /opt/zimbra/backup/mailbox can be modified in the script file
-k, --keep X keep X previous backups, by default 5. The older backups will be automatically deleted. Has to be integer, the default number can be modified in the script file.
-h, --help display this help

while [[ $# -ge 1 ]]
