Before running the XtraBackup we do a "ZimbraAccountStatus Maintenance" for all accounts
in sync with LVM Snapshot of /opt/zimbra/store and LDAP Dump.
This makes sure that incoming mails are being queued within the MTA and no MetaData changes occur. 
Also the login is being disabled so that users can not add adresses or Mobile Devices etc.
during the backup time window. The XtraBackup does only take a couple of
minutes for approx. 25G of MySQL. So thats a viable solution for me
provided that the Backup will run 3 am for about 15 Minutes.
