Hi,
I am testing Zimbra 8 NE (single node). I read in the doc:
MySQL Backup and Restore - Zimbra :: Wiki
"Sites that need an extra level of redundancy for their MySQL data can use the MySQL Binary Log and mysqldump. (...) As of HELIX (version 7.x) of ZCS, there is an option to automatically run full mysqldumps as part of the nightly zmbackup (mysql_backup_retention)"

Sorry for the naive question, but I don't understand why the proper procedure to recover from a mysql crash is not to restore the latest zimbra backup. If mysql is restored, how to be sure that the message store is synchronized with the restored dump?
Thanks,
