Exchange EVJournal does not available real time ?

Hi People,

Can anyone here please shed some light for me if there is any way according to the best practice to make sure that the email from Exchange Server journal mailbox is always available for users to be searched through EV search.asp page ?

Because at the moment, in my EV 9.0.4 architecture, it cannot be searched because the EV Backup job is backing up the Open Vault and Index location for 4-5 days mostly during the weekdays.

My assumption is that this EV journal should be instantaneous or nearly real time for any email since it is archiving continuously.

Thanks.
