    Default Manual /opt/zimbra/store deduplication

    Hello.

    I just synchronized mail from ZCS 5 to ZCS 7 using imapsync and I noticed that mail stored on the ZCS 7 host is not deduplicated. I want to confirm, is manually hard linking all the files in /opt/zimbra/store sufficient for deduplication?

    I've taken a look at the MySQL database and it seems duplicate messages can be tracked using mboxgroup.mail_item.blob_digest. I don't need to be concerned with records in the MySQL database becoming corrupted when doing so, right?

    There are already several threads on this in the forum, with some tools suggestions.

    Yes, I saw them before I posted this question. As far as I can tell, they all just hard link everything. I just want to confirm that nothing has changed in ZCS 7 and I can just hard link everything without having to be concerned about records in the database becoming corrupted.

    Ok guess I'll just have to go ahead, do it, and cross my fingers hoping that I've checked everything that I could. Thanks!
