    Default Structure & force playback of redo log OSS version

    I've searched and can't seem to find anything on the structure of, and how to force the OSS version to replay the redo log. I'm working on a way to script my backups without LVM snapshots or eating up unnecessary amounts of drive space. Can anyone assist? (Note this is the current version 5.0.x (5.0.6)).

    Welcome to the forums,
    So zmrestore, a Network Edition feature (that even allows hot restores of individual accounts) essentially has that ability.

    For reducing backup sizes on the Open Source Edition you might try rsnapshot: Snapshots : Open Source Edition Backup Procedure - Zimbra :: Wiki

    If you're trying to throw something together for FOSS with those redologs, have a look at the new /opt/zimbra/bin/zmplayredo -h
    -Just added via Bug 22659 - ability to replay redologs from arbitrary point in time
    -Mailboxd needs to be stopped to run it.

    You might want to set the below so they go into /opt/zimbra/redolog/archive:
    zmprov ms server.domain.com zimbraRedoLogDeleteOnRollover FALSE
    (On FOSS it's defaulted to TRUE because there are no zmbackup incrementals to process the archives.)

    Some more places to gather info from:
    //depot/zcs/FRANKLIN/ZimbraServer/src/bin/zmplayredo
    //depot/zcs/FRANKLIN/ZimbraServer/src/java/com/zimbra/cs/redolog/RedoLogManager.java
    //depot/zcs/FRANKLIN/ZimbraServer/src/java/com/zimbra/cs/redolog/RedoPlayer.java
    //depot/zcs/FRANKLIN/ZimbraServer/src/java/com/zimbra/cs/redolog/util/ParallelRedoPlayer.java
    //depot/zcs/FRANKLIN/ZimbraServer/src/java/com/zimbra/cs/redolog/util/PlaybackUtil.jav

    For instance if you wanted to search through them you might checkout zmjava com.zimbra.cs.redolog.util.RedoLogVerify
    ie: //depot/zcs/FRANKLIN/ZimbraServer/src/java/com/zimbra/cs/util/RedoLogVerify.java
