    Default Incremental backups WAY too big!

    We are using ZCB to backup MySQL db using file backup. We do full backup every 3 hours, incremental on the hour between.

    My full backup only changes by a few hundred MB in those 3 hours. However, the incremental backups are both around 1.5GB!

    Surely ZCB can be smarter about incrementals?

    One strategy here is to create a separate backup set just for backing up binary logs of MySQL. That backup set essentially represents your incremental backups for MySQL.

    We will provide an integrated incremental backup solution for MySQL within ZCB in a future release (along the lines of our ZRM product), which will get rid of the need for above workarounds.
