OK, Thats another whole issue. I really hope you are doing the DataDumps to a different volume. Doing SQL dumps to a volume then snapping it results in huge snapshots and it pointless (the data is still on the same disks). You are way better off just quiecing the DB and snapping the volume. Ideally with SMSQL or at least with the PrePost Script function of VSC, or a custom workflow in SnapCreator.
