You are absolutely right, subsequent level 1 backups do not work.

Please note that you must look very carefully at the exact wording and the
placement of the level description in the documentation.
Full followed by multiple level 1 does function like incremental on normal
(not NDMP) backups and mostlikely NDMP backups, but not with NetApp. You
must consider that the level is passed on to the dump application, and the
NetApp dump command works differently.
Whereas Networker will backup only the changes that occurred since a level
of the same value (simplified explenation) the Ontap dump command does a
backup of all changes since the next lower level (note:

The wording of the Networker manual is differs:

I've been meaning to ask a question about that paragraph, but hadn't gotten
around to it. I don't think that subsequent Level 1 backups will function
like incremental backups. A Level 1 on Day 2 goes back to the Day 1 Full,
but a Level 1 on Day 3 will als o go back to the Day1 Full (including what
had already been backed up on Day 2).

Is this correct?

Thanks,
Randy
