Has anyone tried the approach of only flushing full dumps and leaving
incremental dumps on disk? I think that this would have roughly the same
effect as doing full dumps out of cycle, but I have not had luck so far
with the out-of-cycle approach. I think that it should be fairly easy to
script, create a parallel directory tree and temporarily move out the
incremental dumps that you don't want to flush, for example.
The idea would be to leave all of the incremental dumps available on a
huge disk, but keep all of the full dumps on tape, so at most one tape
should be required for any restore. Since the full dumps take up the
most space, clearing them out should leave more space for a longer
history of incrementals. At least that is the idea.
