Ditto. I’d like to know the problem that you are trying to solve.
Also, as far as I know, amanda does something to every DLE, every time you
run amdump.
It won’t skip the DLE just because no changes have occurred.
You might go up to really odd levels of incremental, if you have even a
week-long cycle. Level 0, 1, 2, 3, 4, 5, 6.
Some might even be empty, if nothing has changed. But it’ll have to create
them anyway.
Unless you tell it your "dumpcycle” is only 4 or 3 days long. Or some such.
And then you are forced to have all of those tapes (vtapes) available for any
backup.
You could possibly do “amadmin config force-bump” every night, in your
cronjob.
Just random thoughts, since we don’t understand the actual problem.
