It might not be spinning if you have enough holding disk that the image
is going there first.  However I gather that's not the case with your
system, so this means taper is not getting any data from the client.
Moving further back in the chain ...

Which matches the above and also says the client is not even trying.

Are you saying the disk is "busy"?  If so, then it's likely tar (or the
OS) is grinding away but not generating any data into the pipeline to
Amanda (sendbackup), as you've already pretty well guessed.

So this is purely a tar (or OS or hardware) issue.  If you did exactly
the same thing by hand that Amanda is asking tar to do, it would act
the same way.  What's going on here is totally independent of Amanda.

Next would be to run truss or a debugger on tar and find out what it's
up to, then talk to those folks.

You upped that value as a workaround for something very, very odd/bad
with the way tar is working on your system.
