RE: Questions about bumpsize, frustration

Thanks for your responses, here is a combined answer:
> Is it possible that it needs an update to dump?
I use tar (GNU tar) 1.13.19, not dump.
> Is this happening on all of your machines or just a few?
I'm running amanda on the head node of my cluster, so all the disks are
local. I only back up 1 of my slave nodes (since the others are identical)
and then only parts (/var/log, /usr/spool/PBS, etc.). The problem only
happens on this one machine (itself), but there's not much on any other
machine to back up.
> What version of AMANDA?
Version is amanda-2.4.2p2.
> Do you set record to yes in your dumptype?
Yes, I use "record yes".

-----------------
So yes, each of level 0, 4 and 5 return about the same size from sendsize.
There was about 680M changed last night, so maybe I should look at 8/20
instead. It's just about the same story. The oldest surviving
sendsize.debug is from 8/19. Is there some place I can change a setting to
keep more of these temp files? I can't find it in amanda.conf.

This just tells me amanda has always been confused, through all the levels
of backup.
Hopefully, something in the above sticks out like a sore thumb, and a
lightbulb will go off above someone's head. I sure don't see why sendsize
is so wrong.
