It won't answer all your questions, but if you look in the Amanda logs
on the client side you can find inside the "runtar" log the exact
"tar" command that Amanda is using. This will tell you, for example,
how the "include" and "exclude" options are being processed together.
As far as experimenting with the sizes of different DLEs: If you have
"estimate client", then the runtar log that has a date stamp
corresponding to the "sendsize" log file will have the command Amanda
uses to generate the estimate, something like:
1491892205.874623: runtar: running: /bin/tar --create --file /dev/null
--numeric-owner --directory / --one-file-system --listed-incremental
/var/lib/amanda/gnutar-lists/rushey__0.new --sparse --ignore-failed-read
--totals --exclude-from /tmp/amanda/sendsize._.20170411023005.exclude .
You would want to point --listed-incremental at your own scratch file,
and perhaps point --exclude-from at a manually-edited a copy of the
*.exclude file as you tried various combinations of excluded
directories, but you should be able to run a version of the command
manually and see the resulting size totals that Amanda would have
obtained for its estimate (i.e. without having to kick off the full dump
run).
(If you switch to the amgtar application, you'll find the equivalent
information in the "amgtar.*" log files.)
I don't know about Cygwin, but if you are using the "PC backups using Samba"
DLE syntax, the smbclient command used for that estimate will be found
directly in the "sendsize" log file, something like:
1491633079.015089: sendsize: Spawning "/usr/bin/smbclient smbclient
"\\\\HOSTNAME\\Finances" -d 0 -U backup -E -W WORKGROUP -c "archive
0;recurse;du"" in pipeline
(In general I think it is safe to say that that this behind-the-scenes
smblicent invocation will not behave exactly the way you would expect
Unix to work -- but looking at the smbclient command line and man page
should at least help you figure out what is actually happening....)
