When I backup I would like all my larger size files to be put on the first
part of the tape and work down to the smaller size files toward the end of
the tape. This I believe and hope will provide better tape usage. 

If large size files are dumped last to tape there is a good chance that it
will hit EOT and will then have to start over and a large chunk of tape will
have been wasted and so will time. If smaller size files are sent at the end
then if it does hit EOT not much tape is wasted.

I have been using "SSSSSSSSSS".

So my question:

1) dose Amanda get the size of all the backup files and then figure the
order that it will write to tape?

2) will Amanda get the size of the tape and then figure the order that it
will write files to tape.

3) will Amanda do the dumps in the order that it needs to write to tape.
