On FreeBSD 5.4-R, I did a backup using 4 dump/restores and each
dump (-0L) gave two scary-looking lines like those that stick out here:

  ...
  DUMP: estimated 71239 tape blocks.
  DUMP: dumping (Pass III) [directories]
  DUMP: dumping (Pass IV) [regular files]
warning: ./.snap: File exists
expected next file 4037, got 180
  DUMP: DUMP: 72413 tape blocks
  DUMP: finished in 10 seconds, throughput 7241 KBytes/sec
  ...

1) Why should "dump" warn about "./.snap" when the manpage implies
that not having one is a problem that it explains how to fix?

2) What's the "expected" line trying to tell me?  I can guess that
"file 4037" means "inode 4037", but I don't know what I'm supposed to
do with this information.  One could worry that the dump was bad.
Should it be telling me things like that?  What could the manpage say
to explain such a message?

Thanks.
