    Description

      Perform dump with compression...

      $ mongodump -dtest --gzip
      2015-06-22T14:36:40.019-0400	writing test.system.indexes to dump/test/system.indexes.bson
      2015-06-22T14:36:40.021-0400	writing test.a to dump/test/a.bson
      2015-06-22T14:36:40.021-0400	writing test.b to dump/test/b.bson
      2015-06-22T14:36:40.023-0400	done dumping test.a
      2015-06-22T14:36:40.023-0400	done dumping test.b
      

      ...view directory files produced:

      $ ls -al dump/test/
      total 68K
      drwxrwxr-x 2 wisdom wisdom 4.0K Jun 22 14:36 ./
      drwxrwxr-x 3 wisdom wisdom 4.0K Jun 22 14:36 ../
      -rw-rw-r-- 1 wisdom wisdom   47 Jun 22 14:36 a.bson.gz
      -rw-rw-r-- 1 wisdom wisdom   93 Jun 22 14:36 a.metadata.json.gz
      -rw-rw-r-- 1 wisdom wisdom   47 Jun 22 14:36 b.bson.gz
      -rw-rw-r-- 1 wisdom wisdom   93 Jun 22 14:36 b.metadata.json.gz
      -rw-rw-r-- 1 wisdom wisdom   79 Jun 22 14:36 system.indexes.bson.gz
      


      Note the absence of the .gz suffix.

      It would also be helpful if during restore, we produced a helpful error message when a user attempts to restore compressed data without supplying --gzip

      $ mongorestore
