      to repro:

      1) start up a mongod with --storageEngine=wiredTiger
      2) insert some data
      3) shut it down.
      4) use the "wt" command to try to generate a backup:

      ./wt -C "extensions=[./ext/compressors/snappy/.libs/libwiredtiger_snappy.so]" -h /data/db/copied_path2/ backup /tmp
lt-wt: /data/db/copied_path2//WiredTigerLog.0000000011: No such file or directory

      The file that it looks for is actually in journal/ within the specified path, but the WT command won't look in there. It still won't work even when trying to specifically point it to journal/ :

      $ ./wt -C "extensions=[./ext/compressors/snappy/.libs/libwiredtiger_snappy.so],log=(path=journal)" -h /data/db/copied_path2 backup /tmp/
lt-wt: /data/db/copied_path2/WiredTigerLog.0000000015: No such file or directory

$ ./wt -C "extensions=[./ext/compressors/snappy/.libs/libwiredtiger_snappy.so]" -h /data/db/copied_path2/journal backup /tmp/

lt-wt: No such file or directory
