Say you want to transfer your local mongo dbs to another machine.  One way using dump and restore is:

1. run mongodump on old machine
- this will put all your mongo dbs in a directory called dump in the current dir
- for instance if you have one db called mydb, will have a dir dumb/mydb with your data

2. zip and transfer dump dir to new machine

3. after unzipping run mongorestore from the dir containing dump:
- e.g. to restore the db in step 1, do:
mongorestore --db db_to_restore dump/mydb

(where of course you sub your db name for mydb)

Note:
mongorestore will create a new db in named db doesn't exist.  If it exists, it will add records which don't already exist.  It will not update existing records.
