问题
I have separate development and production MongoDB servers and I want to keep actual data in development server for sometime. What I should use for it: mongodump, mongoimport or something else?
Clarification: I want to copy data from production to development.
回答1:
You can use the db.copyDatabase(...) or db.cloneDatabase(...) commands:
http://www.mongodb.org/display/DOCS/Copy+Database+Commands
This is faster than mongodump / mongorestore because it skips creating the bson representation on disk.

If it's a one time-thing
and you want fine control over parameters such as which collections to sync, you should use:
- mongodump to dump bson files of your Production DB to your local machine
- mongorestore to then, retrieve the dumped BSON files in your Local DB
Otherwise you should check out mongo-sync
It's a script I wrote for my self when I had to constantly copy my Local MongoDB database to and from my Production DB for a Project (I know it's stupid).
Once you put your DB details in config.yml, you can start syncing using two simple commands:
./mongo-sync push # Push DB to Remote
./mongo-sync pull # Pull DB to Local
If you use it inside some project, it's a good idea to add config.yml to .gitignore

When you want the dev database to look exactly like the production database, you can just copy the files. I am currently running a setup where I synchronize my MongoDB database between my desktop and my notebook with dropbox - even that works flawless.
