How can I transfer a mongodb database to another machine that cannot see the first one

Question

I have a server that is having trouble talking to the outside world. I would like to get its mongodb contents to another server--but since the servers cannot talk to eachother db.copyDatabase() won't do.

Is there something like mysqldump where I could dump the db into a binary file, scp that somewhere, and then use that to populate another mongodb server?

Answer 1

If you're using Ubuntu/Linux, run the following commands. First, mongodump on the origin server:

mongodump --db DataBaseName 

Copy the generated dump/DataBaseName folder to the new machine. Then, import using mongorestore:

mongorestore --db DataBaseName /path/to/DataBaseName  

Note that /path/to/DataBaseName should be a directory filled with .json and .bson representations of your data.

Answer 2

Use the mongodump and mongorestore commands.

mongodump --db test --collection collection mongorestore --collection collection --db test dump/ 

You can also gzip. The documentation has more examples.
