MongoRestore error: "Root directory must be a dump of a single database"

I'm new to MongoDB and I have hard time to backup my local DB and restore it on my server. I found the link on Mongo's website : http://www.mongodb.org/display/DOCS/Import+Export+Tools but I still have problems with the restore.

When I do my backup I call 

mongodump --db Gen

Then I see that all the collections are dump in /bin/dump/Gen folder

I copy-paste from local to the server in the same folder the call

mongorestore --db Gen --drop --dbpath dump/Gen

But I get the following : Error : root directory must be a dump of a single database when specifying a db name with --db

It must be any other directory in a dump directory. So, remove the directory first and re-run the command mongorestore -d db dump/db

This is what ended up working for me (mydb is the name of my database):

mongorestore --drop -db mydb mydbbackup/mydb/

After my mongodump:

mongodump -d mydb -o mydbbackup

Example:

./mongorestore -d db -c mycollection dump/db

will raise the following error

ERROR: ERROR: root directory must be a dump of a single collection
ERROR:        when specifying a collection name with --collection

you can remove the -c option to rolve this error.Beacuse dump/db specify the db, but not collection.

An additional note for whoever doesn't want to be annoyed by the error "root directory must be a dump of a single database when specifying a db name with --db"

When specifying --db and without --collection (restoring a whole database): - the given path must be a directory path - the directory must not contain any other files than .bson or .json. It took me a while to realize that the hidden .svn folder (if you use SVN) will mess up the script

Ok I find out what I'm doing wrong :

I was doing 

mongorestore --db Gen --drop --dbpath dump/Gen

But without the --dbpath it works just fine!

mongorestore --db Gen --drop dump/Gen

Thanks everyone!

I think your folder structure may be getting messed up when you try to move it. For instance, this works for me:

$ ./mongodump --db Gen
$ ./mongorestore --db Gen --drop dump/Gen/

Can you try not moving the dump directory, and restoring from /bin/dump/Gen?

The directory you specify should have .bson files in it, e.g.,

$ ls /bin/dump/Gen
foo.bson  bar.bson  baz.bson
