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

No. From mongorestore: If you restore to an existing database, mongorestore will only insert into the existing database, and does not perform updates of any kind. If existing documents have the same value _id field in the target database and collection, mongorestore will not overwrite those documents.
mongorestore is a simple utility that is used to restore backups. It can load data from either: A database dump file created by the mongodump command. The standard input to a mongod or mongos instance.
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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
