Mongorestore of a db causing me trouble

Question

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

Answer 1

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
