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
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
