I'm failing miserably to be able to restore a single collection into an existing database. I'm running Ubuntu 14.04 with mongo version 2.6.7 There is a dump/mydbname/contents.bson based off my home directory.
If I run
mongorestore --collection contents --db mydbname Then I get:
connected to: 127.0.0.1 don't know what to do with file [dump] If I add in the path
mongorestore --collection contents --db mydbname --dbpath dump/mydbname Then I get
If you are running a mongod on the same path you should connect to that instead of direct data file access I've tried various other combinations, options, etc. and just can't puzzle it out, so I'm coming to the community for help!

The basic way to restore a database is to use the mongorestore command to specify the backup directory (dump directory) without any options. This option is suitable for databases located in the localhost (127.0. 0.1) using the port 27017.
@Naman what is the use case of copy collection, i mean you need any command or it is ok with manually process? for the manual process just install studio3T connect both databases and right click on collection that you want to copy, click on option "Copy Collection" and then go to second database right click on " ...
I think this is now done with the --nsInclude option:
mongorestore --nsInclude test.purchaseorders dump/
dump/ is the folder with your mongodump data, test is the db, and purchaseorders is the collection.

If you want to restore a single collection then you have to specifiy the dump file of the collection. The dump file of the collection is found in the 'dump/dbname/' folder. So assuming your dump folder is in your current working directory, the command would go something like -
mongorestore --db mydbname --collection mycollection dump/mydbname/mycollection.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!
