To dump your database for backup you call this command on your terminal
mongodump --db database_name --collection collection_name
To import your backup file to mongodb you can use the following command on your terminal
mongorestore --db database_name path_to_bson_file

You can also use gzip for taking backup of one collection and compressing the backup on the fly:
mongodump --db somedb --collection somecollection --out - | gzip > collectiondump.gz
or with a date in the file name:
mongodump --db somedb --collection somecollection --out - | gzip > dump_`date "+%Y-%m-%d"`.gz
Update:
Backup all collections of a database in a date folder. The files are gziped:
mongodump --db somedb --gzip --out /backups/`date +"%Y-%m-%d"`
Or for a single archive:
mongodump --db somedb --gzip --archive > dump_`date "+%Y-%m-%d"`.gz
Or when mongodb is running inside docker:
docker exec <CONTAINER> sh -c 'exec mongodump --db somedb --gzip --archive' > dump_`date "+%Y-%m-%d"`.gz

This command will make a dump of given database in json and bson format.
mongodump -d <database name> -o <target directory>
回答5:
There is a utility called : mongodump On the mongo command line you can type :
>./mongodump
The above will create a dump of all the databases on your localhost. To make dump of a single collection use:
./mongodump --db blog --collection posts
Have a look at : mongodump

You need to open command prompt as an administrator in a folder where your Mongo is installed (in my case: C:\Program Files\MongoDB\Server\3.4\bin). If you want to dump your whole database, you can just use:
mongodump --db database_name
You also have posibilities to dump only certain collection(s), or to dump all but certain collection(s).
If you want to dump only one collection (for example users):
mongodump --db database_name --collection users
If you want to dump all but users collection:
mongodump --db database_name --excludeCollection=users
It is also possible to output the dump to an archive file:
mongodump --archive=test.archive --db database_name

Backup/Restore Mongodb with timing.
Backup:
sudo mongodump --db db_name --out /path_of_your_backup/`date +"%m-%d-%y"`
--db argument for databse name
--out argument for path of output
Restore:
sudo mongorestore --db db_name --drop /path_of_your_backup/01-01-19/db_name/
--drop argument for drop databse before restore
Timing:
You can use crontab for timing backup:
sudo crontab -e
It opens with editor(e.g. nano)
3 3 * * * mongodump --out /path_of_your_backup/`date +"%m-%d-%y"`
backup every day at 03:03 AM
Depending on your MongoDB database sizes you may soon run out of disk space with too many backups. That's why it's also recommended to clean the old backups regularly or to compress them. For example, to delete all the backups older than 7 days you can use the following bash command:
3 1 * * * find /path_of_your_backup/ -mtime +7 -exec rm -rf {} \;
delete all the backups older than 7 days
Good Luck.

You can dump your database and restore with bellow command
mongodb -d <Your_db_name> -o <path of your folder>
for example my database name is tracking i have dump in dump folder
mongodb -d tracking -o dump
Restoring dump
mongorestore -d <databasename> <dum_path>
mongorestore -d tracking dump/tracking

Following command connect to the remote server to dump a database:
<> optional params use them if you need them
- host - host name port
- listening port username
- username of db db
- db name ssl
- secure connection out
output to a created folder with a name
mongodump --host --port --username --db --ssl --password --out _date+"%Y-%m-%d"

cmd -->
C:\Program Files\MongoDB\Server\3.2\bin>mongodump.exe --db Dintest
回答11:
Below command will work to take dump of mongo db .
mongodump -d -o
On Windows : try this one where c:\mongodump is dump file location , It will create metadata in json, and backup in bson format
C:\MongoDB\bin>mongodump -d -o c:\mongodump
回答12:
Or you can make backup script on Windows, remember to add Winrar to %PATH%
bin\mongodump --db=COL1 -o D:\BACK\COL1
rar.exe a -ep1 -r COL1.rar COL1
rename COL1.rar "COL1_%date:~10,4%_%date:~7,2%_%date:~4,2%_%time:~0,2%_%time:~3,2%.rar"
#rmdir /s /q COL1 -> don;t run this on your mongodb/ dir !!!!!
回答13:
Mongo dump and restore with uri to local
mongodump --uri "mongodb://USERNAME:PASSWORD@IP_OR_URL:PORT/DB_NAME" --collection COLLECTION_NAME -o LOCAL_URL
If you do not specify --colletion COLLECTION_NAME, it will dump entire DB.
回答14:
take mongodb backup for particular db and delete 7 days old backup using bin sh command :-
#!/bin/bash
MONGO_DATABASE="nexgtv_16"
APP_NAME="test"
MONGO_HOST="127.0.0.1"
MONGO_PORT="27017"
TIMESTAMP=`date +%F-%H%M`
MONGODUMP_PATH="/usr/bin/mongodump"
BACKUPS_DIR="/home/mongodbbackups/backups/$APP_NAME"
BACKUP_NAME="$APP_NAME-$TIMESTAMP"
$MONGODUMP_PATH -d $MONGO_DATABASE
mkdir -p $BACKUPS_DIR
mv dump $BACKUP_NAME
tar -zcvf $BACKUPS_DIR/$BACKUP_NAME.tgz $BACKUP_NAME
rm -rf $BACKUP_NAME
find /home/mongodbbackups/backups/test/ -mindepth 1 -mtime +7 -delete
回答15:
Use -v to see progress of backup data
mongodump -v --db dbname --out /pathforbackup/NewFolderforBackupData
you can use it for restore also
mongorestore -v --db dbname --drop /pathforbackup/NewFolderforBackupData/dbname
with multile v like -vvvv you will get more information
回答16:
use "path" for windows. Else it gives the error as: positional arguments not allowed
回答17:
mongodump -h hostname -u dbusername -p dbpassword --db dbname --port portnumber --out /path/folder
mongodump -h hostname -u dbusername -p dbpassword --db dbname --port portnumber --out /path/folder.gz
