How do I create a MongoDB dump of my database?

Question

What command do I use and run?

Answer 1

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 !!!!!

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

This command will make a dump of given database in json and bson format.

mongodump -d <database name> -o <target directory>

Answer 6

to export

mongodump -d <database name> <backup-folder>

to import

mongorestore -d <database name> <backup-folder>
