What command do I use and run?
This question is related to
database
mongodb
database-dump
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
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 !!!!!
This command will make a dump of given database in json and bson format.
mongodump -d <database name> -o <target directory>
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
output to a created folder with a name
mongodump --host --port --username --db --ssl --password --out _date+"%Y-%m-%d"
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
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
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
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
cmd -->
C:\Program Files\MongoDB\Server\3.2\bin>mongodump.exe --db Dintest
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
Omitting --collection COLLECTION_NAME will dump entire DB.
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
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
to export
mongodump -d <database name> <backup-folder>
to import
mongorestore -d <database name> <backup-folder>
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
use "path" for windows else it gives the error as: positional arguments not allowed
If your database in the local system. Then you type the below command. for Linux terminal
mongodump -h SERVER_NAME:PORT -d DATABASE_NAME
If database user and password are there then you below code.
mongodump -h SERVER_NAME:PORT -d DATABASE_NAME -u DATABASE_USER -p PASSWORD
This worked very well in my Linux terminal.
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.
