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
您还可以gzip
用于备份一个集合并即时压缩备份:
mongodump --db somedb --collection somecollection --out - | gzip > collectiondump.gz
或在文件名中带有日期:
mongodump --db somedb --collection somecollection --out - | gzip > dump_`date "+%Y-%m-%d"`.gz
更新:
在日期文件夹中备份数据库的所有集合。文件被 gzip 压缩:
mongodump --db somedb --gzip --out /backups/`date +"%Y-%m-%d"`
或者对于单个存档:
mongodump --db somedb --gzip --archive > dump_`date "+%Y-%m-%d"`.gz
或者当 mongodb 在 docker 中运行时:
docker exec <CONTAINER> sh -c 'exec mongodump --db somedb --gzip --archive' > dump_`date "+%Y-%m-%d"`.gz
使用mongodump
:
$ ./mongodump --host prod.example.com
connected to: prod.example.com
all dbs
DATABASE: log to dump/log
log.errors to dump/log/errors.bson
713 objects
log.analytics to dump/log/analytics.bson
234810 objects
DATABASE: blog to dump/blog
blog.posts to dump/log/blog.posts.bson
59 objects
DATABASE: admin to dump/admin
This command will make a dump of given database in json and bson format.
mongodump -d <database name> -o <target directory>
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 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
有一个名为:mongodump 的实用程序在 mongo 命令行上,您可以键入:
>./mongodump
以上将创建本地主机上所有数据库的转储。要转储单个集合,请使用:
./mongodump --db blog --collection posts
看看:mongodump
Edit: Updated commands based on latest version of MongoDB v4.4.2
to export
mongodump -d <database name> -o <backup-folder>
to import
mongorestore -d <database name> --dir <backup-folder>
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"
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.
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.
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
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 !!!!!
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
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
I created a library called BackSync which helps to backup and sync MongoDB databases (also local files/directories and some other known databases), you can also schedule it with pm2 to run the process automatically.
Install:
npm i -g @ayoubamine/backsync
Add your MongoDB backup source:
backsync add backup
Add your sync source (Local, Google Drive, ...):
backsync add sync
Then, run the process:
backsync run
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
