A tutorial on backing up and restoring MongoDB data in Windows or Linux systems _mongodb

MongoDB database backup and recovery under Windows

I can tell the data back to the C:\data\dump directory, first create this path. And then go under the Bin directory of MongoDB.

Mine is:

C:\Program Files\mongodb\bin

The backup script is:

Backup
mongodump-h 127.0.0.1:27017-d test-o c:\data\dump

The recovery script is:

Restore
 mongorestore-h 127.0.0.1:27017-d test--directoryperdb c:\data\dump\test

Explain the command you used.

• -h:mongodb server Address
• -D: database instance that needs to be recovered, for example: Test, of course, this name can also be different from the backup time, such as Test2
• -O: Backup data storage location, such as: C:\data\dump, of course, the directory needs to be established in advance, after the backup is completed, the system automatically set up a test directory in the Dump directory, which contains the database instance of the backup data.
• --directoryperdb: Where to back up your data, for example: C:\data\dump\test, why do you want to add a test instead of a backup dump, and read the prompts yourself?
• --drop: When you restore, delete the current data, and then restore the backed-up data. That is, after the recovery, after the backup to add modified data will be deleted, carefully use Oh!

Linux below MongoDB database backup and Recovery

Linux below we can create an automatic backup script, you can set a timed task, or you can manually back up. I backed it up manually.

First create an SH command, I put it underneath the home.

vim/home/mongobeifen.sh

Enter the following:

#!/bin/bash
shijie= ' date +%y%m%d%h '
backmongodbfile=mongodb$shijie.tar.gz
cd/home/mongodbback/
/usr/local/mongo/bin/mongodump-h 127.0.0.1--port 27017-u mongo-p 123456-d my_mongodb-o my_mongodb_dump/
tar czf $backmongodbFile my_mongodb_dump/
RM my_mongodb_dump-rf 

Explain:

The folder that holds the backup is/home/mongodbback/

-U is the database name user name-P is the password-D is the database name specific and window almost, you can look at the above Windows explanation.

When you back up, just run it.

./mongobeifen.sh  

It's OK.

Database recovery:

Point to each file

Copy Code code as follows:

/usr/local/mongo/bin/mongorestore-h 127.0.0.1--port 27017--Drop--directoryperdb My_mongodb_dump/my_mongodb

Point to a directory
If you have a problem, you can try the window's wording:

Copy Code code as follows:

/usr/local/mongo/bin/mongorestore-h 127.0.0.1:27017-d test--drop--directoryperdb My_mongodb_dump/my_mongodb
