Backup and Restore in mongoDB

Backup and Restore in MongoDB

Creating backups and restoring data using the utilities provided with MongoDB.

The mongodump and mongorestore utilities work with BSON data dumps and are useful for creating backups of small deployments.

Backup Can be created at any desired location.

Step For Backup- 

1. Run Command Prompt as Administrator.

2. Reach to Install location of MongoDB. (Ex C:\MongoDbNew\Server\bin)

3. Run this command

 C:\MongoDbNew\Server\bin\mongodump --host --port --username --password --db --out c:/backup

 -- host (Ip address of database server)

 --port (mongodb port 27017)

 --username (created user for database access )

 --password (Password to authentication)

 --db (database name backup to be taken)

 --out (location for backup)

 

Mongorestore can create a new database or add data to an existing database. However, Mongorestore performs inserts only and does not perform updates. That is, if restoring documents to an existing database and collection and existing documents have the same value _id field as the to-be-restored documents, Mongorestore will not overwrite those documents.

Step For Restore

1. Run Command Prompt as Administrator.

2. Reach to Install location of MMongoDB (Ex C:\MongoDbNew\Server\bin)

3. Run this command

C:\MongoDbNew\Server\bin\mongorestore --host --port --username --

password --db (back file location)c:/backup
