MongoDB uses mongodump for data backup and restore

MongoDB Data Backup

In MongoDB we use the Mongodump command to back up MongoDB data. The command can export all data to the specified directory.

The Mongodump command allows you to specify the server to which the exported data can be dumped by parameter.

Grammar

The mongodump command script syntax is as follows:

>mongodump-h dbhost-d Dbname-o dbdirectory

• -h:
  

  MONGDB the server address, for example: 127.0.0.1, you can also specify the port number: 127.0.0.1:27017

• -d:
  

  The database instance that needs to be backed up, for example: Test

• -o:
  

  Backup data storage location, for example: C:\data\dump, of course, the directory needs to be established in advance, after the backup is completed, the system automatically establishes a test directory under the Dump directory, which holds the backup data of the database instance.

MongoDB Data Recovery

MongoDB uses the Mongorestore command to restore the backed up data.

Grammar

The mongorestore command script syntax is as follows:

>mongorestore-h 


 
 

  
  

 
 
 
 

  
  
 
   
--host <:p Ort>,-h <:p Ort>:
 
  
 
 
MongoDB server address, default is: localhost:27017

 
 

  
  
 
   
--db,-D:
 
  
 
 
A database instance that needs to be recovered, for example: test, and of course the name can be different from the backup time, such as Test2

 
 

  
  
 
   
--drop:
 
  
 
 
When recovering, delete the current data and then restore the backed up data. That is, after the recovery, add the modified data after the backup will be deleted, use with caution Oh!

 
 

  
  
 
   
<path>:
 
  
 
 
Mongorestore the last parameter, set the location of the backup data, for example: C:\data\dump\test.
You cannot specify both the <path> and--dir options,--dir can also set up a backup directory.

 
 

  
  
 
   
--dir:
 
  
 
 
Specify the directory to be backed up
You cannot specify both the <path> and--dir options.
