1. Backup MongoDB Database<\/strong><\/h2>\n\n\n\n

\u2705 Option 1: Backup Entire Database<\/h3>\n\n\n\n

Use the mongodump<\/code> command.<\/p>\n\n\n\n

Syntax:<\/strong><\/p>\n\n\n\n

mongodump --db <database_name> --out <backup_directory>\n<\/code><\/pre>\n\n\n\n
Example:<\/strong><\/p>\n\n\n\n
C:\\backup>set path=C:\\Program Files\\MongoDB\\Server\\8.2\\bin\nC:\\backup>mongodump --db emp1 --out c:\\backup\n\nmongodump --db testdb --out C:\\backup\\\n<\/code><\/pre>\n\n\n\n
This will create:<\/p>\n\n\n\n
C:\\backup\\testdb\\\n<\/code><\/pre>\n\n\n\n
Containing .bson<\/code> (data) and .metadata.json<\/code> (indexes).<\/p>\n\n\n\n
\n\n\n\n
\u2705 Option 2: Backup All Databases<\/h3>\n\n\n\n
mongodump --out C:\\backup\\all_dbs\\\nC:\\backup>mongodump --out c:\\backup\\alldbs<\/code><\/pre>\n\n\n\n
\n\n\n\n
\u2705 Option 3: Backup with Authentication<\/h3>\n\n\n\n
If your MongoDB has authentication enabled:<\/p>\n\n\n\n
mongodump --uri=\"mongodb:\/\/username:password@localhost:27017\/testdb\" --out C:\\backup\\\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
2. Restore MongoDB Database<\/strong><\/h2>\n\n\n\n
Use the mongorestore<\/code> command.<\/p>\n\n\n\n
Syntax:<\/strong><\/p>\n\n\n\n
mongorestore --db <database_name> <backup_folder_path>\n<\/code><\/pre>\n\n\n\n
Example:<\/strong><\/p>\n\n\n\n
mongorestore --db testdb C:\\backup\\testdb\\\n<\/code><\/pre>\n\n\n\n
This restores the testdb<\/code> database from the backup folder.<\/p>\n\n\n\n
\n\n\n\n
\u2705 Option 2: Restore All Databases<\/h3>\n\n\n\n
mongorestore C:\\backup\\all_dbs\\\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
\u2705 Option 3: Restore with Authentication<\/h3>\n\n\n\n
mongorestore --uri=\"mongodb:\/\/username:password@localhost:27017\" C:\\backup\\\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
 Useful Flags:<\/h3>\n\n\n\n
Option<\/th>Description<\/th><\/tr><\/thead>
--drop<\/code><\/td>Drops existing collections before restoring.<\/td><\/tr>
--gzip<\/code><\/td>Use if your backup was compressed.<\/td><\/tr>
--verbose<\/code><\/td>Displays detailed output during restore.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
Example with --drop<\/code>:<\/strong><\/p>\n\n\n\n
mongorestore --drop --db testdb C:\\backup\\testdb\\\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
 Example Backup & Restore Workflow<\/h2>\n\n\n\n
Step 1:<\/strong> Backup<\/h3>\n\n\n\n
mongodump --db studentDB --out C:\\mongo_backup\\\n<\/code><\/pre>\n\n\n\n
Step 2:<\/strong> Delete or modify data (simulate loss)<\/h3>\n\n\n\n
use studentDB\ndb.students.drop()\n<\/code><\/pre>\n\n\n\n
Step 3:<\/strong> Restore<\/h3>\n\n\n\n
mongorestore --db studentDB C:\\mongo_backup\\studentDB\\\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
 Backup & Restore Files Created<\/h2>\n\n\n\n
Each collection is saved as:<\/p>\n\n\n\n
    \n
  • collection_name.bson<\/code> \u2014 raw data<\/li>\n\n\n\n
  • collection_name.metadata.json<\/code> \u2014 index and metadata<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
