MongoDB Backup and Recovery

Backup

-d Specifies the database to be backed up,-o Specifies the backup location,

bin>mongodump-d test-o Backup//(backup is the back up directory, created to the bin directory by default)

Recovery

-d Specifies the database to revert to, which restores the backed-up database to a database that does not have the same name as the original, where mongodb2,--drop means to delete the collection (if any) before recovery. Otherwise, the data is merged with the existing collection data and may overwrite some documents.

bin>mongorestore-d Test--drop backup/test/

Inserting test data

> Db.test.save ({123: ' abc '})

> Db.test.find ();

#查看所有数据库

#查看主从复制状态

#修复数据库

Db.repairdatabase ()
