數(shù)據(jù)庫(kù)備份和數(shù)據(jù)恢復(fù)的重要性，我想大家都知道，這里就舉例說(shuō)明如何操作數(shù)據(jù)備份，數(shù)據(jù)恢復(fù)的實(shí)例：

創(chuàng)建測(cè)試數(shù)據(jù)

創(chuàng)建db:testdb,collection:user,插入10條記錄

mongo
MongoDB shell version: 3.0.2
connecting to: test
> use testdb
switched to db testdb
> db.user.insert({id:1,name:”用戶(hù)1″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:2,name:”用戶(hù)2″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:3,name:”用戶(hù)3″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:4,name:”用戶(hù)4″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:5,name:”用戶(hù)5″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:6,name:”用戶(hù)6″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:7,name:”用戶(hù)7″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:8,name:”用戶(hù)8″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:9,name:”用戶(hù)9″});
WriteResult({ “nInserted” : 1 })
> db.user.insert({id:10,name:”用戶(hù)10″});
WriteResult({ “nInserted” : 1 })
>
> db.user.find();
