编辑:根据MongoDB v4.4.2最新版本更新的命令

出口

mongodump -d <database name> -o <backup-folder>

进口

mongorestore -d <database name> --dir <backup-folder>

使用mongodump:

$ ./mongodump --host prod.example.com
connected to: prod.example.com
all dbs
DATABASE: log    to   dump/log
        log.errors to dump/log/errors.bson
                713 objects
        log.analytics to dump/log/analytics.bson
                234810 objects
DATABASE: blog    to    dump/blog
        blog.posts to dump/log/blog.posts.bson

Mongo转储和恢复与uri到本地

mongodump --uri "mongodb://USERNAME:PASSWORD@IP_OR_URL:PORT/DB_NAME" --collection COLLECTION_NAME -o LOCAL_URL

省略——collection COLLECTION_NAME将转储整个DB。

在Windows中使用“path”，否则会给出错误:位置参数不允许

有一个实用程序叫做:mongodb 在mongo命令行中，你可以输入:

>./mongodump

上面的操作将创建本地主机上所有数据库的转储。要转储单个集合，使用:

./mongodump --db blog --collection posts

看看:mongodb

 Use -v to see progress of backup data
    mongodump -v --db dbname --out /pathforbackup/NewFolderforBackupData

 you can use it for restore also
    mongorestore -v --db dbname --drop /pathforbackup/NewFolderforBackupData/dbname

with multile v like -vvvv you will get more information
