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
                59 objects
DATABASE: admin    to    dump/admin

mongodb -h hostname -u dbusername -p dbpassword——db dbname——port portnumber——out /路径/文件夹

mongodb -h hostname -u dbusername -p dbpassword——db dbname——port portnumber——out /path/folder.gz

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。

或者你可以在Windows上做备份脚本，记得将Winrar添加到%PATH%

bin\mongodump --db=COL1 -o D:\BACK\COL1
rar.exe a -ep1 -r COL1.rar COL1
rename COL1.rar "COL1_%date:~10,4%_%date:~7,2%_%date:~4,2%_%time:~0,2%_%time:~3,2%.rar"

#rmdir /s /q COL1 -> don;t run this on your mongodb/ dir !!!!!

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>
