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。

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

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

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 !!!!!

对特定db进行mongodb备份，使用bin sh命令删除7天前的备份

#!/bin/bash

MONGO_DATABASE="nexgtv_16"
APP_NAME="test"
MONGO_HOST="127.0.0.1"
MONGO_PORT="27017"
TIMESTAMP=`date +%F-%H%M`
MONGODUMP_PATH="/usr/bin/mongodump"
BACKUPS_DIR="/home/mongodbbackups/backups/$APP_NAME"
BACKUP_NAME="$APP_NAME-$TIMESTAMP"
$MONGODUMP_PATH -d $MONGO_DATABASE
mkdir -p $BACKUPS_DIR
mv dump $BACKUP_NAME
tar -zcvf $BACKUPS_DIR/$BACKUP_NAME.tgz $BACKUP_NAME
rm -rf $BACKUP_NAME
find /home/mongodbbackups/backups/test/ -mindepth 1 -mtime +7 -delete
