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

 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

下面的命令将工作，采取mongo db转储。

mongodb -d -o

在Windows上:试试这个，其中c:\ mongodb是转储文件的位置， 它将创建json格式的元数据，并以bson格式进行备份

C:\MongoDB\bin> MongoDB -d -o

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

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

cmd - - - >

C:\Program Files\MongoDB\Server\3.2\bin>mongodump.exe --db Dintest
