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

要转储数据库进行备份，可以在终端上调用此命令

mongodump --db database_name --collection collection_name

要将备份文件导入mongodb，可以在终端上使用以下命令

mongorestore --db database_name path_to_bson_file

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>
