如果你想使用mongoexport和mongoimport从数据库中导出/导入每个集合，我认为这个实用程序会对你有帮助。 我用过几次类似的效用;

对于本地和远程转储和恢复:

为当地

当地的转储

mongodump -d mydb -o ./mongo-backup

当地的恢复

mongorestore -d mydb ./mongo-backup/mydb

为远程

远程转储

mongodump --uri "mongodb+srv://Admin:MYPASS@appcluster.15lf4.mongodb.net/mytestdb" -o ./mongo-backup

远程恢复

mongorestore --uri "mongodb+srv://Admin:MYPASS@appcluster.15lf4.mongodb.net/mytestdb" ./mongo-backup/mytestdb

更新:

如果你正在使用mongo 4.0，你可能会遇到一个快照错误，那么你可以运行这个参数:——forceTableScan。更多信息请参见这里。错误是这样的:

mongodump error reading collection: BSON field 'FindCommandRequest.snapshot' is an unknown field.

如果你可以接受bson格式，那么你可以使用带有相同-d标志的mongodb实用程序。它将以bson格式将所有集合转储到转储目录(默认的，可以通过-o选项更改)。然后可以使用mongorestore实用程序导入这些文件。

#mongodump using sh script 
#!/bin/bash
TIMESTAMP=`date +%F-%H%M`
APP_NAME="folder_name"
BACKUPS_DIR="/xxxx/tst_file_bcup/$APP_NAME"
BACKUP_NAME="$APP_NAME-$TIMESTAMP"
/usr/bin/mongodump -h 127.0.0.1 -d <dbname> -o $BACKUPS_DIR/$APP_NAME/$BACKUP_NAME
tar -zcvf $BACKUPS_DIR/$BACKUP_NAME.tgz $BACKUPS_DIR/$APP_NAME/$BACKUP_NAME
rm -rf /home/wowza_analytics_bcup/wowza_analytics/wowza_analytics
### 7 days old backup delete automaticaly using given command

find /home/wowza_analytics_bcup/wowza_analytics/ -mindepth 1 -mtime +7 -delete

如果您想连接远程mongoDB服务器(如mongolab.com)，则应该传递连接凭据 如。

mongoexport -h id.mongolab.com:60599 -u username -p password -d mydb -c mycollection -o mybackup.json
