Mongodb Backup over nodeJS

Question

I have a mongoDB instance and using via my NodeJs/Express App. I have hosted it on Openshift. I am not able to figure out how to run a cron to backup the db.

I dont want to backup to s3.

Answer 1

尝试将包节点计划用于cron之类的过程。

Answer 2

Use node-schedule package to run your cron.

var schedule = require('node-schedule');

// Runs at 12am daily
schedule.scheduleJob('0 0 12 * *', function(){
    // Perform your database query to update your backup
});

OR Create a new DB (let's call it backup) and each time you update your actual DB, also insert into the backup DB.
