MongoDB Backup Options

In this video we are discussing MongoDB backup options

So there are multiple different options with the help of which the backup can be taken

We know that all the data are important and MongoDB is to store and hold huge amount

of data. To increase the availability, accessibility, we should have the backup of our data

So that in future if there is any kind of disasters are taking place from the backup, we can

restore our data. So, what are the different methods we are going to discuss here

So these, there are several backup methods are present and these are MMS, that is a MongoDB

management service. So this is one automated service. And next one is a copying files

So here in this case, we'll be doing the copy of our files, but later proper journaling

will be required for restoring them. And another one is a very famous option that is a Mongo dump So backup methods we are having this MMS Mongo management service copying data files and the last option we having this one

as Mongo dump. We shall be discussing all of them but one by one. So, at first we are going

to discuss MMS backup method. The MMS is the MongoDB management service and this service

supports the backup and restore functionality of MongoDB. This MMS is an automated feature

and it automatically creates a backup, the replica sets and starts systems from the MongoDB

cluster. So this is one automated feature which is available and coming with the MongoDB system

So it uses the restore options to get back and restore at any point from last 24 hours

So we can do the restoring from any point of the last 24 hours and that is our MMS backup method Next one is data file copying backup method So we can also create backup of the database contents by copying the files from the MongoDB system So we will be taking the copy

of the files from the MongoDB system but while restoring I require the proper journaling

So we need the correct journaling to restore files at the in the correct point

Next one is that we should stop all the writing processes into the MongoDB before performing the

copy operation. So, before performing the copying operation, all the right operations are to be suspended

So, if the snapshots are supported, we can use them to make backup at exact moment in time

So, that is our data file copying backup method. Let us go for the last option, that is the Mongo dump to backup

The Mongo dump creates high fidelity vision files and by reading the MongoDB database

So Bison means we are having the binary JSON So that is a binary JavaScript object notation It is known as Bisson So it is the MongoDB creates a high fidelity That means we can trust on that And this

Bison files by reading the MongoDB database. The Mongo dump and the Mongo restore. So two

commands are there. One is the Mongo dump and the one is the Mongo restore. And processes can

operate against the MongoD process and it can access underlying MongoDB files directly

So, Mongo dump means you are taking the backup and Mongo restore means from the backup

you are again restoring the MongoDB files. The Mongo dump does not capture the contents of the local databases

It deals with the global database only. So, Mongo dump can work also and then the MongoD server is not running

When the Mongo server is not running, then also the Mongo dump can work on the system

So here we have discussed the three different backup methods that is a MAM

MMS, copying files and Mongo dump. Thanks for watching this video
