Azure SQL Backup, Azure VM Backup and Azure Backup Pricing in A New light

Last Updated

This article was last updated on August 5th, 2020.

In this article we will discuss all about the Azure VM Backup, Azure SQL Backup and Azure Backup pricing in an easy way but first we should know why Backups are important.


Why Backup?

Data is the currency of modern businesses but in today’s digital world, the amount of data organizations are creating and collecting is growing by over 40% per year. According to some analysis, 90% of the world’s current data was created in the last two years. This increase in data has yielded more ways in which to back it up. Ten years ago, data backup was simple. Copy files to a disk or backup to a tape. Today we have much more data, around 50 zettabytes. Research predicts that there will be 175 zettabytes of data on the planet by 2025. Those amazing effects lead to an ever-increasing cost to store and manage this data. Taking the regular backups of your data is much more important now a days than it used to be.

The primary explanation behind data backup is to save significant data if operating system crash's or hard drive failure happens. There ought to be extra backups if the original backup results in data corruption or hard drive failure. Extra backups are important in case of any man-made or natural disaster occurs.

Now Azure is taking care of all you backup problems. There is a core service that you want to take advantage of is Azure backup. Azure is providing Azure VM Backups, Application Level Backups, Azure SQL Backups and much more.


Azure Backups

Every byte in Azure is stored three times. So, do you really need to backup your data when you are already backing it three times? Yes, and yes. Azure does take three copies of your data and stores it in azure storage, but you still need azure backup to protect against ransomware, corruptions, or accidental deletion.

With Microsoft Azure backup you can eliminate expensive disks and tape costs, ensure that all your data is protected. It will enable you to either supplement your existing on-premises backup solutions or replace them entirely at a lower cost with a saleable, reliable, secure and encrypted cloud-based solution.


Features of Azure Backup


No More Tapes Needed for Backup

No need for tapes or any other capital cost to protect your data, therefore maintaining an expensive off-site storage facility becomes redundant. This help protect data against loss and corruptions.


Protect On-Premises and Azure VMs

Azure is providing you with the ability to protect your on-premises VMs running with windows or Linux but also your Azure VMs. That’s not all you can also do Azure SQL Backup or application level backups on Azure.


Long term retention

It enables you to keep your data for up to 99 years and meet any legal and compliance requirements. So, you might not be around in 99 years, but your backups will be.

The customers primarily use backups to retain their data for long term retention purposes and so azure backup is optimized based on the way that it compresses your data for long term retention. So, it gives you quick accessibility to your data but also keeps your costs low.


Consistent experience

Configuring, monitoring and recovering backups across local disks and cloud storage for on premises or cloud workloads.


Wide Application Support

Supports variety of applications such as SQL Servers, SharePoint servers, Exchange servers and even window client computers.


Security

Enjoy the confidence that your data is safe with Azure certified security privacy and compliance practices. Azure is certified with many times over with International Organization for Standardization.


Workload Protection Everywhere

Protect any cloud hosted, public or private running workloads.


Multi Factor Authentication

Azure backups are protected with multi factor authentication. So azure backups got you covered when it comes to security and protecting against ransomware.


Encryption

Azure Backups are encrypted while in transit or at rest.


Cost Effective

It’s a cost-effective solution metered by usage which transform your capital expenditure into a controlled and defined monthly operating expenditure.

Azure SQL Backup

There are three kind of Azure SQL Database, all are automatically backed up for minimum 7 days.


SQL Databases Types

  • Basic
  • Standard
  • Premium


Default Retention Period on Databases

The backup on these SQL databases are retained for different time period.

  • Data on basic retained for 7 days.
  • Data on Standard retained for 14 days.
  • Data on premium retained for 35 days.


Restore Options on SQL

With these backup option, SQL support two restore options

  • Point in time restore (permits a database to be reestablished to any point in time, up to the millisecond)
  • Geo-Restore (Uses a database's most recent geo-redundant backup to restore a database, it is used in case of regional outage)


Configuration Azure SQL long retention policies

You can also configure long term retention policies on Azure SQL Databases longer than the default retention period.


Azure SQL Backup

  • Login in portal.azure.com.
  • Select your SQL instance.
  • Click on Manage Backup.
  • Click on configure policies.
  • Select the Database of which you want to modify the backup retention policy.
  • Click on Configure retention.

  • Configure policy as required by your organization.


Azure VM Backup

You can create Azure VM Backup using azure portal. It is basically a GUI based portal, using this portal you can create, configure, modify and fetch the report from the portal. Azure Backup create recovery points which are stored into Geo-Redundant recovery vaults.

First you need to create a VM in azure and then after the creation of VM you can enable backup as per required by your organization. For critical data you are required to create hourly based backup policy, that is a best practice.

Following steps will guide you to schedule a daily backup on your VM.

  • Sign in into portal.azure.com
  • Click on Virtual Machine in the left side menu.
  • Select the newly created or existing VM.
  • Now, on the left menu find Operations section.
  • Click on Backup.
  • Select “Recovery Service Vault”, create new if you have no vault in your tenant. (A Recovery Services vault is a logical container that stores the backup data for each protected resource)
  • Select the Resource Group or create new.
  • Select the backup policy. By default, you will find a daily backup policy in that section. (You create and use policies to define when a backup job runs and how long the recovery points are stored. The default protection policy runs a backup job each day and retains recovery points for 30 days. You can use these default policy values to quickly protect your VM.)
  • Click Enable Backup to accept the daily backup policy.

By default, the vault is set for Geo-Redundant storage. To further protect your data, this storage redundancy level ensures that your backup data is replicated to a secondary Azure region that is hundreds of miles away from the primary region.

Size of Each Instance

Azure Backup Price/Month

Instance < or = 50 GB

$5 + storage consumed

Instance is > 50 but < or = 500 GB

$10 + storage consumed

Instance > 500 GB

$10 for each 500GB increment + storage consumed

Backup Storage Options

Multiple storage options - Azure Backup offers two types of replication to keep your storage/data highly available.

Locally redundant storage (LRS) replicates your data three times (it creates three copies of your data) in a storage scale unit in a datacenter. All copies of the data exist within the same region. LRS is a low-cost option for protecting your data from local hardware failures.

Geo-redundant storage (GRS) is the default and recommended replication option. GRS replicates your data to a secondary region (hundreds of miles away from the primary location of the source data). GRS costs more than LRS, but GRS provides a higher level of durability for your data, even if there's a regional outage.

Azure uses block blob storage for backing up. You need to choose between LRS or GRS, the pricing is different for both LRS and GRS


LRS

GRS

RA-GRS



Storage in GB/Month

$0.0224 Per GB

$0.0448 per GB

$0.0569 per GB

Examples

We got many questions from different customers how they will be charged for the Azure Backup, the below table will help you understand the pricing.

*Azure Resource cost is the resources you are using of azure i.e. Network, In-bound Outbound traffic etc.

**Actual cost may be high/low as compare to these written stats, depending on frequency of Azure Backups and Restorations.
