Disaster Recovery vs Backup

Companies are always confused between normal backup and disaster recovery (DR). If you want to have a good disaster recovery strategy, then you need to invest some money into it. Disaster recovery and backups overlap in their objectives and methods. However, these practices have completely different aims. It is important to understand the difference between backup and disaster recovery. This will help you in creating an effective security strategy for your business.

In this article, we are going to talk about the key differences between disaster recovery and backups. Both of these practices will help you in protecting your business from unwanted downtime and data loss. We are going to examine both concepts in this article. This will help you in deploying the correct solution for your business.

Disaster Recovery vs Backup

Both data backups and disaster recovery will help you in protecting your business from data loss. There are two different practices that you can use for protecting your data:

  • Disaster Recovery (DR): Disaster Recovery is a plan which will help you in responding your business to a major incident. It will switch to an alternative IT infrastructure. Disaster recovery will ensure that your critical functions are running seamlessly. It will help you in protecting your business from human-made and natural disasters.
  • Backup: Backup is simply an extra copy of your data. You can store this data in another storage device like cloud storage, flash drive, and hard drive. If you have lost some important data, then you can recover your data from your backup files.

Backups are a very important part of your IT security strategy. It will help you in protecting your business from data loss. However, it is not a substitute for a disaster recovery plan. Data copies won’t help you in ensuring business continuity. If you want to ensure business continuity, then you will need a disaster recovery plan.

Definition of a Backup

A backup is a virtual or physical copy of your data. This will help you in restoring a file if your file gets deleted. Data backup is very important as it will help you in preventing data loss. You can lose data in these cases:

  • Natural disasters like earthquakes and fires.
  • Technical issues like failed software updates and database corruption.
  • Employee accidents like lost devices and accidental file deletion.
  • Data thefts like ransomware attacks and data breaches.

Organizations are generally creating data backups after every hour or day. This will ensure that they can easily recover their data. You should ensure that your backups are staying updated. It is a good idea to keep these data save points in various locations and media.

It is easy to set up a good backup process. Your IT security team needs to identify sensitive data and choose a backup type. They need to decide the duration of your backup. Ensure that you are complying with your storage requirements.

Different Types of Backups

The three main types of backups are:

  • Full backup: You will copy your entire data set in this type of backup. It is simple to set up and highly reliable. However, you need a lot of storage for storing the full backup. This will also eat a lot of network bandwidth.
  • Incremental backup: In this type of backup you will only update the files that have changed after the last backup. Incremental backup takes the least space and is the fastest backup type. You can perform this back up with very little network bandwidth. However, the restoration process will be time-consuming. It is impossible to recover your data if even one incremental backup is missing.
  • Differential backup: You will only backup the files that have changed after the last full backup. This will help you efficiently use your storage space. They are quicker when compared to full backups. However, it will use more space and network bandwidth when compared to incremental backup.

You can use multiple backup types for improving your business resilience. Every organization should follow the 3-2-1 backup rule. This simply means that you should have 3 copies of your data. 2 of these copies should be stored on-site and one copy will be stored in an off-site copy.

Definition of a Disaster Recovery

Disaster Recovery or DR is a set of procedures and policies which will help your company in quickly regain your IT systems during a disaster. The backup will only help you in creating restorable data points. DR is a complete strategy that will help you in ensuring business continuity. It will help you in ensuring that you can operate your business even during a disaster.

A DR plan will help you in switching to a redundant set of storage systems and servers. Your backup infrastructure will support the operations when your primary data center is down. Once your primary data center is up you can switch back to the primary data center.

If you don’t have a DR plan, then a disaster can have a huge impact on your organization. It will lead to permanent data loss. Due to this, you will lose revenue and sales. Also, your recovery costs will be very high. It will disrupt your supply chains. Your customer and employee satisfaction will go down. If you want to protect your business reputation, then you should ensure that you have a Disaster Recovery plan.
