With the frequency of data breaches and outages increasing, having a solid data backup strategy is more important than ever. What should be included in the backup plan? How to make the backup plan? How to back up data? This post from MiniTool provides details.
Why Is Data Backup Important
Backups protect data from a variety of risks, including hardware failure, human error, cyber attacks, data corruption, and natural disasters. It's important to protect data from any potential issues so that organizations aren't caught off guard when something happens. The data backup will enable you to go back in time to the last known good point in time before the problem occurred.
How to Create the Backup Plan
Now, we will introduce how to create the backup plan. Follow the steps below.
Step 1: Assess Your Backup Needs
Step 1 for the data backup plan is to assess your backup needs.
You need to understand the structure and type of data you are dealing with and determine what should be included in the backup plan.
To reduce the risk of data loss, you need to back up your files and databases and you also need to back up your operating system, applications, configuration. If you use virtualization, you need to back up your hosts and management consoles and your virtual machines (VMs). If you use cloud infrastructure as a service (IaaS), you need to include it in your scope.
When classifying your customer's dataset, you may also need to consider the following data categories:
- System data: This includes operating system data, which, as it turns out, does not change frequently during the backup lifecycle.
- Application configuration data: This refers to the software configuration files that make up the building blocks of the application. Therefore, application configuration data should take precedence over the application itself.
- Operational data: These are files that are constantly changing, such as user documents, mailboxes, and databases. Since they are both critical to your customer's business operations, you should keep them separate from other backups while maintaining high availability.
You can also categorize data based on its urgency for recovery.
- Hot data: Refers to critical business documents frequently accessed by your customers. Therefore, your data backup plan should update them regularly while ensuring high availability.
- Cold data: Unlike hot data, cold data is rarely accessed because it is not that important. You can regard it as secondary data that you can back up to a separate, less available location.
- Archived data: Although archived data is rarely accessed, it is often retained for long periods for audit or compliance purposes. Therefore, you can compress and then create backups that remain unchanged for many years.

Step 2: Understand the Types of Vulnerabilities
Step 2 for the backup planning is to understand the types of vulnerabilities.
After defining the dataset, you should conduct a full security audit and you need to understand the types of vulnerabilities your system is facing. The following are the types:
Malware risk: Hackers are increasingly creating sophisticated malware that can penetrate moderately secure networks. Such attacks are carried out through ransomware, Trojan horses, and various economically motivated worms.
Hardware failure: This type of failure is very common, even in the most advanced IT infrastructure. They range from system crashes and power outages to power failures, communication failures, and hard drive crashes.
Natural disasters: While natural disasters are not as common as malware, they are extremely harmful. Events such as hurricanes, landslides, tsunamis, earthquakes, and wildfires have the potential to destroy data storage devices.
End-User errors: Hackers especially like to exploit end-user errors to infiltrate networks and gain access to sensitive data. Because of it, you may want to strictly control data access in the backup plan.
Step 3: Choose the Backup Solution/Destination/Scheme
Step 3 for creating the backup plan is to choose the backup solution, device, and scheme.
1. Backup Solution
The data backup market is large and growing. Therefore, there are a variety of backup storage solutions. The three main options are - hardware appliances, software solutions, and cloud services.
These devices usually include storage, which is a device that you can install and connect to your network. These devices are easy to install and configure. In most cases, you do not need to configure a separate server, operating system, or install any software. An agent installed on your system performs the backup, and you can access the solution through the graphical interface provided by the appliance.
However, keep in mind that if your hardware device fails, you will lose your entire data backup solution. Even if you back up to a secondary location, you will need to reconfigure your backup solution before restoring, which increases your restore time.
The software solution installs on your own system and handles the backup process. Many solutions allow you to use existing systems, but some require dedicated servers configured specifically for backup. For these, you need to install and configure the operating system and backup software. In many cases, you can install software on a virtual machine (VM).
Software solutions offer greater flexibility than hardware appliances, especially if your infrastructure changes frequently. Also, software solutions can be cheaper than buying a hardware appliance package, and they also allow you to choose and configure your own storage.
Many vendors offer Backup as a Service (BaaS)—a cloud-based offering that allows you to configure and run backups from a vendor or service provider's cloud infrastructure by installing a lightweight agent on your machine. BaaS is even simpler than software because there is no need to configure the operating system.
Of course, if your organization handles sensitive data or is subject to regulatory requirements, you will need to check whether cloud backup using a BaaS solution is acceptable.

2. Backup Devices
You should also choose the backup devices for the backup plan. There are four main devices - local or USB disks, NAS, tape, and cloud storage. To get more information, you can refer to this post - Computer Backup Devices & How to Back up Data to Them.
3. Backup Schemes
There are many types of backups, and you should choose according to your backup plan. Here are three main backup schemes:
Full backup - copies the entire system.
Incremental backup - copies all files that have changed since the last backup.
Differential backup - copies all files that have changed since the last full backup.

Step 4: Test the Recovery
Step 4 for creating the backup plan is to test the recovery.
Before you fully deploy a backup, you had better use it for testing. Your data backup plan should include a comprehensive testing program to confirm that everything is running smoothly. And, most importantly, you should run data recovery tests to evaluate your recovery speed and disaster recovery capabilities.
You should remember to test all types of backups and confirm that they are recoverable. Since different types of backups have different structures, they present various data recovery challenges.
Hence, you need to pay attention to RPO (Recovery Point Objective) and Recovery Time Objective (RTO). RTO specifies the time required to recover all system resources after a disaster. RPO helps you establish optimal data backup frequency by calculating and defining the maximum tolerable data loss.
