Secrets of Effective Backup: Focus on the Data Recovery Process

Secrets of Effective Backup: Focus on the Data Recovery Process

Along with the increasing threat of cyberattacks, backing up data is also increasingly crucial. For example, the website "Cyber Security for Society" explains that backup management is highly emphasized as a step to minimize the impact of security incidents.

Backups are indeed essential. However, one more thing should not be forgotten, which is the process of data recovery or restoring to its original state. Even if a backup has been done with great care, if the data cannot be recovered when needed, then the backup cannot be considered a fully effective security measure.

In this installment, we will discuss taking a "good backup" by emphasizing the importance of the restore process. In addition, we will explain why cloud backup can be a very effective tool for this purpose and provide some recommendations for cloud backup services worth considering.


 

Restore and Types of Backups to Understand

Restore is the process of returning data or systems to their original state. In the backup context, restore refers to returning a computer or server to its previous state based on the backup data created.

The restore process can take different amounts of time and effort depending on the type of backup used. Therefore, knowing the various types of backups is essential to understand the restore process truly.
 

There are three main types of backup

Full backup is the process of backing up all the data that is the target of the backup. Since all the data is copied each time, this process is time-consuming and requires much storage space. However, the advantage is that the restore process becomes faster and easier because all data is already available in one set.

Differential backup is a data backup that only includes changes or additions since the last full backup. The backup time is shorter than a full backup, and only the data from the first full backup and the last differential backup are required for the restore process.

Incremental backup is a data backup that only includes changes since the last backup, whether it was full or incremental before. This method is very efficient in terms of time and storage space. However, when performing a restore, the process becomes more complicated as it combines multiple data blocks from each backup stage.

In this discussion, we will focus on the importance of the restore process and share the secrets of creating good and effective backups. We will also explain why cloud backup is an effective solution and recommend the best cloud backup services to consider.


 

How to Recover Data from Backup

There are several ways to recover data from a backup. Performing regular backups and ensuring the recovery steps are well understood is essential to be ready when an emergency occurs.

The more straightforward the data recovery process from backup, the better. This is because, in an emergency, the ability to recover data quickly plays a vital role in maintaining business operations.

For example, the data recovery process is straightforward with our cloud backup service. Simply log in to the management screen via a PC and click the "Restore" button, and all previously backed-up data can be restored quickly and conveniently.



In addition, as will be explained further, the method used by a reliable cloud backup service is image backup, which backs up the entire system image in a single process. This method allows the recovery process to run quickly and efficiently.
 

Should you use cloud backup? Full Explanation and Features to Consider

In the past, a commonly used data backup method was a local backup, which stored backup data on other devices such as external hard disks or internal company servers. However, in recent years, more and more companies are turning to cloud backup due to its advantage in resilience against physical damage.

According to the Communications and Information White Paper (2023 edition) of the Japanese Ministry of Internal Affairs and Communications, by 2022, 72.2% of companies claim to be using cloud services at least partially. However, only 37.0% use these specifically for data backup. Compared to the 2021 figure of 34.6%, it can be seen that the use of cloud backup is slowly increasing.

In Indonesia, the adoption of cloud ology also continues to grow along with the increasing awareness of the importance of digital transformation. Many large and MSME companies are starting to utilize cloud services to support their operations and maintain data security. The government and private sector are also increasingly encouraging digitalization, including using cloud-based solutions to improve IT systems' efficiency, scalability, and resilience.

If your company is considering cloud backup, it's a good idea to understand its advantages and disadvantages to make the right decision.


 

Pros and Cons of Cloud Backup

Cloud backup has various advantages and disadvantages that need to be considered before implementation. The following is an explanation:
 

Advantage 1: Cost Savings

One of the main advantages of cloud backup is cost efficiency. Compared to local backups, cloud backups tend to be cheaper in terms of initial costs (installation costs) and operational costs.

For example, companies that choose local backups have to spend money to install and build servers in their offices. In contrast, with cloud backup, data is stored in the service provider's data center, so companies only need to choose a service plan according to their data capacity needs. The installation process is also much more straightforward.

In addition, local backups usually require dedicated IT staff who are always available in the office, adding to human resource costs. Management and maintenance can be completely handed over to a professional service provider in a cloud backup system, making it more cost and labor-efficient.
 

Advantage 2: Protection against Ransomware Attacks

In June 2024, there was a large-scale cyberattack on the file servers of the Dwango company, which is part of the KADOKAWA group. As a result of the ransomware attack, KADOKAWA announced on July 3 that there was a high probability of personal information leakage from Kadokawa Dwango Gakuen school.

This incident shows that large companies like KADOKAWA are being targeted, and small and medium-sized companies could potentially experience similar attacks. Ransomware can spread across devices within the same network or physically connected, so even local backups can become infected.

However, cloud backups store data in a location separate from the company's internal network, so the risk is much smaller. Cloud service providers are also usually cybersecurity experts, so data protection is more guaranteed in case something goes wrong.
 

Exhibit 3: Business Continuity Plan (BCP) Support

BCP (Business Continuity Plan) is a developed plan that allows the company to continue operating despite a disaster or other significant disruption.

In a local backup system, the risk of data loss is relatively high in the event of physical damage to the server. However, with cloud backup, data is stored in a location far from the headquarters, so the impact of a disaster can be minimized.

In addition, since cloud data can be accessed via the Internet, companies can still access and recover data from remote work environments. Thus, even if the office is damaged, business operations can continue.


  Then, what are the disadvantages of Cloud Backup,

Drawback 1: Internet Connection Required

One of the drawbacks of cloud backup is its dependence on an internet connection. The data backup process cannot be done if you are not connected to the internet.

Even if an internet connection is available, remember that backup performance depends on network speed. For example, when backing up large amounts of data, the process can take a long time. Similarly, the time taken can be pretty significant during the data recovery process.
 

Drawback 2: Unable to Build a Company-Specific Security System

Another drawback of cloud backup is that it is limited in meeting the company's specific security needs. In a cloud backup system, the service provider fully manages the security aspect. Therefore, for companies with particular internal security requirements, combining cloud backup and on-premise systems may be a more suitable solution.
 

More than Just Storage: Security to Patch Management in One

The advantage of cloud backup lies in its ability to store data and in how that data is protected. In emergencies such as cyberattacks or natural disasters, restoring backup data is essential to keep the business running.

For example, our cloud backup service, Cyber Protection, is equipped with Active Protection. This feature uses artificial intelligence (AI)-based technology to protect data from ransomware attacks. If suspicious changes are detected in stored files, backup data, or backup software, the system will automatically detect and stop the threat and restore the affected data.

When choosing a cloud backup service, selecting one with patch management features is highly recommended.

A patch is a repair file provided when a bug or security hole is found on a network or software. Patch management monitors patch deployment status across the network and periodically provides the necessary patches to maintain system security.

If patches are not applied immediately, this can become a security hole that can potentially be utilized by irresponsible parties to carry out attacks. Therefore, performing regular patch management is essential for maintaining network security.


 

Difference between Restore and Recovery

Here we will explain the term "recovery" often confused and equated with “restore”. Recovery is the process of returning the system as a whole to its normal state by performing several actions on the data that has been restored.

To understand the difference between restore and recovery, let's imagine a scenario where an individual user tries to recover an Excel file on his computer. The restore process means returning the Excel file to the computer. However, simply restoring the file does not necessarily make it immediately usable. A Microsoft Office application must be installed on the computer for the file to be opened. The process of installing these applications is part of recovery. So, the system is said to have recovered after all the supporting components are available and can function correctly.

As explained above, in the backup process, the important thing is to save the data and how quickly the system can be restored when a problem occurs. In this case, there is an excellent recovery method called instant recovery. With this method, virtual machine files can be read directly from the backup area without going through the usual recovery process so that the recovery time can be much faster. Because of this speed, instant recovery is an efficient solution as part of a Business Continuity Plan (BCP) strategy.


 

Difference between Restore and Recovery

Backup has become very important because the value of information assets owned by companies is increasing, while the threat of cyber-attacks has also increased significantly.

According to the National Cyber and Crypto Agency (BSSN) annual report, cyberattacks in Indonesia continue to increase from year to year. One of the most prominent types of attacks is ransomware, where the perpetrator encrypts essential data belonging to the victim and demands a ransom to recover it. In addition, attacks that exploit weaknesses in the supply chain are also a serious concern, especially for companies that rely on third-party systems in their operations.

A clear example occurred in 2022 when Bank Syariah Indonesia (BSI) experienced widespread service disruptions. While not officially confirmed as a ransomware attack, many suspected the incident involved an internal system compromise that impacted customer access and digital service continuity. Attacks like this show how important it is that backup systems are in place and secure from attacker access.

An Indonesian Cyber Security Research Institute survey and investigation found that although most companies claim a backup system, only a tiny percentage can recover data effectively during an attack. This shows that backups alone are insufficient if they are not supported by mature and tested restore systems and procedures.

If we just back up and feel satisfied, it's like buying emergency food for a disaster but never checking the expiration date. When disaster strikes, the food is no longer fit for consumption and cannot be used. The same applies to backup data-if it cannot be used during the recovery process, then its existence is useless.

With this in mind, when choosing a cloud-based backup service, it is essential to pay attention not only to the backup features but also how other features support the success of the recovery process. The key to a good backup is its ability to be used when needed.
