Data backups are a vital step to protecting data from cyber attacks. When recovering from malware or ransomware attacks, firms can use a saved backup to restore it to its previous state. However, to ensure total data security, any firm’s backup strategy should have multiple solutions in their overall strategy.
As per a report on Amount of data created, consumed, and stored,
A database can become unusable due to hardware or software failure, or both. Firms face storage problems, power interruptions, or application failures, but each failure scenario needs a different action.
As a result, data backups have become very important for firms. They help to greatly reduce the risk of losing data. In the event of a cyberattack or system failure, firms may be unable to access their data. Having a backup allows them to recover a copy of the data and make it accessible again.
What Is a Data Backup Strategy?
As per a Cost of Data Breach Report 2024 by IBM,
Data backup plans list out a clear roadmap for regular backups. They help in identifying where data is stored, storage policies, and back up methods. These factors are the basis of any data backup strategy.
It also assigns roles, explains how to recover data, and sets up testing rules. All these factors are helpful in making a structured plan for fast and efficient data recovery in critical situations.
What Are the Types of Data Backup?
The 3 key types of data backup are full, incremental, and differential.
Full Backups: Backing up all the data in a certain set of files or an entire system to a backup storage constitutes a full backup. This type of backup captures all the data. It does this without checking whether it has been changed since the last backup. Due to its thorough nature, full backups provide the most thorough protection.
Incremental Backups: Incremental backups are a quicker way to back up your data compared to full backups. They only copy the data that has changed or been created since the last backup. This could be a full back up or a previous incremental one.
Differential Backups: Differential backups, in contrast, record all the data that has been altered or created since the most recent full backup.

Data Backup Strategies for Firms
Firms usually follow more than one type of strategy in terms of backups. Some of them are as follows:
-
3-2-1 Backup Strategy
The 3-2-1 backup rule is a very effective guideline when planning a backup strategy. It means making three copies of the data, using two different storage types, and keeping one copy offsite. The copy is usually not kept in the same location as the other copies.
It’s a simple and reliable strategy that offers a well-rounded approach to backing up data.
-
Hybrid Backup Solutions
A hybrid backup solution is a refined approach to protecting data. It utilizes the joint benefits of both on-premises (local) and cloud-based backup strategies. By using the strengths of each method, it offers a versatile and strong data protection strategy.
One common hybrid setup combines on-site storage using a NAS (network-attached storage) device with cloud-based storage. The NAS holds data that the firm is likely to need, including in emergencies. Data from the NAS can also be backed up to the cloud for short, medium, and long-term storage.
-
Onsite Backups
Copies of data can be stored in physical locations within the premises. This could be a separate hard drive or a local device. This data backup strategy is known as onsite backups or local backups.
Having backups onsite gives firms quick access to their data. This is very critical for fast recovery during small issues or system failures. Keeping copies of the data on premise can help reduce downtime and make sure that operations aren’t interrupted.
-
Periodic Automated Backups
Periodic automatic backups are automated backups of the data as per a set schedule. These backups are defined by the regular output of identical copies at specific intervals. This helps ensure constant protection of data without the need for manual involvement.
This strategy works for many different types of firms. It can be adapted to meet detailed data protection and compliance needs.
-
Cloud Storage
Cloud storage for data is an excellent, widely used, and efficient method of protecting data. It requires storing data on remote servers managed by a third-party cloud service provider. This data can be accessed easily from any device with Internet.
This solution provides scalability, accessibility, data synchronization, and security. It also allows firms to outsource their data backup activities to an external partner.
-
Continuous Data Protection
Continuous Data Protection (CDP) is a data backup strategy that constantly captures and backs up changes to data as they happen.
A strategy like this is very important for mission-critical applications. It helps by reducing data loss and ensuring data accuracy is very important.
-
Backup Versioning
Backing up different versions of files and data over time is called backup versioning. This approach involves keeping track of changes made to files and data over time, so firms can go back to earlier versions if needed.
When set up correctly, this strategy can help firms make sure that their data is accurate and make it easier to recover lost data.
-
Offsite Backups
Storing duplicates of data in a different physical location from the primary data storage site are called offsite backups. This strategy offers additional protection by shielding the data from on-site disasters and risks.
Storing data in a remote location helps keep it safe and accessible, even in difficult situations. Whether firms use cloud services or other offsite storage options, keeping backups offsite is important. It helps in protecting data and planning better for emergencies.
Conclusion
Data backup strategies are important for firms of all sizes, not just a best practice for specific types of firms.
Neglecting it can lead to data loss, downtime, financial losses, legal issues, and reputational damage. Thus, to protect data and ensure continued success, investing in robust data backup and recovery solutions is important.
