Cumulative Incremental Backup

Definition of Cumulative Incremental Backup

Cumulative Incremental Backup refers to the process of backing up only the data that has changed since the last incremental backup. This backup method saves storage space and time compared to a full backup. However, it requires more time to restore data in case of loss, as it needs both the last full backup and all subsequent incremental backups.


The phonetic pronunciation of “Cumulative Incremental Backup” is:k(y)oo-MYOO-luh-tiv in-KRE-men-tuhl BAK-uhp

Key Takeaways

  1. Cumulative Incremental Backup only stores the changes made since the last Full Backup, which reduces the storage space needed and shortens backup time compared to Full Backups.
  2. Restoring data from a Cumulative Incremental Backup requires both the last Full Backup and the most recent Cumulative Incremental Backup, making the restoration process quicker than with Differential Backups.
  3. While more efficient than Full and Differential Backups in certain aspects, Cumulative Incremental Backups can cause redundancy, as some files may be backed up multiple times if they’re consistently modified between Full Backups.

Importance of Cumulative Incremental Backup

Cumulative Incremental Backup is an important technology term because it refers to a highly efficient method of data protection, critical for organizations and individuals alike.

This backup strategy involves saving only the changes made to data since the last incremental backup, significantly reducing the time, storage and bandwidth requirements when compared to full backup methods.

By storing these modified data chunks, it allows for faster restoration while decreasing resource consumption, providing a reliable safeguard against data loss.

Additionally, cumulative incremental backups contribute to the optimization of information management and help in developing a strong disaster recovery plan, ensuring business continuity and enhanced security in the modern digital landscape.


Cumulative incremental backups serve a vital purpose in data protection and recovery strategies by offering a balanced solution between full and differential backups. The overarching aim of cumulative incremental backups is to minimize the time and storage space required for safeguarding and restoring essential data.

By copying only the files that have changed since the last full backup, cumulative incremental backups are more efficient than full backups, as they don’t consume as much time, storage space, and resources. Users can tailor their backup to their preferred frequency, be it daily, weekly, or monthly, to enhance their system’s security and keep data current.

Moreover, the cumulative incremental backup system significantly streamlines the data restoration process. In the event of data loss or hardware failure, the system only requires a full backup and the latest cumulative incremental backup to fully restore the saved data.

This is unlike with traditional incremental backups, which would need a full backup along with a chain of incremental backups. With a cumulative incremental backup, administrators can avoid the hassle of managing multiple incremental backups and focus on a simplified backup schedule, which ultimately reduces the chances of missing or mishandling critical data, resulting in a more robust and cost-effective data protection strategy.

Examples of Cumulative Incremental Backup

Cumulative Incremental Backup is a data backup strategy that involves backing up all files and data that have changed since the last full backup. This technique helps reduce the time, storage, and resources required for backing up data compared to performing a full backup every time. Here are three real-world examples of using Cumulative Incremental Backup technology:

Business Data Protection: A medium-sized company maintains a database with a large amount of customer and sales information. Performing a full backup daily is time-consuming and not efficient. Instead, the company uses a cumulative incremental backup solution. They perform a full backup once a week and then use the incremental backup system to backup any new or modified data daily. This system saves storage space and allows for quicker recovery in case of data loss.

Personal Computers: Individuals who want to ensure that their personal files, including photos, music, documents, and more, are safely backed up can use cumulative incremental backup technology. By doing an initial full backup and then performing regular, smaller backups of newly added or changed files, the user can save time and minimize the risk of losing valuable data.

Educational Institutions: Schools and universities have a significant amount of critical information, such as student records, grades, and course materials. To ensure data protection, these institutions can use a cumulative incremental backup system. This would involve performing a full backup at the beginning of each semester and implementing incremental backups throughout the semester to capture new or updated data. This method minimizes backup time and the resources needed while ensuring that essential information is available if a data loss situation occurs.

Cumulative Incremental Backup FAQ

1. What is a cumulative incremental backup?

A cumulative incremental backup is a type of backup that only saves the changes made since the last full backup, rather than saving all the changes since the most recent incremental backup. This results in faster backup times compared to a differential backup and requires less storage space.

2. How does a cumulative incremental backup differ from a full backup and a differential backup?

A full backup is when a complete copy of all the data is made and stored. A differential backup saves only the changes made since the last full backup, and a cumulative incremental backup saves only the changes made since the most recent full backup. The differential backup takes longer to complete and needs more storage space compared to a cumulative incremental backup.

3. Why should I consider using cumulative incremental backups?

Using cumulative incremental backups provides several advantages, such as shorter backup times, reduced storage requirements, and faster recovery times compared to differential backups. This makes them an optimal choice for organizations needing frequent backups with less impact on system resources.

4. How do I perform a cumulative incremental backup?

To perform a cumulative incremental backup, you will need backup software that supports this feature. First, create a full backup of the data you wish to protect. Then, schedule a regular cumulative incremental backup to ensure that any changes since the last full backup are captured and saved.

5. How do I restore data from a cumulative incremental backup?

In case of data loss or corruption, to restore your data from a cumulative incremental backup, you will need the most recent full backup and all subsequent cumulative incremental backups. The restoration process involves applying the full backup first and then applying each cumulative incremental backup in sequential order until the most recent backup is applied.
