Types of Backup: Full vs. Incremental vs. Differential Explained [When & How-To Guide]

All of your data can be lost at any time due to a system failure, data corruption, or irreversible deletion due to an error. 

The only way to deal with data loss is by implementing a reliable backup plan. Most businesses routinely backup their data; however, one-third have issues restoring data from backups. The conflict arises from how a "backup strategy" is viewed. At the same time, there is a related article about how to backup data you can learn it:

A backup strategy often begins and ends with what needs to be backed up. The rest concerns how to implement backups and what kind to use.

The best backup plan differs depending on the requirements of each firm. The three types of backup—full, incremental, and differential—and their benefits and drawbacks will be covered in this article to assist you in making the right decision for you and your company.

A big organization might opt for any backup like an incremental or differential backup approach, while a small business might decide to back up everything every day. Incremental backups are typically more suitable for cloud backup because they utilize fewer resources. Beginning with a full backup on the cloud, you may later switch to incremental backups.

What Is Backup?

According to Russ Fellows and Paul Crocetti from TechTarget, the term "backup" has come to mean data protection and can be carried out in several ways. Backup software solutions reduce the complexity of carrying out backup and recovery activities. Data backup is simply one component of a disaster protection strategy, and without thorough design and testing, it might not offer the desired level of data and disaster recovery capabilities.

Numerous different backup operations have long been available through backup software. The three types of backups most frequently used are full, incremental, and differential, and synthetic full backups and mirroring are other backup formats.

Data management is vitally important, and making backups of acquired data is essential. Backups shield information against human error, hardware malfunction, virus assaults, power outages, and natural disasters. If these errors occur, backups can help you save time and money. Different methods offer solutions to create backups, as follows:

1. 1. Backup software
2. 2. Manual backup
3. 3. Backup devices

Manually you can access the Control Panel. Then click System and Maintenance and press Backup and Restore. Select Set up backup, then follow the wizard's instructions if you've never used Windows Backup before or if you recently upgraded your version of Windows.

How Many Types of Backup - 3 Types: Full, Incremental, and Differential

• Full Backup
• Incremental Backup
• Differential Backup

Full Backup

According to Crocetti, a full backup is the most fundamental and comprehensive kind of backup process. As the name suggests, this backup copies all data to a disc or tape for storage. Every procedure should include a full backup to have a complete copy of all data on one media set. This is the main benefit. As a result, the time needed to restore data is kept to a minimum, or what is known as a recovery time objective. 

As a result, full backups usually are only performed occasionally. Small data centers (especially those with vital applications) may decide to execute a full backup every day or even more frequently in specific circumstances. In backup operations, a complete backup is commonly used in conjunction with incremental or differential backups.

Incremental Backup

As per Crocetti, only the data that has changed since the last backup operation of any kind will be copied due to an incremental backup procedure. An organization often uses the updated time stamp on files to compare it to the timestamp of the most recent backup. To track file changes since backup operations, backup software tracks and records the date and time that backup activities occur.

An organization may execute incremental backups as frequently as desired, storing only the most recent changes because they only replicate data that has changed since the last backup. The advantage of an incremental backup is that it replicates less data than a complete backup. As a result, these activities will quickly backup data and use less storage space.

Differential Backup

According to Crocetti, when a differential backup operation is run for the first time, it works similarly to an incremental backup in that it copies all the data that has changed since the last backup. But each time it is performed after that, it will keep copying all the data that has changed since the last complete backup. As a result, it will often save much less than a full backup but more data than an incremental backup on successive operations. Differential backups take longer and use more space than incremental backups, although they still take up less space than full backups.

Every backup method functions differently. A full backup must be performed at least once by an organization. You can do a further full backup, an incremental backup, or a differential backup for subsequent backups. The first partial backup, incremental or differential, will backup the identical information. By the third backup procedure, only the changes made since the previous total are included in the data backed up with an incremental. Comparatively, "Backup 1" was the initial full backup, while "Backup 3" with a differential will backup all alterations since "Backup 1".

Running a weekly full backup with daily incremental or differential backups is preferable for larger organizations or those with more data or server storage. For most circumstances, using differentials results in a higher data protection level with a minor storage space increase and faster recovery times. Because of this, we advise a strategy combining weekly full backups with daily differential backups is a wise choice for many businesses.

Full vs. Incremental vs. Differential, Which Backup Is Best?

Pros and Cons of Full Backup

Pros 

• Quick restoration
• Offers full copy of data set
• It offers arguably the best protection
• It uses a lot of bandwidth

Cons 

• Requires most storage
• It can be stolen if your backup is not encrypted

Pros and Cons of Incremental Backup

Pros 

• Less time consuming
• It takes the least amount of space
• It uses relatively little network bandwidth
• Availability of data

Cons 

• A full restoration cannot be performed if one incremental backup is missing or destroyed.
• Needs all the backups in the backup chain to restore

Pros and Cons of Differential Backup

Pros 

• It takes less space than full backups
• Faster restoration than incremental backups
• Shorter restore time

Cons 

• It uses much more network bandwidth than incremental backups but less than full backups.
• Requires large space

Therefore, incremental backups are generally better in the cloud because they often require fewer resources. Also smaller than differential backups are incremental backups. The smaller the backup, the better because storage space on the cloud is a significant cost component.

To Wrap Up

As there are 3 types of backup, and you can use any one, keep in mind the pros and cons mentioned above.

Use Full Backup if:

• You need the safest, most dependable way to copy data.
• Due to the constant availability of comprehensive data, restoration and recovery times are reduced. 
• It is simple to manage version control because all data is backed up simultaneously.

Use Incremental backup if:

• You need quick backup and an easier time restoring operations in emergencies. 
• You have low storage space needs and fewer network demands.

Use Differential backups if:

• You need to reduce storage requirements and restoration times. The backup will take less time to complete than a full backup because there are frequently fewer changes to data than the number of files in a data repository.

Whereas EaseUS Todo Backup is an easy and straightforward tool. For personal use, it provides more than enough capabilities. The system, disk/partition, and file backups can all be carried out by the application manually or automatically through scheduled backups. You can create incremental, differential, and full backups.
