Full Backup vs. Incremental Backup: Definition, Pros and Cons
Creating a backup of your computer can feel overwhelming, especially if you're new to the process. However, it's actually quite straightforward. You don't need to overcomplicate things - just take a few simple steps to ensure your important files and data are safely backed up.
If you're looking to choose the right backup for your needs, whether it's a full backup or incremental backup, we're here to help you make an informed decision.
When it comes to backing up your data, there are several options to choose from. The first type is a full backup, which involves copying all of your data to an external drive or cloud storage service.
What Is Full Backup
A full backup is a complete backup of your computer saved in a single file on an external drive, ensuring all files are protected in case of failure, data corruption, or data hijacking.
Regularly creating a full backup of a computer can be a time-consuming and resource-intensive process, making it a less desirable option for users and IT professionals.
A full backup is a good option for individuals or small businesses with limited storage space, as it completes quickly and takes up less space on the external drive.
What Is Incremental Backup
Incremental backup refers to creating a backup of data that has changed since the last backup, allowing for regular backups of changed data at a specified time.
To set up an incremental backup, you need to perform at least one full backup of your computer.
The system cannot provide a complete data record if an incremental backup is lost, because it only records changes made since the last backup.
Full Backup vs. Incremental Backup: Pros and Cons
Everything has its pros and cons, but ultimately, it comes down to what suits your specific needs, circumstances, and priorities.
Full backup and incremental backup are two popular options for users, but one may not be the best fit for your current needs and requirements.
To determine which backup type is best for you, let's weigh the pros and cons of full backups versus incremental backups. Full backups, which copy all data, offer the advantage of simplicity and ease of restoration, but can be time-consuming and require a lot of storage space.
Full Backup Pros & Cons
So here are the pros and cons of full backup:
Pros:
- Complete and quick data asset recovery.
- It's simpler to access recent backups and they're all in one place.
- Restoring your device is comparatively faster.
Cons:
- It needs lots of storage space.
- Backing up your data takes a long time.
Incremental Backup Pros & Cons
So here are the pros and cons of incremental backup:
Pros:
- It requires less storage space.
- It requires less bandwidth.
- Less time is needed to complete the backup.
Cons:
- The recovery process is slower.
- To set up an incremental backup, a full backup of the data is required first. This allows the incremental backup to reference the full backup and only record the changes made since then.
- Multiple backups are needed to piece together and perform recovery.
- If a version of a backup file goes missing, the missing version will not be recovered, but other versions of the file will still be available.
Full Backup vs. Incremental Backup (How to Choose)
A full backup is usually not the best option for users with large data drives, as it can take a long time to complete.
The larger the drive size, the slower the backup process will be. However, it's recommended to create a full backup every 3-4 weeks or at least once a month.
A full backup can be a great option for regular users and small business owners, as it allows for quicker recovery in case of data loss. This is because the recovery process is faster with full backup compared to other methods.
Incremental backup is a great option, where you create a full backup initially and then set up incremental backups to save changes made to files between the first backup and the present.
Incremental backup uses less storage space and allows for more frequent backups, but the recovery process is slow and a lost backup version is permanently lost.
A full backup captures all data, while an incremental backup only saves changes since the last backup. Full backups are better for initial setup or data loss, while incremental backups are more efficient for regular backups, as they only save what's changed.
| Full Backup | Incremental Backup | |
|---|---|---|
| Backup Speed | Slow | Fast |
| Storage Space Required | Large storage space is needed. | It doesn't take up much space. |
| Restoring Speed | Fastest | Slow |
| What files are backed up | All files | A full backup is required, and all files are incrementally backed up at a specified time after a full backup of the PC. |
| Duplicate files | Lots of duplicates are stored. | It doesn't save any duplicate files. |
Incremental backup is the most suitable option for users of any kind, including small business owners and individual PC users, because it requires a full backup to be created first, and then it can be used to create incremental backups, ultimately saving time and resources.

Final Verdict
You can create a full backup of your computer, and then create incremental backups to save storage space and time, as both types of backups complement each other.
When using incremental backups in your backup program, it's essential to also create a full backup of your computer periodically, rather than relying solely on incremental backups. This ensures that you have a complete and self-contained backup of your system, which can be restored in its entirety if needed, rather than relying on a series of incremental backups that may not be usable on their own.
When deciding between full backup and incremental backup, consider the trade-off between data recovery speed and storage space. Full backups, which copy all data, are ideal for critical systems and provide quick recovery, but consume more storage space.
