Summary
Incremental backups are a key component in data management, focusing on storing only the files that have changed since the last backup, whether it be full, differential, or incremental. This method is more efficient and faster compared to full backups as it only captures recent changes. The article explores the concept of incremental backups, compares them with other backup types, and discusses their benefits and drawbacks, providing a comprehensive understanding of their functionality and appropriate usage scenarios.

What is an Incremental Backup?

An incremental backup is a backup type that only stores files that have changed since the last full, differential, or incremental backup. This method is significantly faster than performing full backups repeatedly because it only captures the changes made since the most recent backup. The name “incremental” comes from the fact that each backup is an increment of the previous one.

How it Works

To illustrate, let’s consider a scenario:
- Day 1: A full backup is performed, capturing all data.
- Day 2: An incremental backup is taken, capturing only the changes made since Day 1.
- Day 3: Another incremental backup is taken, capturing changes made since Day 2.
While incremental backups are efficient for regular backups, restoring data can be more complex. To restore data, you need the last full backup and all subsequent incremental backups.

Types of Incremental Backups

There are several approaches to incremental backups, each with its unique characteristics:
1. Block Level Backup: This type backs up only the modified parts of a file, making it ideal for large files with minimal changes.
2. Byte Level Backup: Similar to block level, but it operates on binary variations of the file compared to the previous backup.
3. Reverse Incremental: Produces a backup chain with the most recent restore point always being a full backup, updated after each backup job.
4. Multilevel Incremental: Involves multiple numbered backup levels, with each level backing up changes since the most recent lower-level backup.
5. Incremental Forever: Similar to synthetic backups, where only incremental backups are sent to a centralized system, which keeps track of all increments.

Advantages and Disadvantages

Advantages

  • Fastest Backup Type: Since it only backs up increments, it is quicker than other methods.
  • Storage Efficiency: Saves storage space by only storing changes.
  • Version Control: Each increment can store a different version of a file or folder.

Disadvantages

  • Slower Restore: Restoring data is slower because it requires the first full backup and all subsequent increments.
  • Complex Restore Process: Finding the increment that contains the latest version of a file can be time-consuming.

Step 2: Select the source file and the destination. The source file typically defaults to the system partition, and the destination is where you want to save the system backup. In the backup plan, choose a suitable scheme based on your needs. Renee Becca offers 5 options: version chain mode, single version mode, full mode, incremental mode, and differential mode.
system backup mode
Renee Becca offers 5 backup plans:
* Version chain mode: Keeps the latest 5 versions, automatically deleting older versions after each backup.
* Single version mode: Retains only the most recent version, deleting the previous one after each backup.
* Full pattern: Creates a full backup.
* Incremental mode: After an initial full backup, only incremental backups are created.
* Differential mode: After an initial full backup, only differential backups are created.
In addition, using Scheduler, you can set a daily/weekly/monthly automatic backup plan and the time to start the backup. Click (OK) to enable the automatic backup.

Step 3: After all settings are completed, click (Backup). You can view the backup progress by switching to the Task tab on the main interface of Renee Becca. If you need to restore the system, please read the System Restore guide.

Conclusion

Incremental backups are a powerful tool for efficient data management, offering quick backup times and storage savings. However, they come with the trade-off of potentially slower restores. Understanding the different types of incremental backups and their advantages and disadvantages can help you choose the best backup strategy for your needs. Whether you opt for incremental, differential, or full backups, each method has its place in a comprehensive data protection plan.
