Backup Software That Only Copies Changes [Faster & Smarter]

Full backups copy everything every time, which takes a lot of time, storage space, and system resources. This results in data redundancy, especially when your data changes frequently. Thus, some users wonder if there is a type of backup software that only copies changes. Instead of backing up all files again, it saves only new or modified files, making the process much faster and more efficient.

Below, we’ll explain what it is, key features, recommended software, and how to use it. Scroll down to learn more!

What Does “Backup Software That Only Copies Changes” Mean?

Backup software that only copies changes refers to tools that avoid duplicating all data during every backup. Instead, they focus on saving only newly added or modified files. This is commonly known as incremental or differential backup, thereby addressing the shortcomings of full backups.

📌 Incremental backup copies only the data that has changed since the last backup (whether it was full or incremental). This means each backup is smaller and faster, making it ideal for frequent backups. However, restoring data may require multiple backup files in sequence.

📌 Differential backup, on the other hand, copies all changes made since the last full backup. While each differential backup grows larger over time, it simplifies recovery because you only need the full backup and the latest differential backup to restore data.

📌 Unlike incremental or differential backup, full backup copies every file every time, which can take hours when dealing with large disks or systems. Repeatedly storing the same data quickly fills up storage space, especially for daily backups, and also results in redundant data copies.

Top Features to Look for in Change-based Backup Software

When choosing backup software that only copies changes, the best solution is free and goes beyond simple file copying and provides incremental backup, schedule backup, fast recovery, etc., making the process simple and efficient.
