If you’re new to backing up your data, the terminology can be confusing. You know you need to save your important files, but what’s the best way to do it? Two of the most common and powerful backup methods are “Mirror” and “Incremental.”
Understanding the difference is key to choosing the right strategy for protecting your photos, documents, and projects. Let’s break down these concepts with simple analogies and show how a free tool like RoboSuite makes it easy to get started.
The Incremental Backup: Adding to Your Collection
An incremental backup is the simplest and fastest way to keep a backup folder up-to-date.
- Simple Analogy: Think of it like adding new photos to a photo album. You don’t replace the entire album every time you take a new picture; you just add the new ones. An incremental backup does the same thing: it looks at your source folder and copies only the files that are new or have changed since the last backup.
- Pros:
- Fast: After the first full copy, subsequent backups are extremely quick because they only deal with new data.
- Safe: It never deletes anything from your backup destination.
- Cons:
- If you delete a file from your source, it will remain in the backup folder, which can lead to clutter over time.
This method is perfect for archiving and ensuring you have a copy of every file you’ve ever worked on.
The Mirror Backup: A Perfect Reflection
A mirror backup, as the name suggests, makes the destination folder an exact replica of the source folder.
- Simple Analogy: Think of it as a perfect mirror. If you add a book to a shelf (your source folder), the book appears on the reflection (your backup). If you remove a book from the shelf, it also disappears from the reflection.
- Pros:
- Clean and Synchronized: Your backup is always a perfect, up-to-the-minute clone of your source data, without old, deleted files.
- Space-Efficient: It doesn’t keep old versions of files you’ve deleted, saving disk space.
- Cons:
- “Danger” of Deletion: If you accidentally delete a file from the source, the mirror backup will also delete it from the destination on the next run.
This method is ideal for keeping a project folder perfectly synchronized between your PC and a NAS or external drive.
