Flint Backup

Flint Backup

Flint Backup is a Windows backup utility that lets you back up files and folders to a specified destination using mirror backup, standard copy, or ZIP compression.

You can create multiple backup slots and run them sequentially. Frequently used slot configurations can be saved as up to 8 separate presets and switched between as needed.

How to Use

1. Select the folder or file you want to back up in each slot.
2. Choose the destination where the backup will be stored.
3. Select a backup mode: Mirror, Standard, or ZIP.
4. Add more slots if needed, or select Exclude from Current Run to skip a slot.
5. Click Start Backup.
6. Monitor the current progress, files copied, files reused, and overall progress at the bottom of the window.

Backup Modes

• Mirror: Maintains the same directory structure as the source, updates only changed files, and removes items from the backup that no longer exist in the source. Unchanged files are reused whenever possible instead of being copied again.
• Standard: Copies source files and folders to the selected destination.
• ZIP: Compresses the source files and folders into a ZIP archive.

When performing mirror backups from virtual drives such as Google Drive, Flint Backup first compares file sizes and modification times. If only the modification time differs, it checks the actual file contents to avoid unnecessarily copying identical files.
