Quick Start & Pro Tips
Configuring Advanced Backup Strategy
- Open O&O DiskImage and navigate to Settings.
- Select the Backup Strategy option from the menu.
- Choose your preferred strategy: Full backup, then create incremental backups, or Full backup, then create differential backups.
Why: Selecting the correct strategy optimizes storage space and recovery time. Incremental backups only save changes since the last backup. In contrast, differential backups save all changes since the last full backup.
Excluding Files from Backup Images
- Go to the Settings section of the application.
- Select Exclusion List from the configuration menu.
- Click the + button to add a new entry, entering the full path of the file or directory to exclude (directory paths must end with a backslash).
Why: Excluding non-essential or temporary files from the image reduces the overall backup size and speeds up the imaging process, saving valuable time and disk space.
Enabling Checksums for Unchanged Data
- Access the Program settings from the Start menu.
- Navigate to File operation > File backup options > Advanced.
- Ensure the option Use checksums to administer unchanged data is enabled.
Why: This advanced setting ensures that unchanged data is saved using checksums, which is necessary when using the Image of the changes method to ensure data integrity and proper administration of the image chain.
