Hasleo Backup Suite is comprehensive and cost-effective software that provides backup and restore functions, along with support for systems, disks/partitions, and files/folders cloning. This guide will introduce its advanced Delta Clone feature and explain how to use it to quickly clone a system to a new disk.
In data backup, cloning refers to creating an exact copy of the source data. Full Clone and Delta Clone are two different cloning methods. Full Clone refers to creating an exact, sector-by-sector copy of the entire source device (e.g., a disk or partition). This process clones all data from the source device, including the OS, applications, and settings, to the target device without modification. In contrast, Delta Clone synchronizes only the data that has changed since the last Full Clone to the target disk.
Each of the two modes has its advantages. Full Clone creates a complete copy of the source disk, ensuring data security, however, the cloning process is time-consuming. Delta Clone is much faster but must be based on an existing Full Clone and cannot function alone.
The following table compares Full Clone and Delta Clone to help better understand the differences between these two methods.
| Delta Clone | Full Clone | |
| Working Principle | Clone only changed data blocks | Clone all sectors or file-based data from the source disk |
| Disk Space Usage | Occupy less target disk space | Significant disk space usage |
| Clone Speed | Fast | Slow |
| Independence | Low (dependent on the last Full Clone) | High (fully independent copy) |
| Partition Structure Tolerance | Low (require identical partition structures on source and target disks) | High (allow modification of the target disk partition layout) |
| Data Status | Synchronize with the latest changes upon execution | Capture the complete state at execution time |
The purpose of Delta Clone is to clone only the data blocks that have changed relative to a historical benchmark point. Therefore, its most important technology for Delta Clone is rapid and efficient detection of these changed blocks. With an in-depth understanding of file system technology, Hasleo has developed advanced block change detection algorithms that can efficiently identify changed blocks, guaranteeing data consistency between the source and target disks while removing the resource waste caused by unnecessary data copying. In addition, it also has the following advantages:
Given these advantages, you can employ Delta Clone to regularly synchronize data disks, back up system disks, or create identically configured virtual machines for software/system testing. When using this powerful feature in Hasleo Backup Suite, please keep the following points in mind:
Step 1. Download, install, and run Hasleo Backup Suite. Click the "Clone" button in the navigation bar, then select "System clone" in the operation area.
Step 2. Hasleo Backup Suite automatically selects all partitions required for cloning Windows. Click "Next" to continue.
Step 3. Select the destination disk that contains the existing source Windows OS clone. Then, check the "Delta Clone" checkbox and click "Next".
* Tips: The Delta Clone operation will overwrite the corresponding sectors on the target disk. Please ensure that there are no other important files on the target disk.
Step 4. Hasleo Backup Suite starts the delta cloning process, copying only the changed data blocks from the source Windows to the destination. The operation time depends on the amount of changed data blocks on the source system disk. In extreme cases, it can finish in seconds.
The Delta Clone feature in Hasleo Backup Suite is powerful, allowing you to quickly clone your system to another disk. This significantly reduces cloning time and lowers energy consumption. As professional backup software, it also provides multiple backup modes (full, incremental, and differential), along with support for compressing, encrypting, merging and deleting backup images. With its comprehensive features and superior performance, Hasleo Backup Suite offers excellent value for money, making it the best choice for your data protection needs.
