This article will explain how to quickly clone partitions using Hasleo Disk Clone's Rapid Delta Clone feature, the main contents are as follows:
The traditional "Full Clone" method requires that all used data blocks be copied from the source drive to the target drive, whereas Delta Clone (also known as Incremental Clone) requires that only the changed blocks of the source partition relative to the target partition be cloned to the target partition, which means that an earlier “Full Clone” of the source partition must exist on the target drive.
Simply put, Delta Clone Technology is an efficient data synchronization method that significantly improves the efficiency of data backup and migration while reducing power consumption by only copying the data blocks that have changed since the last clone. The benefits of Delta Clone Technology include the following:
✦ 1. Efficiency improvement: The amount of data transferred is significantly reduced, depending on the number of changed blocks.
✦ 2. Reduced Power Consumption: The reduction in the amount of data transferred leads to a reduction in power consumption.
✦ 3. Time Saving: Compared to "Full Clone", only the changed blocks need to be read from the source drive and written to the target drive, so the time required for cloning is significantly reduced.
✦ 4. Reduced Costs: Some storages, such as SSDs, have a limited number of times they can be written, as a significant reduction in the amount of data written can lead to a reduction in hardware costs.
Below we will briefly describe the functional limitations and implementation principles of the Rapid Delta Clone feature in Hasleo Disk Clone.
✦ Limitation 1: Hasleo Disk Clone's Delta Clone feature currently only applies to cloning NTFS file systems, a full clone will be performed for other file systems.
✦ Limitation 2: The destination NTFS partition must be greater than or equal to the source NTFS partition.
✦ Limitation 3: The source NTFS partition and the target NTFS partition must have the same cluster size.
Hasleo Disk Clone checks to see if the NTFS partition on the destination drive is a clone of the NTFS partition on the source drive before performing the Delta Clone operation, then the program uses the advanced block change detection algorithm to find out the changed blocks that need to be cloned to the destination NTFS partition (e.g., blocks that have been changed on the destination NTFS partition and blocks that are already in use on the source NTFS partition but are not in use on the destination NTFS partition), and finally clones the changed blocks to the destination NTFS partition.
Step 1. Install and run Hasleo Disk Clone, click "Partition clone", and select the source partition for which you want to perform delta cloning, then click "Next".
Step 2. Select the destination partition you want to clone to and check the "Delta Clone" option, then click "Next".
Step 3. Hasleo Disk Clone starts delta cloning the changed data blocks from the source partition to the destination partition.
Step 4. Delta cloning completed. The time required to complete the delta cloning is related to the amount of changed data blocks on the source partition. In extreme cases, you can delta clone the source partition to the destination partition in a matter of seconds.
Have you been wowed? Yes, it's that fast. As a professional cloning software, Hasleo Disk Clone's Rapid Delta cloning feature can quickly clone only the changed blocks from the source partition to the target partition, ensuring that the target partition is an exact copy of the source partition.
