Types of Cloning
As the hard drive of your Mac machine contains many precious data in it, it is important to implement security measures against hard drive failure and other data loss instances. Cloning is the most effective data backup method that helps in keeping a second copy of data safe. With the cloning operation, you can create an exact clone of the source media, which allows continuing on-going important work, even if there is failure of the original media. There are various methods of drive cloning available, among which two methods are mostly used, such as File-level cloning and Block-level cloning.
Many expert Mac users, who know about the cloning mechanisms in detail even get confuse over these two drive cloning methods. Below descriptions will give them a clear picture about the two methods of cloning used in Mac cloning utilities:
File-level cloning -
In case of file-level cloning, the cloning utilities copy data from the source drive by one file after another, irrespective of the location of data on the media. File-level cloning first learns the logical file structure of the source drive and then builds the data structure of the new drive. With file-level cloning, the same directory structure and attributes (ownership, permissions etc.) are maintained in the destination drive.
Block-level cloning –
Block-level of cloning is performed by copying data from the destination hard drive to the cloned disk block wise. In case of block-level cloning, the cloning utilities bypass the general interpretation if logical file system and copy the layouts as well as the data content of the blocks in their original order. This cloning scheme also maintains the exact data, partition scheme, and format as the source drive.
However you can try Stellar Drive Clone software which can clone both file level as well as block level cloning. The software is read only and can clone your hard drive as well as volume.
