No “Clone Wars” at Macrium!

RDCAs with Rapid Delta Restore (RDR) the concept of Rapid Delta Clone (RDC) has been something that has been thought about for quite some time here at Macrium Software. We wanted to build a clone solution that would effectively and rapidly copy only the differences between the source and target file systems. The advantage of this is obvious, RDC offers similar a performance increase as an Incremental disk image offers over a Full image and enables regular clones to become a viable and fast DR solution.

How does it work?

The NTFS file system resident on the clone source is compared with file system on the target disk. The two file systems are first verified that they originated from the same format command and then the target NTFS file system structures are analysed for differences. All the NTFS file system structures are copied to the target disk and any that do not exist or have been modified on the target disk trigger the data records for each NTFS file or object to be copied as well. The result is an ‘Incremental’ clone applying only file system changes detected between the source and the target.

Rapid Delta Clone is a feature of Macrium Reflect v6.
