v6 with BETA CBT is even better than basic v6... easy to integrate and use. But remember, it's only better for multiple snapshots within a given System session. Once the System is reSTARTed, Reflect requires one image (any one taken the normal way) to set up the new CBT tracking reference... from there on it's very fast. Macrium did it this way because it found out that to try and determine whether a System had been "tweaked" since its last known operation was just too difficult and unreliable. Ax64 has always tried to do this and has had a miserable record of doing so. When it found that a System had been tweaked, it required a FULL System scan to generate the next snapshot... very time consuming. Reflect's method for doing this is excellent... no guesses.
