Delta restore is now available!!!!

[al3x]

I believe (only a guess here), since HBS uses no special changed block tracking driver, they are using the $MFT timestamp method for their DELTA operations.

Funny thing about this: HBS is faster in creating incremental images than Reflect, I can do incrementals in seconds and it's saving data at almost 4 GB/s in my test.
So if HBS really doesn't use any drivers for keeping track of changes, it probably should never do so. It just works

But let's wait for an official answer first
