Yo may find this description interesting _Rapid_Delta_Restore_(RDR) - Knowledgebase 8.0 - Macrium Reflect Knowledgebase
Hi folks
Actually this is more interesting than it might appear.
I have on a laptop an internal HDD which I've made into a single VHDX (Virtual phyiscal disk) where I have a number of Windows systems which are all single vhdx files -- e.g W11new.vhdx.
If I'm imaging the whole disk via this type of process is Macrium intelligent enough to know if anything on a particular vhdx file has changed !!. Remember from with a Windows system booted up on this method the "C" drive is still Windows but the actual physical vhdx disks is "Disk D" which is accessible and can be backed up from within any of the Windows systems booted from the vhdx.
I'll have an experiment with this -- make a very minor change on one of the windows systems and look at speed of backup and restore with Macrium 8.
Cheers

I think we are saying the same thing.
I was trying to say that when you delete a bunch of files after making the incremental image as you proposed, the sectors containing the file data do not change, only the sectors containing their directory entries. When you restore the image it is only those few sectors for the directories that have changed, so with RDR it should be blindingly fast.
Hmm - this is interesting. I keep my vhdx files on a separate drive (in a partition) and I just copy them to make a backup. It never occured to me that I could image backup drive with vhdx files, and use RDR to get back to original state.
The bit I am unsure is how an incremental backup backups a changed vhdx file.
Looks like I will be doing some testing.
Can Macrium restore an image from a 400GB drive to a larger 1TB drive? I need the destination to have 400 gigs of data and 600 gigs of free space. I must have did it wrong because I end up with 600GB of unallocated space.
You can allocate the unallocated space from Disk Management. What do you want to do with it? You can your MiniTool Partition Wizard to expand C: if you can't do it from Disk Management.
Post a screenshot from Disk Management if you need further help.
