New Macrium Reflect Updates [2]

What cereberus proposed would demonstrate the potential benefits of the premium feature Rapid Delta Restore. With Reflect Free the restore would replace all sectors with those from the image, whether the had changed or not. With RDR only those sectors that were different would be replaced.

The way cereberus asked you to set up this test would be an extreme example of this, probably completing the restore in less than a minute. The only sectors that would have changed since the image were those of the directory entries in the MFT that were pointing to the now deleted files, the sectors holding the data for the files themselves still being there, just marked as unused.

I don't think RDR does an undelete but physically restores files (or sectors) from image backup as somthing else could have overwritten the space in the meantime.

Pretty sure that was not what you meant, but just clarifying.

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
jimbo

My thought would be yes because it images and looks for changes at the sector level.

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.

I see. Thanks!

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.

Can you not go to disk management & initialise the 600GB of free space then format it?

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.
