How difficult would it be to simultaneously defragment the destination drive as it is being restored? I wouldn't expect it to run as fast as a regular restore, but it would still be considerably faster then doing a restore or clone and defragmenting afterwards. It also would be an easy thing to set if doing an overnight or particularly large clone.

I would find this feature particularly useful when having to clone a person's drive from a full drive to a larger drive, because usually if a drive is full up it is also extremely fragmented (having no space to move files around).

Hi Reverent,

Technically, this is possible. In fact, if you are required to shrink a partition on restore (for example when restoring to a smaller disk), Reflect will automatically defragment the volume as part of the resize process.

However, this is as you have observed quite an time-consuming process - so to ensure disk images complete as quickly as possible we only perform this if we have to. In addition, we try to avoid modifying the underlying file system except where absolutely necessary to reduce the chance of inadvertently causing any issues - the idea being that you should get back exactly what you imaged.

We would recommend that customers who are looking to have a defragmented backup first defragment their volume before imaging it - Reflect will then take an image of the defragmented volume. Alternatively, you can defragment on restore.

In terms of the time cost, there would be no difference between the two - we have to undergo the same process as Windows does whilst defragmenting, so the time to restore with defragmentation would be the same as the time to restore plus the time to defragment.

This is something we may consider adding as an option to Reflect in the future, but at present have no plans for.

Kind Regards,

Macrium Support

Very well thought out response, and avoiding modifying the filing system as much as possible is a good philosophy to follow. Fair enough!
