This is mostly for R&D team:
When imaging a whole drive or partition, some huge files like "pagefile" and such, may only make the backup huge for no good reason.
May be exclusion of specific files can be added as an option while creating a backup definition.
An idea to may be consider...

I believe the PageFile is already excluded...

That is indeed the case. Hiberfil.sys and swapfile.sys are also excluded. It may look like they are included when an image is mounted, but they are empty sparse files.

They will be excluded provided you're not using Rescue Media (when VSS is not used), otherwise backups running under Windows can use VSS and one of the VSS writers is tasked with slimming the backup.  So you also must NOT prevent that writer from running (e.g., retrying a backup without VSS Writers, which is an option setting).

Many thanks for the response :-)
What I suggested is for future builds to have (When creating backup definition/set of a whole drive or partition) an option to exclude files by choice/selection of the user.

File and Folder backup will let you choose which files to backup or to exclude from a backup. 

The image backup does NOT work with individual files.  It backs up clusters that are in use on a partition (or the whole partition). As noted above it is the VSS service that eliminates some of the large files when doing an image backup - not Reflect.

There's a registry modification method you can use to achieve this today, but Macirum notes that "it isn't 100% reliable", possibly because it relies on the VSS engine to perform the deletions as Drac noted above. But if you're interested: https://knowledgebase.macrium.com/display/KNOW80/How+to+exclude+files+from+a+Disk+Image

This is why I posted it in "my wish list" section.
I'm not referring to files and folders, but only to full drive/partition imaging.
In other backup apps, it is possible. I don't use them, but I do know them (Take Acronis True Image as an example).
In my view, it can be a useful improvement for future builds of "Reflect". :-)

Shai,

Using Acronis as an example when on this forum may not be a good plan.  Many of us are former Acronis users who left that product because it was almost always buggy, there was little or no interaction with the company, and they were slow to fix significant issues.  Some of those issues were caused by adding new features that were poorly implemented and tested.

We prefer a company that provides a reliable product, reacts quickly to issues and has access to developers in situations were a user has a problem with the product. 

I mentioned workarounds because I thought you might be looking for a way to accomplish the feature you requested using today's product.  After spending a lot of time providing significant speed improvements I would not expect Macrium to add something that might slow down the backup.  Storage is relatively cheap these days so one can get a 4 TB external drive for around $100.  If it is important to you to reduce file size, Files & Folder backup allows surgical precision.  If you want speed, image backup can do that.  I cannot speak for Macrium, but trying to do both may not be worth the time and money.  Of course that depends on how many people think that feature is important.
