Post subject:  Size of System C SSD vs Backup E SSD
First of all I'm running Win 10 Pro 64 bit V1809 that was freshly installed in March 2019 on a new Samsung EVO 970 Plus during my system hardware upgrade. This included a new ASRock Z370 Killer SLI/ac MoBo, Samsung EVO 970 Plus NVMe M.2 500 GB (System) & Samsung EVO 970 NVMe M.2 500 GB (Sys Backup), Intel Core i5 9600K CPU and Radeon RX 580 graphics.

My issue is the size of usage on my system drive C (Samsung EVO 970 Plus NVMe M.2) versus the bootable backup on drive E (EVO 970 NVMe M.2). As you can see in the pictures drive C is using 166 of 465 GB while drive E only uses 60 of 465 GB. Also, when I select all like shown in picture 2 and then show the properties for both drives C and E, their size in GBs is almost identical. I have Hidden Files visible to be able to select everything. So, where is the extra usage coming from on my drive C, over 100 GB worth of something? I just performed a disk clean-up and it didn't really do much. Something is eating up space and I'm having difficulty finding it. Thank you for your input.

What software are you using for your backup?

Casper version 10 for the bootable copy of System C

What puzzles me is that when all the folders are selected on their respective drives they total almost the same thing. The paging file on the system C drive is only 5 GB and it’s System Managed.

Don't forget that there are also things like system restore and previous versions taking space on your system drive.

I use Acronis True Image for backup images but not bootable, just mountable. My images are usually about 50 GB smaller than the used space on my system drive.

Very hard to diagnose this without being able to navigate through the file system personally. Is the backup compressed or a direct file copy? One observation is that the file count of the backup drive is over 3,000 less than your system drive and the folder count is also lower, by about 1,000.

@ Steve: I also noticed the file number difference which is what made me think that System Restore and/or Previous Versions might be involved.

I think that the backup is actually a clone process as it is stated that the backup is bootable. I just have no idea as if a clone backup would include such things as system Restore unless it were to be turned on for that specific backup drive. Yes, a clone should include System Restore but what if Restore were to be turned off for the backup drive. To be honest I just don't know...

The bootable backup hasn’t been been updated in a month. On the active System drive there are more windows updates and 12 restore points. That could account for the extra folders but 100 GBs more data...I’d be surprised. I won’t have time until Friday to dig into it more.

Hmmmm, haven't done a backup in a month...

Have you installed anything on the system drive? Windows Updates done and 12 restore points done since the last backup to the backup drive... I think that I could see a 100 GB difference as possible.

Except for the Windows updates there have been no new programs. That’s the reason for the long period of time from the last backup.

But the downloads for the Windows Updates can take a lot of drive space. These downloaded Updates take drive space to store. A normal Drive Cleanup will not get rid of these unless you do a followup selecting to clean up system files. Combined with other possible, already posted, possibilities the Update files could also easily be a factor in the drive size difference.

I updated to Windows 10 V1903 yesterday. I created an ISO file to make hard disk, a bootable DVD. This worked very well and this will be a repair disk as well. Anyway to the point, after updating to the new version all the extra GB weight (extra data) was removed. My system drive is using 74 GB. The backup without the paging and boot files active is using 53 GB. This is so much more where I want these drives to be.

Glad to read that the upgrade seems to have resolved the mystery space issue.
In line with your other post about the update, you may want to edit your sentence - "I created an ISO file to make hard disk." to read -- "I created an ISO file to make a bootable DVD."

Technically it is a hard disc as opposed to a USB flash drive I didn’t say hard drive (HDD). Yes it was bootable.

There is probably no Hibernation file included in the backup either so that would equal the amount of physical memory you have.

You are, of course, absolutely technically correct. :-D

Steve I did go back and edit the previous post to clarify so there wouldn't be any misunderstanding. ;) :D
