Windows 10: The backup failed. There was a failure while compacting virtual disk on backup location...

I was doing a system image backup on USB flash drive which almost 2 TB, I was doing backup to network location, like the video on he instruction:

It is basically explains how to do image system backup to USB flash disk.


I checked the files on USB disk, it seems it did backup a system image, but, I got this error anyway.


Can someone let me know what is going on?


Thanks in advance.

Windows 10 Pro Error codes returned after failing making a second System Image Backup

After creating a successful image backup on my second hard drive, I placed that backup into an
identifiable folder. Then I perform some system changes and start an image bakup again however it will now fail with the following error messages/codes:

- There was a failure compacting the virtual hard disk on the backup location. (0x80780151).

-Additional Information:

The process cannot access the file because its being used by another process. (0x80070020).

After a reboot its possible to create a system image backup again.

This was not happening with Windows 8.1 Pro

How to execute a second System Image backup that will avoid this failure?

 

Compacting virtual hard disks

We must have totally different working methods

Let's see what I told to be my workflow, and check how that works in reality. Example W10 x64 VM is one I have used for ESDtoISO and UUPtoISO testing, a clean installed build 15048 with no additional software installed, upgraded several times to builds 15055, 15058, 15060 and 15061, always restored back to clean 15048. This has of course caused the VHD size to grow to multiple times what really is needed.

After the above, checking file sizes. Macrium image was made when the original 64 GB dynamically expanding VHD was 34.5 GB:




Macrium image size just under 5 GB:

After restoring Macrium image to a new dynamically expanding VHD, file size is 9.3 GB. Over two thirds smaller than original one:




The same as seen by File Explorer, yellow highlight is the original VHD, start situation, and green highlight the new VHD where Macrium image from old VHD was restored. Old VHD can now be deleted, net storage save savings over 25 GB in this example case:




(Notice that VHD has already grown over 0.5 GB since the previous screenshot a few minutes earlier. This is because in previous screenshot VM was not started yet after restoring the image.)
This of course is all logical, happens every time.

 

Windows Backup Problems

Having a problem backing up Windows 7, need help. Basically, I am having the problem in which the backup will not create at all and fails at the shadow copy. This happens in Windows Backup using both the disk image backup and the personal file backup. It goes to maybe 5%-8% of Shadow Copy depending on the backup type and fails. The error that comes in event viewer is 0x81000019. Yes the disk is brand new and double the size of C:.

I tried the fix of making a new 490mb system reserve partition and that did not help (http://social.technet.microsoft.com...l/thread/fce6950d-c06d-4dd0-a850-67022db4fe04) I formatted the disk several times and that didn't help. I tried a third party program, Comodo backup, and that too failed to operate I would say based on the shadow copy service. I tried this fix as well (http://social.technet.microsoft.com...aac-a0af-4740-a331-2b14d604a846?prof=required) and I failed at the regsvr32 es.dll, regsvr32 msxml3.dll, regsvr32 msxml4.dll commands, and WMI Writer when using the vssadmin list writers command was not responding. I've also tried stopping and restarting the service.

Besides doing a manual backup using Acronis, which is not preferred at this point, I don't know how to fix this.
