Acronis True Image 2021/2020 Starts Backup then Hangs After 24K
I purchased a subscription to, and installed ATI 2021 to upgrade my ATI 2020 installation which was working perfectly. When I tried to use it, the user interface was so slow as to be unusable. When I was able to start a backup, it copied 24K to the USB hard drive and hung. After trying this several times, I requested and received a refund for 2021, reinstalled 2020. Now I am having the same problem with 2020. My account page says my support for 2020 has expired, however, it was my purchase and installation of 2021 that created this problem. I ran manufacturer diagnostics on both the internal and external USB drives, which indicated no problems. Searching the web, I found the Acronis VSS Doctor, which I then ran. It indicated that 2 hidden recovery volumes on my main drive were out of disk space - these partitions have not changed and were never a problem before this upgrade. I have run out of ideas...

Thanks Steve. this did the trick!
I had never noticed the option to show 'Full Partition List'. The 2 hidden recovery partitions must have been deselected by default, as this was never a problem until now. I deselected them and it works ok now.

I am having the same issue, however, I have a Dell XPS8900 with an SSD drive. I have mine setup to dual boot on both the hard drive and the SSD drive. I keep the hard drive updated to use in the case of an SSD drive failure. The other partition on both is Windows 8.1. I originally had True Image 2016 on the hard drive in case the Acronis activation looked at the hard drive as another computer. The issue just started yesterday. I uninstalled TI 2016 and also ran the VSS tool from the Acronis site. It didn't help. I then uninstalled TI 2016 and installed TI 2021, only to experience the same issue. TI 2021 is extremely slow starting up and getting started saving the backup, but it still works on the SSD drive. I wanted to be able to image on the hard drive side since creating an image on the SSD side gives the two partitions (in the image) different drive letters, so I don't know what issue that would cause if I attempt to do a restore. I did have an SSD drive fail last year, so it is important to keep the hard drive sedtup in case I need it again. Everything is so much faster running Windows and programs from the SSD drive. Seems funny the issue of the imaging stopping at 24K on your drive nad mine. Makes it sound like an Acronis problem.

Ron, do you have ATI still installed on both your dual-boot copies of Windows?
As you have 2 different disk drives installed in your Dell PC, one HDD and a SSD, then I would always recommend making separate full disk backups of each drive - this to keep any future recovery as simple as possible as well as keeping the backup size smaller too.
Drive letters shown in the backup will depend on where you are making the backups from, i.e. if you are booted from the HDD (as C:) then the SSD will always have a different drive letter, and the reverse will be true too.
If you make the backup of the HDD from the HDD then drive letters will show correctly for that drive, the same for the SSD.
I would recommend trying to isolate this new issue to see which of your disk drives it is arising from? To do this, then do a single disk backup from just one of your dual-boot OS systems and see if the same issue is shown? If not, then repeat the same for the second OS system.
Note: it shouldn't matter greatly whether you use ATI 2016 or ATI 2020 other than the factor that the latter may be more sensitive to latent disk issues than the earlier version was!
