Bug: Disk Backupper Freezes the System

my system freezes completely while trying to make disc image backups from my system drive (full backup).
I use Windows 10 x64 on a lenovo ThinkPad T540p, and a Samsung SSD with basic disc layout.
The Problem is independent of using VSS or AOMEIs own alternative.
Backupper writes around 25 MB to the external (USB3) hard drive, and according to Windows Resource Monitor it reads a lot of data with maximum speed from system-ssd, but don't write anything to the target drive. After some minutes Backuper stops reading from source-ssd. The system drive is somehow completely locked for any writes, but system tasks reads data from the disc. Because of the ongoing write lock the system freezes and i need to make a hard reset. I am somehow perplexed.

Thank you for any help.


  • Can you upload some screenshots of this problem?

  • Came here to find this very issue.  I'm experiencing the same thing, thought it was a system freeze because of a hardware problem, but after enabling minidump files I noticed that the first 3 in a row were at 11:01 PM... exactly when I scheduled my Aomei backup.

    Each time it's happened, I've been playing World of Warcraft at the same time and the system completely locks hard -- I lose two of my monitors and the main one freezes on whatever picture happened to be up. Most of the time the sound will be buzzing loudly if a sound happened to be playing at the time.  The only solution is a hard reset via the reset switch; there is no interaction with the computer keyboard that functions.

    I've been working on it for a while and original thought it was drivers, so have updated every driver in the system to the newest version of what's out there. I'm running an MSI Z170 Titanium board with a Core i7 6700k, 32gb of DDR4/3200 G.Skill memory, and a Samsung 950 NVMe SSD.

    JUST updated AOMEI to 4.0.3 and have rescheduled a backup for 4 AM.  It seems to run fine if I've just brought the computer out of sleep and it immediately backs up the missed schedule, but locks up when running other things.

    Will be happy to do additional troubleshooting.

  • @Alyred When the system freezes, what's the interface of Backupper?

  • How do you mean?  There's no interface loaded; the entire system just solid locks with no response and has to be hard reset with the switch. There's no way to see what the status of any other program is.

  • Also note, that it's only been since yesterday that I tracked the issue to Backupper, as was the third time in a row it locked up at exactly 11:00 PM and I was able to correlate that with the backup schedule and tie the issues beginning to when I had installed the upgraded version and bought a licensed copy, and re-created the backup at 11 PM instead of 1 AM where I had it before.

  • After rebooting the computer, does the program work well?

  • It doesn't seem to cause any more problems after rebooting, but I don't try to run the backup immediately after restarting.

    It did run at 4:00 this morning while I was still playing a game. Perhaps the newest version fixed an issue, but I will see what happens with the scheduled backups over the next few days.

    Hi, I see several discussions here on Aomei freezing while backingup in Windows. This discussion is not the newest but is closest to my situation. Any resolution? I have Aomei scheduled to backup my C: drive on Sunday at 18h12 (6:12 PM an arbitrary time when I'm likely away from the computer). Every Sunday when I come back to the laptop later in the evening, the clock on the task bar is frozen at 18h15 (6:15 PM). I can move the mouse but cannot left or right click. The keyboard is non responsive, not even CTRL-ALT-DELETE or ALT-F4. I can't click on the X to close windows. Only solution is to hold down the power switch until the laptop shuts abruptly down. 

    Starting up I startup in Safe Mode then shut down and restart normally again. Laptop (Lenovo Thinkpad) works fine  until next Sunday. If I don't start in safe mode, the laptop (Windows?) goes through a disk check that takes about 20 minutes then Windows starts normally. 

    It is Jan 8, 2018 and Aomei Backerupper Professional is at version 4.0.6 which Aomei update reports as the current version. Any resolution? Aomei used to work but in this freezing problem has come up in the past 3-4 months and I don't have a backup since.


  • @Tonyw ; Can you please provide the following information to better analyze the problem?
    1. The log files in AOMEI Backupper installation directory and tasks2.2.xml file in "C:\ProgramData\AomeiBR".
    2. Download and run winobj tool to see if there is a "ambakdrv" under Driver.
    3. Check if there are security protection softwares on your computer.
    4. Export system logs in Event Viewer.
  • Like Tonyq I've having the same problem after scheduled backups. The system becomes unrepsonsive after first use although I can move the mouse. I ran the Winobj tool and I do have the ambakdrv. The log just says successful backup. Any help would be appreciated. I have Backupper Pro 4.05 (the latest) running on Windows 10 Pro x64 32GB. The backup is not using VSS and it's for the C drive which is on a Samsun 950 Pro NVME SSD.
