I too am a new Comodo customer who, like you, encountered CBU code 100 and internal errors (error code 112152 in my situation).
Initially I was running Comodo Backup version 126.96.36.199 on Windows 7, and was told by “Geek Buddy” that the CBU version I had been instructed to install was old and held known problems i.e. there is/was a link on the Comodo new customer web page that installed a bad version of CBU.
What version of CBU are you running? If 4.2.x, then you need to update to 4.3.x, using the following URL:
With CBU 4.3.x the code 100 errors went away, but next, I began encountering undefined code 9 errors. For that troubleshooting line, refer to my “What is the undocumented error code 9 ?” thread.
The short story on internal and other errors is to troubleshoot them with dbginfo, used as shown below.
I hope that this information helps. Even with the many CBU errors and it’s poorly focused documentation, I think that once I can get it to work, it will work well. I suspect that the errors now seen in my installation resulted from my beginning to use the product in the middle of Comodo’s conversion of Online Storage to include all the cloud services (CCloud, Comodo Online Storage and C-Drive) - that conversion even caught Comodo’s own support unaware.
On my Windows 7 OS, running the current CB, I searched for dbginfo.bat, leaving the resulting MS Explorer window up, and…
Reproduce the CB problem situation, noting the time to the minute.
Right-click on dbginfo; “Run As Administrator”:
C:\Program Files\COMODO\COMODO Backup\dbginfo.bat
This produces a compressed archive of the following format:
Run the archive, bringing up the CB interface for selecting a folder to extract the archive to.
Sort the resulting log files by modification date, and review their contents by the date/time-frame of interest.
