Where are these mysterious log files containing the phantom error codes?

I’m not sure what you are asking.
Here is a list of error codes: https://forums.comodo.com/news-announcements-feedback-cb/comodo-backup-error-codes-t49652.0.html


Comodo BU was working just fine, but has started failing at 84%. Says error writing in backup, back up process failed with code 100665. I have checked the target disk and Win 7 chkdisk says it has no problems.
Thanks for your assistance.

FYI, that’s Win 7 Home 64bit. I am not compressing the files thru Comodo, but am writing to a compressed HDD. It’s a full partition backup of C:. As I said before the same procedure has worked flawlessly in the past.


This error indicates that the operation could not be completed due to a file system limitation.
What file system do you have on destination? You can try NTFS to avoid the issue.


It is NTFS, but the volume is compressed. I suppose that could impose some limitation. Thanks.
