I’m sorry, but this is too vague to comment on. Please be very specific, providing actual messages.
Clarify this, for example did it fail mid-backup or fail during verification as in my recent explanation?
If the latter, can you look at one bad file as I showed? Do you have Linux? Analysis tools are better.
Generally it’s best to stay near defaults until things stabilize, however I’ll make selected comments.
Somewhat dangerous. Is there a need? Is this Windows? Any recent one should be fine without this.
“The process cannot access the file because it is being used by another process” potentially occurs, however I don’t know if that’s one of the errors you saw. If it is, try leaving this one at default of false.
This looks odd. Is it edited?. This is supposed to be a file path, as in your second list of your settings.
Why two somewhat similar but not identical lists? Is first Default options for some reason? Confused.
