[Reproduction Path] What operations were performed when the issue occurred
[Encountered Issue: Issue Phenomenon and Impact]
When backing up the br log start log, the end-ts was specified, but in actual operation, the timestamp did not end as expected.
Which version will support this parameter?

BR log cannot specify end ts, right?
I checked the latest official documentation and it doesn’t mention the end-ts parameter. Where did you see this usage? 
I saw this parameter in the source code, and it can be set.
The help documentation is a bit outdated. The -s option can be written locally, but the documentation doesn’t mention it.
It is estimated that there are relatively few users…
Have you found any other shortcomings?
Which documentation hasn’t been updated?
Take a look at which link is wrong and give a brief description. I’ll make a documentation modification suggestion.
It only mentions S3, but does not mention the local method.
Will this be fixed? Haven’t found anything else yet.
Yes, they will definitely improve the documentation.
It seems that you cannot specify an end time; you can only manually stop the task.
Can this be fixed by myself?
