    Hi,

    The limit for a block blob is 200GB, so I doubt this is the issue. Could you show some of the code and the (WCF) configuration you're using?

    thanks.

    i used that httpWebRequest async method in the silverlight instead of wcf to upload.

    Hi,

    How do you upload the big file in Blob Storage? You use HttpWebRequest to access the Blob Url and convert your file to stream, and give stream variable to HttpWebRequest.GetRequestStream() method? And about "successful upload to less than about 250M, but over about 250M files are upload faild.", do you ever get any exception messages when request was "failed"? I think if you can provide more details about your problem, it will help us to fix your problem quickly.

    An recommended way to upload large files via Blob RESTful service is divede the file to multiple file blocks. For example, you can divede the a large (such as 1000 Mb) file to 20 of 50Mb file blocks and upload all blocks with multiple web requests. HttpWebrequest will timeout while a long time without any response.

    Hope this helps.

    Are you going directly to the blob storage? Or are you going through a (WCF) service?

    Hi,

    Do you ever get any exception messages when request was "failed"? For example, you can got error code and stack message when exception was thrown.

    Hi,

    Did you still have this problem?  Try to use Azure Storage Exploer or WCF service to upload large file, if they works, i think the problem is caused by Silverlight client.

    I've tested a 500 Mb files at my side (divide to 20 Mb blocks) and works fine.

    Hope this helps.
