Microsofts strategy on BITS?

I have noticed that there is very litle information around on the BITS
framework, the BackgroundTransfer NewsGroup seams almost dead and I can't
find very much anywhere else on the net.

- Is BITS somethign Microsoft see as as an internal service?

- Do Microsft encourage 3:ed party solutions based on BITS?

- What source of information (exact location) should I use to find answer to
any problems that might arrise? (To be able to solve and understand
problems is CRITICAL to a solution, not just the functionality of the
service in it self)

- Is BITS intended to be able to upload very large files (10GB+), or is that
not the intetion of the service?

- I have now written a wraper for me to use in .NET, are microsoft planing
on releasing ther BITS API in .NET? if so when?

No,

MS would not create such internal service as a part of a service pack or
official Windows release.
If it were, it would have been inside the windows resource kit.

To my bet guess, BITS is used by MS themselves on automatic Windows updates.

Good to know that Microsoft is committed to the BITS framework.

But what about the other questions?

- What source of information (exact location) should I use to find answer to
any problems that might arise? (To be able to solve and understand
problems is CRITICAL to a solution, not just the functionality of the
service in it self)

- Is BITS intended to be able to upload very large files (10GB+), or is that
not the intention of the service?

- I have now written a wrapper for me to use in .NET, are Microsoft planning
on releasing their BITS API in .NET? if so when?

Any information on them?

You found the newsgroup to be unsuccesfull for help. So we exclude that
source for now.

But looking in the MSDN I found your answer.

<answer
src="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/bits/bits/bg_file_info.asp">
BITS 1.2 and earlier: For HTTP downloads, the maximum file size you can
transfer is 4 GB; BITS cannot guarantee the successful transfer of files
over 4 GB.
If the URL contains Unicode characters that are not in the US-ASCII
character set, encode the Unicode string in UTF-8 before passing it as the
remote file name to BITS. If you do not encode the string, the HTTP server
may receive an incorrect URL and the job may enter error state.

</answer>

so It looks like you have to upgrade to BITS 2.0.


The latest release for XP (client) is here
http://support.microsoft.com/?kbid=842309
and the BITS windows 2003 beta I already posted. It might be even no beta
but official release already.

IIS 7 will be a real fluidly built 'pure hybrid' using managed and unmanaged
code. As far as I know, both ends will improve but I can't say that BITS
will become pure managed.

b.t.w., it is a myth, assuming that a service automatically improves or 'is
better' as soon as it is pure .NET. The fact is that .NET for 80% relies on
unmanaged code (such as wmi/COM/win32/ADSI etc)


Success!

So, what question is still left? Do you want me to post a specific quetsion
to the MS developers?
Is it about the 4GB range?

I have done some more testing...it seams like I have to problem with smaller
files as well. The stange thig is that the file is partly transfered, and
the request that fails is much larger then the others...

I have included an extract of my iis files where it shows a few good request
and then the one that fials

the question should be, undet wat circomstances does BITS report a
0x80070070 error when it infact is a huge amount of free space on the disk.

I've posted your question.
I would wait a few days and regularry check back. I can't force things

I apologize for the delay in getting back to you. I have responded to your
other posting. Below are my other comments under questions.

BackgroundTransfer newsgroup is not dead and very much thriving. The lack of
response on this newsgroup was only temporary. MSDN and the BITS newsgroup
(backgroundtransfer) are the best sources of information for BITS.

BITS is for anybody to use and not just an internal service.

Yes Microsoft does encourage 3rd party solutions based on BITS and there are
many already.

http://msdn.microsoft.com/library/de...about_bits.asp
and microsoft.public.windows.backgroundtransfer newsgroup

Yes BITS supports upload of very large files. We haven't placed any limit on
the uploads. As much as IIS can support. We have tested with files larger
than 4GB internally.

Yes a Microsoft version of the .Net wrapper for BITS is being planned. But
it hasn't been finalized how and when it will be released.

The user misconfiguration issue was resolved - user had a 1GB disk quota in
effect... so the 4GB upload tripped over the limit. Once the disk quota was
adjusted, large uploads did not have any problems.
