Getting this error

[cobhc82]

Installed 2.1.0 and no errors anymore. Thank you

I'm evaluating Cobian Reflector 2.4.00 as a potential replacement for the File History feature in Windows, that Microsoft has badly broken with Windows 11 22H2.

I'm getting "ERR 2023-07-16 21:29:05 An error occurred while copying [...]: The media is write protected" for each and every file in the OneDrive sync folder that is marked "online-only" (attributes = 0x00501620).

It's OK that the files don't get backed up, since I don't want the backup to pull everything from the OneDrive cloud, which would most likely cause a "disk full" error.

It's just weird that those skipped files are reported as errors, furthermore with that inappropriate error message.

[cobian]

This "error" is repported by the OS and forwarded by the program.

How can you possibly get this error from a Windows system call?

Can you elaborate on how to access the file so that it prevents the Files on Demand mechanism from pulling the file from the cloud?

[cobian]

The CopyFileExW that I am using (an API Windows call) just will try to copy the files but because they don't physically exist then the OS resports that error.

[sba923]

What value are you using for dwCopyFlags?

If that value is 0, copying an "online-only" file will not fail, but will pull the file from the cloud via the OneDrive sync client.

Obviously that's not what happens, so you're probably using some non-zero flag combination.

I have a C++ test program ready to check what happens in that case...

[cobian]

Yes, I'm using another combination of flags, but I've been doing that sicnce the days before the cloud so I'll re-visit this part of the code.

[sba923]

Great! So we can expect an update where a backup of the OneDrive sync folder will backup what's "available on this device" and silently skip what's "online only"!

That's a must for me switching from Windows' File History to Cobian Reflector!

If you need testers for a preview build, you can count me in!
