Removable storage cannot be ejected

[Carabao2016]

Case 05611293

Hello,
My backups work fine but I have set that my storage must be ejected when the job has finished.
This worked well in the past without problems.
Now I get a warning after the backup job has finished. "Removable storage cannot be ejected."
How to solve this?
I tried uninstalling and reinstalling Veeam. The problem still exists.

Regards
Martin

Have you checked the O/S event logs. I suspect this may be an O/S issue. Also worth checking the uptime on the server.

[Carabao2016]

Thank you for your reply.
Where to check this?
The storage is a local USB storage, not a server.

Windows event logs are what i was refering to. Right click on the start menu select run and enter eventvwr.msc and press enter.

Also the job logs in %programdata%\Veeam are a great help too.

Does this help somehow?

Hello Georg,
thank you for your reply.
I checked this and there are no options for Removal Policies. Only the Write-Caching Policy is displayed.

Hi Carabao2016,

how about if you perform eject removable storage before backup run? is it okay or not?
also you might check if there any other program access your removable storage like Anti Virus

[Carabao2016]

Hi barlid,

sorry, I don´t understand...

[barlid]

Hi Carabao2016,

No Prob, I mean, can you do some testing to your USB storage to try eject "I:\" Drive manually from Windows Explorer? How is the result?

[Carabao2016]

Ok, I already tried to figure this out.
I see no option to eject it.
My drive has no options or removal policies at all.

[barlid]

Yes, thats why we see this error when Veeam try to eject it,
"Cause: The device does not support the specified operation"

You need to check your policy settings, then ensure you can eject the USB storage manually, then it should be solve your issue.

Thanks
barli

[Carabao2016]

Hello barli,

I agree, this seems to be the issue. But where to check this?

[barlid]

Hi Martin,

In normal condition the eject option should be shown when you right click on USB Storage, have you try these below action before?

• Restart Explorer, Plug & Play Services.

• Restart your computer

• Try to test plug other USB Storage devices, if not issue on other USB storage, you need check to USB Storage vendor related new drivers.

Thanks

[Carabao2016]

Hello Barli,

now I tried something I should have tried long before: I plugged the external storage to a different USB Port.
It works as expected.
I wasn´t aware of that the USP ports are handeled so differently by the system - some are ejectable and some not.

I really don´t know what the technical background is here but it works now and my storage ist automatically ejected when the backup job is done.

Thank you all for helping me!

Martin

Hi Martin,
Good to hear your issue was solved.

Thanks

Please be aware that "ejected" USB devices can be remounted via a trivial operation on that machine. While I've seen this offer some real-life protection before, please don't think that just because it's ejected that it's safe from an attacker that could get onto the machine because they can just trigger a remount and access / destroy the backups.
