SBS2011 Backup Failing

Long story short - Based upon the answer to a previous question posted to EE, I purchased 4 Seagate Expansion External Hard drives to use to run backups with my SBS2011.

I received the HDs today. I took 1 and set it up and instructed the server to run a back up.

It failed.

Error message is  “One of the backup files could not be created. Detailed Error: The request could not be performed because of an I/O device error”

Event Viewer also shows:

Source: Microsoft-Windows-Backup
“failed with following error code ’2155348010' (One of the backup files could not be created.). Please rerun backup once issue is resolved.“

Any ideas how to get the backup to run?

Thanks - David

Hi David,

Try using a different USB Port first off.  

Check the Event logs to see which drive the I/O error was on.

I have tried 2 different hard drives and tried different USB ports.

Same errors no matter what I do.

I have a customer with a similar issue. The problem is that even by properly ejecting the USB drive and connecting the next drive, the system does not properly let go of the drive and therefore the next drive is not recognized. After that, even putting the original drive back in is no longer recognized.

The only work around I could come up with was scheduling a reboot of the server an hour prior to the backup. The user rotates the drives like normal, then the reboot cures the recognition issue and the backup is performed.

This is by no means a fix...just a workaround for an issue I have yet to be able to solve.

the issue can easliy be fixed.

u can use a tool called USBDLM, works wonders!

install the application and runs as a service. i installed this on many of my clients sbs servers.
