Server 2008 r2 backup error 2155348001

Server back is failing with error code 2155348001.

I saw a fix on several sites, including technet, to create a Timeout key in the registry with a time of 20 minutes because it is taking Backup more than 10 minutes to make the Volume Shadow Copy.  Did that; with  (key value = decimal 12000000 which the answer said = 20 minutes).  Ran a one time backup.  Still failed, but the only effect of the registry entry seems to have been for it to have taken 4 hours from triggering the job to the appearance of the error in Event Viewer.

Does anyone know the right answer?  The other answers floating around out there aren't helping.

What's the size of the USB disk your are attempting to use for a backup?

What errors do you get in Events during backup attempts?

Ah!  Interesting. I'm using a 4TB Western Digital Elements.

Wouldn't/shouldn't Windows Backup with it is "preparing" the disk fix any sector size issues.  Or is sector size hard coded into the hardware?

I don't have the error message with me now, but when you google "Server 2008 r2 backup error 2155348001" you'll see what I saw.  Backup itself says it could not create the Volume Shadow Copy, and it never starts the backup.
>4TB Western Digital Elements.
That's your issue.
Anything > 2tb will NOT work.
It's an issue with the built in backup in server 2008.
They fixed it in 2012.
You'll need a smaller disk<2tb or a 3rd party backup.

The 4k block size is fixed at the factory.
So get another model disk.
I know the WD reds work as they are still 512byte in their <2tb models.

The problem was not in disk size but in the physical sector size of the HDD. Some of these big HDDs which physically have 4K sector size can emulate 512byte sector size layer. And the drive can even be 500GB and have the same 4K sector size.
To narrow the problem to its bottle neck I would suggest you trying to take backup to a network share. If it works there - then the problem is in your WD drive.
If it does not work when taking backup to network share - then the problem is in Windows Server Backup itself.

Many thanks for all this.

I've been looking at 3rd party backup software now, Acronis specifically, as a better alternative for backing up my three servers running Server 2008 R2 than getting three new 2 TB WD MY Book or Elements external drives.

The information about Acronis seems to indicate that it also provides "system state" backup like Windows Server Backup.  Is that so?

And am I correct in inferring from your answers to my question that I would be able to use my 4TB Essentials drives if I use Acronis instead of Windows Server Backup?

Ouch!   I just looked at prices at Acronis for versions for server backup.  Many, many times more than I was seeing on Amazon for Aconis True Image.  What's the diff.  Could I not just use $36.00 True Image product?  Instead of their $999.00 Backup for Windows Server product?

More about my environment. Three Server 2008 R2 machines in an AD domain, with about 20 workstations.  One machine is dedicated to be an on-premises Exchange Server.  One on of the other two runs two applications (a room scheduling system and a membership database and hosts users data in home directories.  The other of the two runs nothing and is just backup hardware and a location for backups of user data.

Related question.  If I have a hardware failure on my primary app server and have a full backup, can I restore to the backup server?  It seems obvious that the answer would be yes, but ...

It won't install.

I personally use Symantec SSR 2013 for my standalone servers.
About $600 bucks or less.

Thanks again.  Just to close out, I've decided to go with WD My Book 2 TB drives.  It's an inexpensive enough next step.
