Windows 2012 Server back-up failing

[Orthix]

Hi All,

 

I have the following setup:

Windows 2012 R2 Essentials

C Drive: OS, separate SSD

D Drive: Drive Pool

 

When configuring the server to back-up just the C drive, it completed 100%

 

When configuring the server to back-up the C drive and any folder within the D drive, it fails. I get the following error:

VssAdmin: Unable to create a shadow copy: The shadow copy provider had an error. Please see the system and application event logs for more information.
Command-line: 'C:\Windows\system32\vssadmin.exe Create Shadow /AutoRetry=15 /For=\\?\Volume{19eaedff-5798-4255-bb2b-59dafb1f82a0}\'.

 

 

Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{19eaedff-5798-4255-bb2b-59dafb1f82a0} - 00000000000001D4,0x0053c008,000000A9E05887F0,0,000000A9E058BB90,4096,[0]).  hr = 0x80820001, The bootfile is too small to support persistent snapshots.

Any help is appreciated.

Unfortunately, we don't support using Windows Server Backup to backup the pool directly.

Specifically, it relies on Volume Shadow copy Service (VSS) working in the drive. However, there is absolutely no documentation on how to support VSS on the file system, so to add support would require extensive reverse engineering, to get it working.

 

However, you can back up the disks that make up the pool without any issues.

http://stablebit.com/Support/DrivePool/1.X/Manual?Section=Using%20Server%20Backup%20to%20Backup%20the%20Pool

Though, ignore the references to the 2TB limit as this doesn't apply to Server 2012R2 or up.

 

Alternatively, any file based solution does work here, such as robocopy/AllWays Sync/Free File Sync/etc.
