backup to re-attached vhdx error CheckLastVolumeDeviceIdMatch

Thread needs solution

Hello Forum,

is there any way to backup to a re-attached vhdx?

If i detach vhdx file after backup and reattach it and start backup it fails with CheckLastVolumeDeviceIdMatch.

To solve this i have to reassign target folder (on vhdx) in backup job.

Drive letter and folder does not change by detach und reattach vhdx. Acronis seems to use some kind of id for backup target.

 

Any ideas? Maybe solved in newer versions?

 

Thank you.

 

Kind regards,

Chris

Chris, this sounds to me like the error message is telling you correctly, that the uniqueid for your VHDX virtual disk has changed and thus you need to reselect this in the target backup location for ATI.

You should be able to check this by using Diskpart from an Administrator command prompt.

C:\WINDOWS\system32>diskpart

Microsoft DiskPart version 10.0.17134.1

DISKPART> list vdisk

  VDisk ###  Disk ###  State                 Type       File
  ---------  --------  --------------------  ---------  ----
  VDisk 0    Disk 2    Attached not open     Expandable  J:\Virtual\test.vhdx

DISKPART> select disk 2

Disk 2 is now the selected disk.

DISKPART> uniqueid disk

Disk ID: {7E1C4BC9-1A22-4000-9977-C258597B3C14}

I have just tested this scenario (as I understand it) in ATI 2019 and had not errors when detaching then re-attaching the VHDX virtual disk being used as the backup destination, so no need to reselect the destination for these actions.

Using Powershell to view the virtual disk information shows that each detach / attach does result in a minor change to the path for the vdisk.
