Troubleshooting › Backup Job Fails

Backup Job Fails

Symptom

A backup job failed with the following error message in the activity logs:

Reconfiguration for backup cannot be performed in the current state. Shut down the virtual machine and attempt to run backup job again. (The virtual machine can be powered on during or after the taking snapshot phase).

Solution

Set the registry values to not reconfigure disk.enableUUID.

Follow these steps:

Applies at the proxy level and all the VMware VMs are impacted.

1. Log in to the Backup proxy server.
2. Open the registry editor and locate the following key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine\AFBackupDll
   

3. Add a DWORD value with name DoNotReconfigDiskUUID and specify 1 as its value.

Applies at the specific VM level and only the specified VM is impacted.

1. Log in to the Backup proxy server.
2. Open the registry editor and locate the following key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine\AFBackupDll\<VM-InstanceUUID>
   

   Note: Replace <VM-InstanceUUID> with the UUID value of the virtual machine which this setting applies for. You can find the value in the URL of the virtual machine that is used when connected to the Arcserve UDP Agent.

3. Add a DWORD value with name DoNotReconfigDiskUUID and specify 1 as its value.

Be aware of the following points:

• The VM level takes precedence if both VM and proxy level registries are configured.
• If the registry does not exist, the registry value implies 0, that is, you have to reconfigure disk.enableUUID.
• If you specified not to reconfigure the disk.EnableUUID parameter, the backed up data may not be in a consistent state.
