Symptoms
A VM resurrection restore is performed using the NetWorker VMware Protection (NVP) vProxy appliance.The save set selected does not reside on a Data Domain device; it is a clone copy on an AFTD device.An automatic resurrection (clone) job is started to clone the save set back to a ddboost device before starting the recover job. The process fails reporting:

The clone job has completed successfully, but the restore job does not start. The NetWorker server's /nsr/logs/daemon.raw shows that the job was completed successfully:

NetWorker: How to use nsr_render_log
The cloned save set can be seen on a ddboost device using the mminfo command on the NetWorker server:
mminfo -avot -q ssid=ssid
This issue may only appear during resurrections of larger VMs. When a resurrection is performed on smaller VMs, the issue was not observed.The NetWorker server is 19.8.0.x or older.
Cause
This issue was raised to NetWorker engineering.
Resolution
A code fix for this issue was released in NetWorker 19.9.0.2; upgrade the NetWorker server to this release (or later).

Workaround:
Start the restore again; however, this time select the save set which was cloned to the ddboost device in the previous attempt. The resurrection process will not be started since the save set is on a ddboost device. The restore process begins.
