Phase 2 Duplications reporting "Failed to get backup client" (81836)

Date: Feb 2010
Affected Product & Version : NVBU 8.5
Affected Module & Version : N/A
OS Version : any

Symptoms:
When the phase 2 duplication starts to run it reports "Failed to get backup client" and is unable to execute.

Explanation:

duplication job failing with the 'failed to get backup client' is generated by the following scenarios : -


1 - Any jobs that are created on a 8.5 server and are set to execute a duplicate on a client earlier than 8.5

2 - Any jobs that are created on a 8.5 server and for which the Phase 1 backup had to execute one or more retries .
It is not possible to avoid the phase 2 failure on a retried backup.

for scenario 1:

upgrade the client executing the duplication (as configured with advanced options) to NVBU 8.5

for scenario 2:

This fault is reported as Jira ref NVG-6022. Once fixed this will be reported in the NVBU release notes.

This will only occur if the phase 1 to be duplicated originally encountered an error requiring a job retry.
If the phase 1 completes successfully then the duplication will complete successfully.

Update: May 12, 2010
