NetWorker: Staging fails for Block Based Backup
Podsumowanie: NetWorker Staging is failing for Block Based Backup (BBB)
Objawy
NSRCLONE_PROCESSING_PHASE_TWO stage while attempting to obtain the Save Set ID and Clone ID information. The workflow identified the save set as a Block Based Backup (BBB).
As a result, the save set was skipped, and the job failed with the message "

Rozwiązanie
Staging or migration operations (nsrclone -m) are not supported for Block Based Backup (BBB) save sets due to a product limitation in NetWorker.
As an alternative, perform a standard clone operation to copy the BBB save set to the required target volume or pool. This creates an additional copy of the save set while retaining the original copy.
If the objective is to move the data permanently from the source volume, NetWorker does not provide a supported staging or migration method for BBB save sets. The closest alternative is to create a clone copy and subsequently allow the original save set to expire according to retention policies; however, this does not provide the same functionality or guarantees as a staging operation.

- Contains detailed documentation on save set management, including the section "Staging save sets from the command prompt", which covers both staging and cloning operations, supported scenarios, and operational considerations.
These resources can be used as references for understanding the differences between cloning and staging, as well as the limitations associated with Block Based Backup (BBB) save sets.
