IBM Tivoli Storage Manager (TSM) Client 6.3.2 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• The Tivoli Storage Manager client do not retries the backup when
  a Volume Shadow Copy Services (VSS) transient error occurs.
  
  The Tivoli Storage Manager client considers several Volume
  Shadow Copy Services (VSS) errors to be transient.
  Transient errors are network errors or drives that are
  temporarily misbehaving that might require backup recovery.
  When one of these errors occurs, the client should, by default,
  retry the VSS backup process three times at 30-second intervals.
