Error description
With version 7.1 server with node attribute "SPLITLARGEObjects" enabled, it can happen that backup stgpool can report success but not actually backup certain files to the copy storage pool. This can happen when the first fragment(s) has been sent to the copypool already and backup stgpool retries as the whole object has not been sent. For example, running consecutive backup stgpool commands, it can be seen that same 6 items are reported as backed up each time. 06/01/2014 11:08:52 ANR0986I Process 4756 for BACKUP STORAGE POOL running in the BACKGROUND processed 6 items for a total of 45,374,028,876 bytes with a completion state of SUCCESS at 11:08:52 AM.
