  • Closed as program error.

Error description

  • The GENERATE BACKUPSET command can run for a long time (for
    example compared to a MOVE NODEDATA) when the source is spread
    over many non-collocated volumes.
    By design of the GENERATE BACKUPSET function, it cannot reach
    the speed of a MOVE NODEDATA, but with improved and better usage
    of DB2 internal views, the performance can increase quite well
    (several minutes vs. some few hours).
