A new configuration option improves backup performance by skipping non-transaction files and pre-image files during a dynamic dump:
PERMIT_NONTRAN_DUMP < YES | NO >
Default: YES
When set to NO, non-transaction files and pre-image files are skipped during a dynamic dump even if they are included in the !FILES section of the dynamic dump configuration script. The exception is if PREIMAGE_DUMP is set to YES, then pre-image files continue to be included in the dump.
