| ERROR | KEEP ... NOLOGS option cannot be used when datafiles are fuzzy |
| CAUSE | The KEEP ... NOLOGS option was specified for a backup or copy of files in a fuzzy state. This kind of backup requires archived logs for recovery, so archived logs must be kept. |
| ACTION | Remove the KEEP ... NOLOGS option or make sure the files are not in a fuzzy state and resubmit the command. |
