Oracle Error Message
RMAN-06755: WARNING: datafile string: incremental-start SCN is too recent; using checkpoint SCN string instead
Reason for the Error
The incremental-start sysetm change number (SCN) which was specified when starting an incremental datafile backup is greater than the datafile checkpoint SCN, which could cause some blocks to be missed.
Solution
Specify a smaller incremental-start system change number (SCN).
