Specifies how and when DataSync checks the integrity of the data during a transfer.
| value | description |
|---|---|
| ONLY_FILES_TRANSFERRED | RECOMMENDED - DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination. |
| POINT_IN_TIME_CONSISTENT | DEFAULT - At the end of the transfer, DataSync scans the entire source and destination to verify that both locations are fully synchronized. |
| NONE | DataSync doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer. |
