ReadonlyALWAYSAlways overwrite destination objects unconditionally. Use with caution - may cause data loss in destination. Suitable for full bucket synchronization.
ReadonlyIF_Overwrite only if source object is newer than destination. Comparison based on Last-Modified timestamp. Recommended for incremental sync scenarios.
ReadonlyNEVERNever overwrite objects that exist in the destination. If object exists in destination bucket, skip it. Safest option to prevent data loss.
ReadonlyOVERWRITE_Represents the OVERWRITE_STRATEGY_UNSPECIFIED protobuf enum value.
