This protects against accidental overwrites or deletes of objects, allows previous versions to be retrieved.

When you DELETE an object, all versions remain in the bucket and MinIO adds a delete marker, as shown below:

![delete](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/versioning/versioning_DELETE_versionEnabled.png)

			// TCP starts sending keepalive probes
			_ = syscall.SetsockoptInt(fd, syscall.IPPROTO_TCP, syscall.TCP_KEEPIDLE, 15)

			// Number of probes.
