## Concepts

- All Buckets on MinIO are always in one of the following states: unversioned (the default) and all other existing deployments, versioning-enabled, or versioning-suspended.
- Versioning state applies to all of the objects in the versioning enabled bucket. The first time you enable a bucket for versioning, objects in the bucket are thereafter always versioned and given a unique version ID.

// ObjectsVersionCountIntervals is the list of all intervals
// of object version count to be included in objects histogram.
var ObjectsVersionCountIntervals = [dataUsageVersionLen]objectHistogramInterval{
	{"UNVERSIONED", 0, 0},
	{"SINGLE_VERSION", 1, 1},
	{"BETWEEN_2_AND_10", 2, 9},
	{"BETWEEN_10_AND_100", 10, 99},
	{"BETWEEN_100_AND_1000", 100, 999},
	{"BETWEEN_1000_AND_10000", 1000, 9999},

		// any version, look for if the bucket is versioned or not.
		if objects[i].VersionID == "" {
			// MinIO extension to bucket version configuration
			suspended := opts.VersionSuspended
			versioned := opts.Versioned
			if opts.PrefixEnabledFn != nil {
				versioned = opts.PrefixEnabledFn(objects[i].ObjectName)
			}
			if versioned || suspended {
				// Bucket is versioned and no version was explicitly

		}
		// Destination is not versioned and source version ID is empty
		// perform an in-place update.
		if !dstOpts.Versioned && srcOpts.VersionID == "" {
			return z.serverPools[poolIdx].CopyObject(ctx, srcBucket, srcObject, dstBucket, dstObject, srcInfo, srcOpts, dstOpts)
		}
		// Destination is versioned, source is not destination version,
