### 3.1 Automatic removal of non current objects versions

A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.

#### Verwendung von `StreamingResponse` mit dateiähnlichen Objekten

Wenn Sie ein dateiähnliches (file-like) Objekt haben (z. B. das von `open()` zurückgegebene Objekt), können Sie eine Generatorfunktion erstellen, um über dieses dateiähnliche Objekt zu iterieren.

# List the objects from replicated site
echo "Objects from replicated instance"
./mc ls minio2/test-bucket --insecure
repcount1=$(./mc ls minio2/test-bucket/plainfile --insecure | wc -l)
if [ "${repcount1}" -ne 1 ]; then
	echo "BUG: object test-bucket/plainfile not replicated"
	exit_1
fi
repcount2=$(./mc ls minio2/test-bucket/encrypted --insecure | wc -l)
if [ "${repcount2}" -ne 1 ]; then
