We have some functionality through a feature called SMTape - http://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-ptbrg%2FGUID-6B5C48F0-B5BF-47C9-B40E-CF03704E95E6.html
An important note though - You can restore data to volumes created across up to two major consecutive Data ONTAP releases only. This might not be suitable for 5-7 year retention.
