Explanation
Long-term storage is used to store the data accessed rarely or mostly saved for archive purposes. It should not be used to store backup data than must be restored in two hour since data in the long-term storage can take several hours to retrieve depending on the specified rehydration priority. Back up to object storage every hour or three hours both accommodate the requirement of RTO and RPO. However, the option of backup every three hours is less expensive.
