I understand you are looking for a solution to backup archived blobs. Please let me know if I am understanding the issue correctly.
While a blob is in the Archive access tier, it's considered to be offline and can't be read or modified. In order to read or modify data in an archived blob, you must first rehydrate the blob to an online tier, either the Hot or Cool tier. This is why it is incompatible with the solutions you are checking. Archive blobs are meant to be a backup or offline storage so there is not options to back them up.
Archive access tier supports LRS, GRS, or RA-GRS redundancy. If you are needing a backup perhaps using GRS will be enough for you. Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in a secondary region that is hundreds of miles away from the primary region. More information can be found on the Azure Storage redundancy page.
