Does anyone know what storage classes are supported for Azure blob?
There are docs that mention AWS S3 archive tiers aren't supported for snapshot repositories, but do hot, cool, cold, and archive all work for Azure blob?
Thanks!
There's no setting to control the storage class on upload to Azure today but the Azure docs indicate you can influence the tier of blobs in various other ways. I'm not sure we've ever tried any tiers apart from the default hot one, but the Azure docs suggest that hot/cool/cold all look the same to the API so I'd guess they all work ok, whereas the archive tier looks to need extra rehydration steps and therefore will not work for much the same reasons as S3's Glacier tiers.
That said, tread carefully when doing anything to the contents of a repository yourself. The docs warn against doing so:
Don’t modify anything within the repository or run processes that might interfere with its contents.
Since we don't have tests to cover any non-hot storage classes in Azure we can't formally guarantee anything in this area, sorry.
