Error changing blob access tier to archive

Tim Dawson 0 Reputation points

We've got a storage container with thousands of blobs, and after a period of time elapses we change the access tier of older blobs to archive. This has always worked for us until a few months ago, when we started getting 400 errors back:

Blob access tier is not supported on this storage account type

After a couple of weeks, it started working again, and we figured Microsoft had fixed the error. But then a few weeks later our requests stopped working again, and haven't worked since.

This is a StorageV2 (general purpose v2) storage account with ZRS replication located in uksouth.

Our requests are made with the C# azure blob storage library, but using azure storage explorer to attempt to change the access tier produces exactly the same error, which I will attach.

    Hi @Tim Dawson - Thanks for reaching out.

    If we check based on region the archive tier is supported in the UK South Region,united-kingdom-west&products=storage

    However checking based on redundancy, the archive tier isn’t supported for ZRS account and below are reference links:

    So that seem to be the issue in here. If you have changed the redundancy you might the limitation. You can test with any supported configuration as well.

    Hope that helps!
