Case # 05467141
Veeam Support recommended me to create this thread here

We would like to use archive storages without ever using the regular object storage which is hot/cold tier.
Unfortunately now, almost all of our problems on VBO related to VBO server with object storage, so we prefer file storage instead of object storage, where we almost don't have problems. (problems: 90% object stor. vs 10% file stor.)
Because of this, unfortunately we can use archive object storage.
If anyone has a similar problem or it makes sense to someone, post it here.
Best regards,
Jan
