UrBackup to Azure Blob Storage Hot or Cool


What is the best storage tier to use for Azure Blob - hot or cool? Trying to keep costs down, but not sure if cool will end up costing more with how the appliance reads the existing data in the blob.

Depends on a lot of factors:

  • A large factor is the size of the cache
  • How frequently the backed up data is changing in combination with the amount of time you are keeping backups
  • How much data you are storing (in relation to cache size)

Unfortunately Azure doesn’t have something like intelligent tiering, I guess? I have no experience there but can you build something like this via Optimize costs by automatically managing the data lifecycle - Azure Storage | Microsoft Learn . E.g. make a rule that data moves from hot to cool after 30 days.
