Azure Blob storage lifecycle management offers a rich, rule-based policy for Azure storage accounts. You can use the policy to transition your data to the appropriate access tiers or expire at the end of the data's lifecycle.
Azure Blob storage lifecycle management now supports expiration of append blobs.
The lifecycle management feature is free of charge. Customers are charged the regular operation cost for the Set Blob Tier API calls. Delete operation is free. For more information about pricing, see Block Blob pricing.
