Change Blob’s access tier

• Setting blob’s access tier:
  • By setting the default access tier (Hot an cool) for the storage account. Blobs in this account inherit this access tier until you explicitly override the setting for individual blob
  • By explicitly setting a blob’s tier on upload. you can create a blob in the hot, cool or archive tier.
  • By changing the existing blob’s tier with a Set Blob tier operation, typically to move from a hotter tier a cooler one

Manage data archival

• Archive a Blob:
  • Archival is a offline tier for storing a blob that is rarely accessed.
  • The Archival tier offers the lowest storage costs, but higher retrieval costs.
  • Data must remain in Archival tier atleast for 180 days.
  • When the blob is in Archival tier, it cannot be read or modified. To read or download the Blob, you must first rehydrate it to an online tier (Hot or cool).
  • Rehydration can take up to 15 hours depending on the priority you specify of the rehydration option.
• Archive the existing blob by changing the blobs access tier
• Rehydrate a blob by changing its tier

Configuring a Lifecycle Management Policy

• Azure storage Lifecylce management policy offers a rule-based policy that can be used to transition the blob data tot eh appropriate access tier or to expire data at the end of the lifecycle.
• A lifecycle policy acts on a base blob, and optionally on the blobs’s version or snapshots.
• A life cycle management policy is comprised of one or more rules that define a set of actions to take a task based on condition met. For a base blob, you can choose to check on of two conditions
  • The number of days since the blob was last modified
  • The number of days sind the blob was last access. To use this condition your mist first optionally enable access time tracking
• Creating or managing a policy

Object Replication for block blobs

• Object replication asynchronously copies block blobs between a source storage account and a destination account.

• Ensure your source and destination storage account’s are created

• Enable blob versioning
