Implement Blob storage lifecycle policies

• You can add, edit, or remove a policy by using any of the following methods:
  • Azure portal
  • Azure PowerShell
  • Azure CLI
  • REST APIs
• A lifecycle management policy must be read or written in full. Partial updates aren't supported.

Azure portal

• There are two ways to add a policy through the Azure portal: Azure portal List view, and Azure portal Code view.

Azure portal List view

1. Sign in to the Azure portal.
2. Select All resources and then select your storage account.
3. Under Data management, select Lifecycle management to view or change your rules.
4. Select the List view tab.
5. Select Add rule and then fill out the Action set form fields. In the following example, blobs are moved to cool storage if they haven't been modified for 30 days.
6. Select Filter set to add an optional filter. Then, select Browse to specify a container and folder by which to filter.
7. Select Review + add to review the policy settings.
8. Select Add to add the new policy.

Azure portal Code view

1. Follow the first three steps in the List view section.
2. Select the Code view tab. The following JSON is an example of a policy that moves a block blob whose name begins with log to the cool tier if it has been more than 30 days since the blob was modified.

{
  "rules": [
    {
      "enabled": true,
      "name": "move-to-cool",
      "type": "Lifecycle",
      "definition": {
        "actions": {
          "baseBlob": {
            "tierToCool": {
              "daysAfterModificationGreaterThan": 30
            }
          }
        },
        "filters": {
          "blobTypes": [
            "blockBlob"
          ],
          "prefixMatch": [
            "sample-container/log"
          ]
        }
      }
    }
  ]
}

3. Select Save.

Azure CLI

• To add a lifecycle management policy with Azure CLI, write the policy to a JSON file, then call the az storage account management-policy create command to create the policy.

az storage account management-policy create \
    --account-name <storage-account> \
    --policy @policy.json \
    --resource-group <resource-group>
