A company stores database backup files in an Azure Blob Storage container. To reduce storage costs, an Azure lifecycle management policy automatically transitions these files to the Archive storage tier 7 days after creation. A database administrator needs to test a backup restore process by running a validation script that reads the binary contents of a backup file created 15 days ago.
Which action must the administrator perform before running the validation script?
- AGenerate a Shared Access Signature (SAS) token with Read permissions and append it to the blob URL.
- Rehydrate the backup file by changing its storage tier to Hot or Cool, or by copying it to a new blob in an online tier.Cevap
- CAccess the backup file directly using the Azure portal's built-in Storage Explorer tool.
- DSubmit a support ticket asking Microsoft to perform the validation, as Microsoft is responsible for guest data backups in Infrastructure as a Service (IaaS).
Cevap
Rehydrate the backup file by changing its storage tier to Hot or Cool, or by copying it to a new blob in an online tier.
To read or access the data within a blob that is in the Archive storage tier, the data must first be rehydrated to an online tier (Hot or Cool). This can be achieved by changing the tier of the existing blob or by copying the archived blob to a new blob in an online tier.
