Zorluk: OrtaPlanning Cloud Storage Buckets and Storage Classes

An enterprise SaaS platform generates automated database backup archives every night. Engineering teams require high-speed, immediate access to these backup files during the first 30 days to support rapid point-in-time recovery during software release cycles. After 30 days, access is rarely needed (less than once per year), but compliance regulations dictate that all backup files must be retained for 3 years and remain immediately accessible within milliseconds if requested during an audit. Which Cloud Storage configuration meets these requirements while minimizing total cost?

  1. Set the bucket's default storage class to Standard, and configure an Object Lifecycle Management rule to transition objects to Archive storage 30 days after creation.Cevap
  2. B
    Set the bucket's default storage class to Archive storage at bucket creation so all backup files are written directly to the lowest-cost tier.
  3. C
    Set the bucket's default storage class to Standard, and apply per-object Access Control Lists (ACLs) to change individual object storage classes to Archive 30 days after creation.
  4. D
    Set the bucket's default storage class to Standard, and configure an Object Lifecycle Management rule to transition objects to Nearline storage after 30 days and delete them after 90 days.

Cevap

Set the bucket's default storage class to Standard, and configure an Object Lifecycle Management rule to transition objects to Archive storage 30 days after creation.
The solution requiring Standard storage for the first 30 days followed by an Object Lifecycle Management transition to Archive storage optimally aligns with the workload profile. Standard storage avoids retrieval fees during frequent early recovery operations, while Archive storage provides the lowest cost tier for long-term retention beyond 30 days while ensuring millisecond latency when compliance audits occur.

Adım Adım Çözüm

1
Analyze access frequency during the initial 30-day window.
Standard storage is appropriate because data is accessed frequently for potential point-in-time recoveries and has no minimum storage duration requirement.
Using cold storage tiers during active recovery periods would incur high retrieval fees.
2
Analyze access frequency and access time requirements after 30 days.
Data is accessed less than once a year but requires millisecond retrieval speeds for audits.
Archive storage offers the lowest cost per gigabyte for long-term retention while preserving millisecond access times.
3
Select the automation mechanism for storage class transition.
Configure Google Cloud Storage Object Lifecycle Management with an `Age` condition of 30 days and a `SetStorageClass` action targeting `ARCHIVE`.
Object Lifecycle Management automates transitions seamlessly without application code changes or manual intervention.
