Zorluk: ZorBackup and Restore Management

A company is designing a backup and disaster recovery strategy for a critical multi-tier application. The application stores transaction logs in an Amazon S3 bucket and uses an Amazon RDS for PostgreSQL DB instance. The backup policy requires all database backups to be replicated to a secondary AWS Region to enable point-in-time recovery (PITR) with a minimum recovery time. Additionally, the S3 transaction logs must be replicated to the secondary Region while retaining full version history. Which combination of actions should the SysOps Administrator take to meet these requirements? (Select TWO.)

  1. Enable versioning on both the source S3 bucket and the destination S3 bucket, and configure S3 Cross-Region Replication (CRR).Cevap
  2. Enable cross-Region automated backups replication for the Amazon RDS DB instance to replicate automated backups to the secondary Region.Cevap
  3. C
    Configure Amazon S3 Cross-Region Replication (CRR) on the source S3 bucket without enabling versioning on the destination S3 bucket.
  4. D
    Configure an Amazon RDS Read Replica in the secondary Region to serve as the automatic failover target for point-in-time recovery if the primary DB instance fails.
  5. E
    Create an S3 lifecycle rule to transition replicated objects directly to the S3 Glacier Flexible Retrieval storage class within 15 days of creation.

Cevap

To meet the requirements, the SysOps Administrator must enable versioning on both the source and destination S3 buckets and configure S3 Cross-Region Replication (CRR), and enable cross-Region automated backups replication for the Amazon RDS DB instance.
Enabling versioning on both the source and destination S3 buckets is a prerequisite for configuring Cross-Region Replication (CRR). Replicating RDS automated backups to a secondary Region provides the capability to restore the DB instance to any point in time within the backup retention window in the destination Region.

Adım Adım Çözüm

1
Enable versioning on both S3 buckets.
Both source and destination S3 buckets are versioning-enabled.
S3 Cross-Region Replication (CRR) requires versioning to be enabled on both the source and destination buckets to function properly.
2
Configure Cross-Region Replication.
S3 objects and version history are automatically copied to the secondary Region.
This configuration satisfies the S3 replication requirements while maintaining version history.
3
Configure Amazon RDS cross-Region automated backup replication.
RDS automated backups are replicated to the secondary Region.
This allows the administrator to perform point-in-time recovery (PITR) in the secondary Region directly from the replicated automated backups.
