- A
Enable Bigtable managed backups with a retention policy of 7 days and a restore to another cluster.
Correct. Bigtable managed backups with 7-day retention can be restored to another cluster in a different region, providing point-in-time recovery within the last week.
- B
Use Bigtable managed backups with a 7-day retention, and restore to a cluster in the same region; then replicate to the DR region.
Why wrong: Incorrect. Restoring to a cluster in the same region and then replicating adds complexity and delay. Managed backups can be restored directly to a different region.
- C
Use Bigtable replication across two instances in different regions, with a scheduled script to take snapshots.
Why wrong: Incorrect. Replication alone does not provide point-in-time recovery. Scheduled snapshots may not capture all moments and are not as reliable as managed backups.
- D
Export Bigtable data to GCS using a Dataflow template daily, and store backups with object lifecycle management.
Why wrong: Incorrect. Exporting to GCS via Dataflow does not support point-in-time recovery within Bigtable; it is a batch export that may not capture real-time changes and requires additional steps to restore.
PCD Bigtable Managed Backups Practice Question
This PCD practice question tests your understanding of manage a solution that can span multiple database systems. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: bigtable Managed Backups. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Cloud Bigtable for real-time user sessions. They need to back up Bigtable data to another region for disaster recovery, with the ability to restore to a specific point in time within the last week. Which backup strategy should they choose?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable Bigtable managed backups with a retention policy of 7 days and a restore to another cluster.
Bigtable's managed backups (also called backups) allow you to create backups with a retention policy (up to 7 days for point-in-time recovery). These backups can be restored to a different cluster, even in a different region, enabling cross-region disaster recovery. This meets the requirement for point-in-time recovery within the last week. Option A correctly describes this strategy. Options B, C, and D either introduce unnecessary steps or do not provide point-in-time recovery.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates often confuse Bigtable replication with backups. Replication provides real-time replication but does not offer point-in-time recovery; backups are necessary for point-in-time restoration.

Key takeaway
Bigtable Managed Backups
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
