What is Google Cloud Backup and DR Service?

Managed backup service for VMs, databases, file systems. Centralized policy management, incremental backups, cross-region replication, instant recovery.

What is the difference between RTO and RPO?

RTO (Recovery Time Objective) = maximum downtime. RPO (Recovery Point Objective) = maximum data loss. Lower values = higher DR costs.

What DR strategies does GCP support?

Backup & restore (hours RTO), pilot light (minutes RTO), warm standby (seconds-minutes RTO), active-active (near-zero RTO). Choice based on business requirements.

How does cross-region replication work?

Asynchronous data replication between regions. Cloud Storage dual/multi-region, Spanner multi-region, Cloud SQL cross-region replicas, persistent disk snapshots.

How to backup Cloud SQL databases?

Automated backups (daily), on-demand backups, point-in-time recovery (binlog/WAL), cross-region backup copies. Backup and DR Service for centralized management.

Tabletop exercises for procedures, technical drills for failover, full DR test with application recovery. Document results, update runbooks, regular cadence (quarterly).

What is pilot light DR pattern?

Minimal infrastructure in DR region (database replicas, DNS), rapid scale-up at failover. Balance between cost and RTO. Typically minutes-hours RTO.

How to ensure consistency during backup?

Application-consistent snapshots (VSS/fsfreeze), database-native backup tools, quiesce application before snapshot, transaction logs for point-in-time recovery.

What are best practices for backup retention?

Tiered retention (daily/weekly/monthly/yearly), compliance requirements (GDPR, audit), cost optimization via storage classes, testing restore from different tiers.

How to automate DR failover?

Cloud DNS failover policies, load balancer health checks, Terraform/Deployment Manager for infrastructure, Cloud Functions for orchestration, runbook automation.

How to protect data from ransomware?

Immutable backups (object lock), air-gapped copies, backup encryption, access controls, regular restore testing, security monitoring for early detection.

Strategie zálohování a obnovy v Google Cloud: Backup and DR Service, immutable backups, cross-region replikace a runbook orchestrace.

RTO a RPO targets

Definice Recovery Time Objective (downtime tolerance) a Recovery Point Objective (data loss tolerance), tier classification, business impact analysis (BIA).

Backup and DR Service

Centrální backup pro Compute Engine, VMware Engine, databáze (Cloud SQL, SAP HANA, Oracle), incremental forever, application-consistent snapshots.

Persistent Disk snapshots

Incremental snapshots (jen změněné bloky), Snapshot Schedules, regional/multi-regional ukládání, cross-project sharing, snapshot retention policies.

Cloud Storage backup tiers

Nearline (30 dní min), Coldline (90 dní), Archive (365 dní), Object Versioning, Bucket Lock pro WORM compliance, Retention Policies.

Immutable backups a ransomware

Bucket Lock + Retention Policy = ransomware-proof, Backup Vault s isolation, oddělené credentials, 3-2-1 strategy (3 copies, 2 media, 1 offsite).

Database backups

Cloud SQL automated backups (7–365 dní retention), Point-in-Time Recovery (PITR), Spanner backups, AlloyDB continuous backup, BigQuery time travel.

Multi-region a dual-region

Dual-region buckets (geo-redundant), Spanner multi-region (5 nines SLA), BigQuery multi-region datasets, asynchronní cross-region replikace.

Disaster Recovery strategies

Backup & Restore (RTO hodiny), Pilot Light (RTO 10s minut), Warm Standby (RTO minuty), Hot Standby/Active-Active (RTO sekundy).

Global Load Balancer pro failover

Cloud Load Balancing s health checks, automatic failover mezi regiony, Cloud DNS routing policies (geo, failover), Traffic Director pro service mesh.

DR runbook a testování
