Backup Cloud ibrido

L’adozione del cloud ibrido è in crescita, poiché le organizzazioni combinano sistemi on-premise con piattaforme cloud per gestire i dati in modo più efficiente. Per i team IT responsabili della protezione dei carichi di lavoro critici, questo approccio garantisce un equilibrio tra velocità di Recovery, convenienza economica e resilienza.

Oggi le aziende eseguono applicazioni in diversi ambienti. Una strategia di backup nel cloud ibrido supporta questa realtà archiviando i dati sia localmente che nel cloud, contribuendo a soddisfare diverse esigenze di Recovery e conformità.

L’utilizzo di opzioni di archiviazione sia on-premise che nel cloud offre alle organizzazioni un maggiore controllo su dove e come proteggere i dati. Inoltre, garantisce tempi di Recovery più rapidi per i sistemi operativi e facilita la conservazione dei dati a lungo termine.

Il backup nel cloud ibrido is the process of storing backup data in both on-premises infrastructure and cloud storage. This two-tiered approach supports fast local recovery while also providing off-site protection through scalable cloud storage services.

Le aziende scelgono spesso il backup nel cloud ibrido per evitare di affidarsi esclusivamente agli ambienti on-premise o a quelli cloud. I backup locali possono essere utilizzati per ripristini rapidi durante le operazioni quotidiane, mentre i backup nel cloud soddisfano le esigenze di conservazione a lungo termine e garantiscono la diversificazione geografica, contribuendo a ridurre i rischi.

Il modello ibrido offre la flessibilità necessaria per applicare controlli di sicurezza in base al tipo di carico di lavoro e alla posizione. Separando i dati di Recovery dai sistemi di produzione e applicando politiche coerenti, le organizzazioni possono contribuire a ridurre l’esposizione, soddisfacendo al contempo i requisiti operativi e normativi.

Il backup su cloud ibrido offre alle organizzazioni un modo per gestire i dati sia in ambienti locali che nel cloud senza dover fare affidamento su un unico metodo. A differenza dei modelli interamente on-premise o interamente su cloud, le strategie ibride aiutano a soddisfare esigenze specifiche in termini di prestazioni, conformità e controllo dei costi.

An on-premises–only backup setup offers fast recovery for local systems but often requires high capital investment and ongoing maintenance. Cloud-only models reduce infrastructure costs and scale easily, but restoring large datasets can be slower due to bandwidth limits and egress charges. This can impact recovery when working with large files like video repositories or transactional archives.

Alcuni team esitano a optare per lo storage nel cloud pubblico a causa delle preoccupazioni relative ai requisiti normativi e alla dipendenza da un unico fornitore. I modelli ibridi consentono di archiviare i dati in locale quando necessario per la conformità, utilizzando al contempo lo storage nel cloud per carichi di lavoro meno sensibili o per la conservazione a lungo termine. Ciò aiuta le organizzazioni a rispettare le politiche di residenza dei dati, utilizzando al contempo le piattaforme cloud per ridurre i costi di gestione dello storage.

Nel decidere quale soluzione di backup sia più adatta alla propria organizzazione, è necessario tenere conto di una serie di fattori.

Assess workload types. Identify which applications require fast recovery and which can handle longer restore times. Group data based on urgency and business impact.

Review compliance requirements. Map regulatory policies by region or business unit. Use this to decide which data stays on-prem and which can be backed up to cloud storage.

Analyze network capabilities. Measure available bandwidth for daily backups and large-scale recovery. Consider how long it would take to restore critical data from cloud storage.

Model total cost of ownership. Compare on-prem infrastructure costs with cloud expenses like storage tiers, egress fees, and API usage. Include long-term retention requirements.

Define recovery objectives. Set clear RPO and RTO targets for each workload. Design the backup architecture to meet those targets without overcommitting resources.

Use tools that support both environments. Choose platforms that manage data across cloud and on-prem through a unified interface. Look for options that automate backup policies and monitor performance.

Test and validate. Perform recovery tests using both local and cloud backups. Measure restore times and adjust configurations to match business needs.

Identify workloads: Group applications and data by priority, compliance needs, and recovery timelines.

Select storage locations: Choose on-prem storage for local recovery and a trusted cloud provider for offsite retention.

Define retention rules: Set clear timelines for how long to keep local vs. cloud backups.

Configure network settings: Use secure and reliable connections between cloud and on-prem systems.

Apply encryption: Protect data in transit and at rest using standard encryption methods.

Control access: Limit who can modify or recover data using identity-based policies.

Automate backups: Use tools to create automated backup schedules based on workload type or data changes.

Review logs and reports: Use monitoring tools to track backup performance and troubleshoot issues.

Segment by use case: Keep frequently accessed data on-prem and move older or less critical data to cloud storage.

Test recovery regularly: Run restore tests from both cloud and on-prem locations to confirm backup integrity and recovery speed.

Review cost structure quarterly: Track cloud storage usage and adjust data retention policies to avoid unnecessary spend.

Use immutable storage for key workloads: Store sensitive backup data using immutable cloud storage to help reduce the impact of ransomware.

Distribute across regions: Replicate backup data across different geographic cloud regions to reduce risk from localized outages.

L’Illinois State University (ISU) ha modernizzato con successo la propria strategia di protezione dei dati by migrating off-site backup and disaster recovery to AWS. This strategic move allowed the university to decommission its physical off-site data center while maintaining robust protection for critical academic and administrative data.

ISU implemented Commvault Grid to manage its hybrid cloud environment, creating a seamless experience across on-premises and cloud systems. “We chose Commvault Grid because we’ve been very satisfied and comfortable with the Commvault solution,” explained Devin Carlson, Assistant Director of Infrastructure Operations. “We have a lot of confidence and faith in the service.”

The university’s IT team now operates as if everything remains in data centers without changing protection processes or policies. This consistency streamlines operations while adding cloud benefits. Their hybrid approach enables:

Rapid disaster recovery: If a catastrophic event occurs, ISU can shift workloads to Amazon EC2 within minutes, dramatically improving business continuity capabilities.

Flexible storage options: The university backs up on-premises data to tiered AWS storage services (S3, Glacier, and Deep Glacier Archive), optimizing costs based on recovery needs.

Comprehensive protection: The solution extends beyond on-premises backups to protect cloud instances while maintaining existing management practices and SLAs.

Advanced security: Built-in protection against malware and ransomware includes a security dashboard, anomaly detection, advanced reporting, and the ability to manage air-gapped and immutable backup copies.

Craig Jackson, executive director of technology infrastructure & research computing at ISU, highlighted the business continuity benefits: “Commvault Grid and the build-out to the cloud give us some great business continuity and [distaster recovery] planning. If something catastrophic happens, if we need to spin up some [virtual machines] and do restores, now our backups are in the cloud, as opposed to having to move all that data across the wire before making services available.”

Il passaggio a un modello di cloud ibrido ha apportato significativi vantaggi operativi e finanziari all’ISU:

• Reduced administrative overhead by replacing physical maintenance with cloud management.
• Decreased data center footprint with associated power and cooling cost savings.
• Minimized storage requirements through deduplication, resulting in substantial AWS S3 cost savings.
• Enabled self-service access for departments while maintaining central IT control.
• Freed IT resources to focus on strategic initiatives like the Game Design Program and campus research data protection.

As ISU adopts more AWS services, its hybrid cloud backup strategy provides the flexibility to protect new workloads automatically. Jackson summarized the experience: “We’ve been happy with Commvault for so long, it’s kind of expected that the software can do any sort of data manipulation, migration, and protection that we’d need. We’ve never really run into a scenario that Commvault can’t do what we need or ask of it.”

Commvault offers a piattaforma unificata che gestisce la protezione dei dati across on-prem, cloud, and SaaS environments. This gives IT teams a single place to manage backup, recovery, and data movement, reducing the need for multiple tools or manual processes.

L’automazione basata su policy aiuta ad allineare le operazioni di backup alle priorità aziendali. Le organizzazioni possono definire regole per lo spostamento dei dati tra l’archiviazione locale e quella cloud in base alle esigenze di conservazione, all’attività dei carichi di lavoro o ai requisiti normativi. Questo approccio riduce le attività manuali e contribuisce a mantenere la coerenza tra i diversi ambienti.

Commvault offre funzionalità quali il ripristino rapido per i carichi di lavoro critici, l’orchestrazione cloud per il disaster recovery e la deduplicazione per ridurre l’utilizzo dello spazio di archiviazione. Queste funzionalità consentono una risposta più rapida in caso di incidenti, contribuendo al contempo a controllare i costi dell’infrastruttura su larga scala.

Identify workloads: Use Commvault’s tools to discover and classify data across cloud and on-prem systems.

Set protection policies: Define RPOs, RTOs, and retention schedules based on workload type and business impact.

Connect storage targets: Configure on-prem storage systems and cloud services like Azure Blob or AWS S3.

Automate backup schedules: Use policy templates to apply consistent backup timing and retention across systems.

Enable deduplication and encryption: Reduce data volume with deduplication and apply AES-256 encryption for security.

Configure disaster recovery workflows: Set up orchestrated recovery plans for critical workloads in the cloud.

Monitor activity: Use dashboards to track backup success, capacity usage, and restore performance.

Test recoveries: Run scheduled restore tests to confirm data can be recovered within required timeframes.

Commvault supports data protection strategies that align with AWS’ shared responsibility model and other cloud frameworks. Its platform helps reduce complexity while giving organizations flexibility to manage hybrid cloud backup based on their operational and compliance needs.
