Best cloud backup tools for compliance and security: Quick comparison
Why do compliance and security teams need the right cloud backup tool?
Compliance and security teams need more than backup storage. They need proof, control, and fast access to the right data when audits, threats, or legal requests hit.
Compliance gaps create the first problem
Many backup tools store data without enforcing the right retention rules. Teams take on risk when they cannot show what they kept, when they kept it, and how they protected it.
Access tracking creates the next problem
Security teams need a clear record of every action on backup data. Missing logs and weak visibility make audits harder and investigations slower.
Backup evidence creates another issue
Some tools can restore data, but cannot prove what existed at a specific point in time. Audits, legal reviews, and incident response all get harder when backup records do not hold up.
Operational overhead adds one more pain point
Complex backup tools create more work for already stretched teams. Security and compliance leaders need strong controls without adding more systems, more manual work, or more ways to screw it up.

1. Eon: Best for multi‑cloud compliance and evidentiary recovery
What it does: Eon uses Cloud Backup Posture Management (CBPM) to autonomously discover, classify, and protect data across AWS, Azure, and Google Cloud, then enforce backup and recovery policies across accounts and regions without agents or manual configuration.
Best for: Enterprises that need audit-ready, ransomware-resilient backups across multiple clouds with strict recovery, retention, and reporting requirements.
Eon auto-discovers unprotected data across AWS, Azure, and Google Cloud, classifies it by resource type and compliance relevance, and enforces backup policies that traditional tools miss or leave to manual tagging. Customers also reduce cloud backup costs by more than 40% and improve recovery times by up to 90%.
Key features
- Autonomously discovers data and backups across accounts, regions, and clouds, then flags unprotected or misclassified assets without relying on tagging.
- Enforces retention policies across connected cloud environments and accounts from a centralized console.
- Preserves logically air-gapped, immutable backups while supporting compliance with privacy and data deletion rules.
- Stores backups in a logically air-gapped, immutable format and keeps them searchable and queryable for audits, investigations, and ransomware recovery drills.
- Let's teams answer who held specific data on specific dates under real‑time pressure.
- Makes it easier to prove which backups existed, who accessed them, and how recovery occurred.
- Restores at the file, table, or record level from the air-gapped vault, enabling teams to recover specific data without a full-system rollback during audits, DSARs, or incident response.
- Detects ransomware across VMs, managed databases, and object storage using multi-signal analysis, then identifies the last clean recovery point for precision restore.
- Holds SOC 2 Type 2, SOC 3, and ISO 27001 (among many more) certifications for its platform and controls.
- Supports HIPAA BAAs, GDPR SCCs, CCPA DPAs, and DORA documentation for regulated customers.
What users say
“Eon made it easy to get everything protected.” Alejandro Zuniga, Eon customer
Pricing
Eon's pricing tracks backup storage consumption and data transfer, so costs follow actual protected data. Billing is metered hourly, and charges only accrue when backups run.
Bottom line
Eon belongs on the shortlist for teams that need to pass audits and recover fast. Multi-cloud organizations with strict regulatory or cyber insurance requirements get clear backup evidence rather than guesswork.
2. Cohesity
What it does: Cohesity delivers data security and management across on-prem and cloud environments, with robust ransomware protection and analytics.
Best for: Enterprises that still run major on-prem workloads and need modern protection with unified visibility across environments.
Cohesity covers VMware, databases, and cloud backups on a single platform. It also detects unusual backup activity that may point to ransomware. Compliance-focused buyers may want stronger reporting and less setup work.
Key features
- Cohesity offers immutable backup storage, but isolated recovery options and deeper detection workflows may require additional licensing and operational setup, depending on the environment.
- AI-driven analytics scan backup data for anomalies and indicators of compromise to flag ransomware and insider abuse early.
- Cohesity IT Analytics gives real-time visibility into coverage, retention, and SLA adherence, with ready-made dashboards for audits.
- The platform protects on-prem, SaaS, and cloud-native sources and offers FedRAMP Moderate authorization for many government workloads.
- Cloud deployments rely on customer-managed clusters and supporting infrastructure, which adds operational overhead as coverage grows.
What users say
Pro: “All in one backup solution.” — Ben S., G2 Review
Con: “Fundamentals don’t work properly from the UI.” Verified User in Banking, G2 Review
Pricing
Bottom line
Choose Cohesity when legacy infrastructure still drives most of your backup risk. Choose Eon when cloud compliance, retention enforcement, and audit readiness matter more.
3. AWS Backup
What it does: AWS Backup centralizes backups for AWS services with policy‑driven plans, retention, and cross‑region copies.
Best for: Large AWS environments that want native integration and are ready to invest internal time in correct design and monitoring.
AWS Backup is well-suited to teams that run entirely in AWS and invest in strong tagging discipline, recovery testing, and per-service configuration. Miss those basics, and coverage gaps, audit evidence, and restore confidence can break down fast. At enterprise scale, service-by-service limitations make it harder to maintain consistent coverage across accounts and regions.
Key features
- AWS Backup lets teams define backup policies and apply them across accounts and regions with automated retention and scheduling.
- Ransomware protection depends on separately licensed features like GuardDuty Malware Protection, with coverage limits that vary by workload and configuration.
- The service protects RDS, DynamoDB, EBS, EFS, EC2, and other AWS resources, supporting a unified AWS-only strategy.
- AWS Backup supports alignment with HIPAA, FINRA, SOC 2, GDPR, FedRAMP, and ISO 27001 when teams configure policies correctly.
What users say
Pro: “Great integration with all my hardware, firewall, and backup software.” Mohammed N., G2
Con: “Managing backups with multiple rules and resources is complex.” Verified User, TrustRadius
Pricing
Bottom line
Choose AWS Backup when AWS is your whole environment, and your DevOps group keeps backup operations tight. Choose Eon when you need better proof, better automation, and better control across multiple clouds.
4. Commvault
What it does: Commvault protects data across cloud, on-prem, and hybrid environments. It also supports backup, recovery, cyber recovery, and ransomware defense in one broad platform.
Best for: Large enterprises that need wide coverage across many systems and want strong governance, retention, and recovery options in one platform.
Commvault is a good fit for buyers who want broad coverage across large estates. It covers a lot, but that breadth can also make the platform feel heavier to run than cloud-first tools. Teams that want simple cloud compliance workflows may find them more complex than they need to be.
Key features
- Protects workloads across public cloud, on-prem, and hybrid environments.
- Includes cyber recovery features such as isolated recovery, immutable storage, and cleanroom recovery.
- Offers flexible storage choices and SaaS delivery options for some use cases.
- Many cloud deployments rely on customer-managed software packages and compute resources that teams deploy, patch, and manage, adding operational overhead as cloud estates grow.
- Depending on the workload, recovery can follow an all-or-nothing approach or require customer-managed compute for granular restore.
What users say
Pro: “I like that Commvault Cloud offers encrypted backup copies and WORM-based compliance lock, which makes the backups extremely secure.” Mahesh K., G2
Con: “We very much regret this purchase.” Verified User, G2
Pricing
Bottom line
Commvault works best in large, mixed environments with complex backup needs. Cloud-first buyers may find it heavier and more involved than they want.
5. Rubrik
What it does: Rubrik protects cloud, virtual, and physical data with automated backup and recovery. It focuses heavily on cyber resilience, ransomware recovery, and fast restores.
Best for: Security-focused enterprises that want strong ransomware defense, centralized policy control, and fast recovery across large environments.
Rubrik is well-known for cyber recovery and centralized control. But cloud deployments introduce customer-managed infrastructure (including EKS-based Exocompute for AWS), and advanced scanning features can require additional licensed components and customer-side compute. Teams focused on cloud compliance workflows may find the operating model heavier than expected.
Teams that care most about audit evidence and retention enforcement across clouds may want more than just recovery strength.
Key features
- Uses immutable backups to support ransomware recovery.
- Protects data across cloud, virtual, and physical environments, though cloud protection can rely on agent-based and compute-based (Exocompute) approaches that add operational overhead as environments scale.
- Offers isolated, off-site backup options, such as Cloud Vault, for cyber recovery.
- Recovery workflows tend toward full-resource restores. Granular file-level recovery for AWS depends on Exocompute (EKS-based compute in the customer environment), which adds Kubernetes and networking overhead.
What users say
Pro: “Rubrik is the primary backup product we use.” Burhan Shakil, TrustRadius
Con: “I’d like to see the product go further than its current feature set. More capabilities, especially stronger analytics, would make it more useful and expand its overall value.” Prem S., G2
Pricing
Bottom line
Rubrik fits enterprises where ransomware recovery and centralized control lead the buying decision. Cloud-first teams focused on compliance workflows, granular recovery, and backup data access may find the operating model and infrastructure requirements heavier than they want.
Final verdict
The right tool depends on your environment and what's driving the decision. Here's how we'd break it down:
- Eon is the pick for multi-cloud teams that need audit-ready backups with teeth: autonomous CBPM, retention enforcement, granular recovery, and searchable evidence across AWS, Azure, and Google Cloud
- Cohesity fits when on-prem and hybrid estates drive the conversation, and teams can manage customer-deployed clusters
- AWS Backup works if your environment is entirely AWS and your team is disciplined about tagging and testing
- Commvault suits large enterprises with broad coverage needs across complex, mixed estates
- Rubrik fits when ransomware recovery and centralized control lead the decision, and teams can absorb the customer-managed infrastructure in the cloud
If compliance has to be built into how backup works, not bolted on after the fact, Eon is where we'd start.
