Comprehensive Defense Against Ransomware with Arcserve: Your Guide to Immutable Backup Protection

By Thirumeninathan Murugan

Imagine it's 11 p.m. Your phone buzzes with a message from your CEO: "We've been hit by ransomware. Operations are frozen." You immediately try to spin up the backups, but they're encrypted too. Each passing hour brings mounting financial losses, customer frustration, and compliance risks.

This nightmare scenario is progressively more common as ransomware attacks become increasingly sophisticated and targeted, with AI-powered ransomware attacks dubbed “Ransomware 3.0" on the horizon.¹ The statistics are alarming: over 80% of recent ransomware attacks targeted companies with fewer than 1000 employees,² and in 94% of ransomware cases, attackers attempt to compromise backups directly.³

The average cost of recovering from an attack is $1.85 million—excluding potential ransoms.⁴ Can your organization afford that risk?

What Is the Ransomware Gap in Backup Systems? 

Many backup and recovery methods leave organizations vulnerable in several critical ways:

• Targeted Attacks on backup data: the majority of ransomware attacks now specifically target backup data to disable recovery options
• Immutable storage limitations: Existing solutions often sacrifice data efficiency or simplicity
• Fragmented environments: On-premises and cloud storage gaps create vulnerabilities and complexity

Many solutions can no longer meet the challenge. You need a comprehensive, and seamless approach to data protection that ensures recoverability with zero compromise.

Enhanced Protection with UDP 10.2 Integration

The release of Arcserve Unified Data Protection (UDP) 10.2 and new Arcserve Cyber Resilient Storage capabilities help organizations gain control over immutable backup storage both in the cloud and on-premises. These powerful software solutions work together to provide integrated control of immutable storage managed directly from a single, familiar UDP interface.

UDP 10.2 expands capabilities that make managing immutable backups simpler and more effective:

• Manage immutable storage directly from the UDP Console: Gain streamlined control over your immutable backups without switching between multiple management interfaces
• Create and manage data stores in your preferred cloud environment: Whether you use Arcserve Cloud Storage, AWS, Microsoft Azure, or Google Cloud
• Enhance compliance controls to prevent data tampering: With new compliance mode options, snapshot data cannot be changed or deleted by anyone—even users with root privileges
• Expand role-based security to immutable data stores: Clearly separate administrator and non-administrator access to immutable data stores with granular role-based access controls (RBAC)

On-Premises Immutable Backup Protection

For organizations that need to maintain immutable backups on-premises, Arcserve now offers Cyber Resilient Storage as a software appliance that integrates seamlessly with the on-premises UDP Console for comprehensive ransomware protection.

This solution provides:

• Immutable snapshots for business-critical data: Configure snapshot frequency and retention schedules to meet your specific data protection needs
• Flexible implementation on your hardware: Install Arcserve Cyber Resilient Storage on hardware of your choice for implementation flexibility and system integrity
• Seamless management from the Data Resilience Console: Whether you prefer using the UDP on-premises console or UDP Cloud Console
• Software RAID for enhanced fault tolerance: Add an extra layer of resilience with software-based RAID capabilities, even for hardware instances that don't have hardware RAID

Five Steps to Implementing Arcserve Cloud Cyber Resilient Storage

Implementing Arcserve Cloud Cyber Resilient Storage follows a straightforward process that builds robust data protection quickly and efficiently:

1. Select the right storage capacity: Purchase the Arcserve Cloud Cyber Resilient Storage capacity that matches your organization's requirements, available in 1 terabyte increments
2. Activate your Arcserve Cyber Resilient Storage account: For cloud storage, you'll receive an activation email containing login credentials for the Arcserve Cloud Storage portal
3. Configure your Cyber Resilient Datastores: Open the UDP Cloud Console and navigate to the Recovery Point Server (RPS) page to set up your immutable datastores
4. Validate and optimize immutable backup datastore: Once configured, your immutable datastore becomes operational with built-in UDP protections, including impressive deduplication and compression
5. Monitor and restore immutable backups: When needed, UDP simplifies the recovery process by showing you a list of available snapshots for recovery

For Arcserve Cyber Resilient Storage, the on-premises version of Cyber Resilient Storage, the implementation steps are similar, but performed via the on premises UDP Console.

With a well-thought-out immutable snapshot plan that dictates frequent snapshots (e.g., once a day), Arcserve Cloud Storage and UDP can significantly improve Recovery Point Objective (RPO) targets at a low cost.
