Arcserve UDP vs Datto SIRIS Comparison: Reviews, Features, Pricing & Alternatives in 2026

Arcserve UDP (Unified Data Protection) gives you a single interface to manage the backup and recovery of your entire IT environment. You can protect physical Windows and Linux servers, virtual machines on VMware or Hyper-V, and cloud data within Microsoft 365 or AWS. It eliminates the need for multiple point solutions by combining enterprise-grade backup with high availability and disaster recovery capabilities.

You can significantly reduce your storage footprint using its global source-side deduplication, which only saves changed data blocks across all your nodes. The platform is designed for mid-market and enterprise IT teams who need to meet strict recovery time objectives (RTOs) and recovery point objectives (RPOs). Whether you are recovering a single file or performing a bare-metal restore of an entire server, you can manage the process from one central console.

Datto SIRIS provides you with a unified business continuity and disaster recovery platform designed to protect physical, virtual, and cloud environments. You can eliminate downtime by booting up servers locally or in the secure Datto Cloud in seconds, ensuring your operations continue even during a total hardware failure. The system automatically verifies every backup with screenshot verification, so you never have to wonder if your data is actually recoverable when a crisis hits.

You can manage your entire fleet of protected devices through a single cloud-based dashboard, making it ideal for managed service providers or IT teams overseeing multiple locations. The platform also includes built-in ransomware detection that alerts you the moment it spots suspicious file patterns, allowing you to roll back to a clean state before the infection spreads. It simplifies complex recovery tasks into a few clicks, giving you peace of mind that your business stays resilient.
