Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Arcserve UDP

  • Multiple security vulnerabilities documented in 2025-2026 including authentication bypass and buffer overflow issues
  • Slow restore speeds for large backup tasks and recovery operations
  • Requires full backup when changing drive sizes, causing extended backup windows

Lambda

  • No free tier or trial, requiring immediate commitment for testing
  • Single-tenant Superclusters require custom pricing discussions
  • Pricing complexity across multiple GPU types and cluster sizes
  • Less suitable for experimentation or small teams with tight budgets

Answered from the vendors’ own pages

Arcserve UDP: What licensing model does Arcserve UDP use?

Arcserve UDP uses a capacity-based subscription model (Managed Capacity Program) where you license based on total front-end terabytes of protected data rather than per-device. Available in Standard, Advanced, and Premium editions.

Source
Lambda: What makes Lambda's infrastructure different?

Lambda offers single-tenant Superclusters with exclusive GPU access, liquid cooling, and NVIDIA Quantum-2 InfiniBand networking. The company is 100% focused on AI infrastructure with co-engineering support from teams who built infrastructure for major AI labs.

Source
Arcserve UDP: Does Arcserve UDP support cloud backup?

Yes. Arcserve UDP integrates with multiple cloud providers including AWS, Microsoft Azure, Google Cloud, and Wasabi for offsite backup and disaster recovery storage.

Source
Lambda: How does pricing work for large clusters?

1-Click Clusters pricing ranges from $5.54-$9.86 per GPU/hour depending on GPU type and cluster size, with volume discounts for 256+ GPUs. Reserved capacity is available at custom pricing for 1-year+ commitments.

Source
Arcserve UDP: What hypervisors does Arcserve UDP support?

Arcserve UDP supports multiple hypervisors including VMware vSphere, Microsoft Hyper-V, KVM, and others, allowing granular recovery at the VM level with instant boot capabilities.
