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

StorageCraft ShadowProtect

  • Host-based backup requires Windows Server 2016 or above on the Hyper-V host, and desktop, client and Pro editions are not supported
  • Host-based and agent-based backup are mutually exclusive installation modes in ShadowProtect 8.0; one machine cannot run both
  • Switching from agent-based to host-based requires a clean reinstall rather than an in-place upgrade
  • Host-based backups are not compatible with VirtualBoot
  • Granular file and folder recovery is not available for host-based backups; the whole backup must be restored to a .vhd or .vhdx first
  • Host-based backup jobs do not report status to ShadowControl
  • Advanced Verification in ImageManager 8.1 is not supported for host-based backups
  • All host-based backups go into a single folder by default, so separating them per VM means creating a separate backup job for each
  • Host-based licence keys are generated only through the Arcserve MSP portal
