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

Redstor

  • It is sold through the channel, so you cannot buy it direct and your price and support quality depend entirely on the partner you engage.
  • Pricing is not published at all, and because partners resell it with their own margin, comparing quotes across MSPs is comparing partner markups rather than product cost.
  • The InstantData streaming advantage depends on network bandwidth to the data centre, so sites with poor connectivity see much less benefit than the demonstrations suggest.
  • Its footprint is concentrated in the UK, Europe and South Africa, so multinational organisations needing consistent coverage in North America or Asia will find the regional story uneven.
  • Feature depth for large enterprise virtual machine estates trails Veeam and Rubrik, so it fits small and medium client workloads rather than complex data centre recovery.
