The short version

  • Only Trilio has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arcserve UDP multiple security vulnerabilities documented in 2025-2026 including authentication bypass and buffer overflow issues; Trilio coverage is deliberately narrow, so a mixed estate with VMware and physical servers needs a second backup product and two sets of restore procedures.
  • They diverge on capability: Arcserve UDP covers Assured recovery testing, Trilio covers OpenStack backup.
  • Prices and features above were last checked on 1 September 2026.

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

Trilio

  • Coverage is deliberately narrow, so a mixed estate with VMware and physical servers needs a second backup product and two sets of restore procedures.
  • Trilio is a small vendor next to the backup incumbents, and buyers with ten year retention obligations should assess the risk of the company being acquired or wound down.
  • Enterprise pricing is per node or per virtual machine and is not published, which makes it hard to compare against per-terabyte competitors without going through sales.
  • The free basic edition stops at ten nodes with community support only, so the step from evaluation to production is a full commercial negotiation rather than a tier upgrade.
  • Restore performance depends on the object storage or NFS target you supply, and egress charges from a cloud object store during a large recovery sit outside the vendor quote entirely.
