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

Borg Backup

  • Linux, macOS and BSD only; Windows is not a supported platform
  • Command-line only, with no graphical interface in the project itself
  • Version 2.0 is still in beta, so production use means staying on the 1.4 line
  • Restoring requires the Borg tooling, since archives are a deduplicated chunk store rather than plain files
