About:
KopiaUI is a graphical user interface for Kopia, a fast and secure open-source backup tool. It enables encrypted, deduplicated, and compressed backups to various cloud storage and local targets. The tool provides robust data protection with policy-based snapshots and efficient storage usage.
Key Features:
  • Cross-platform (Windows, macOS, Linux)
  • End-to-end encryption with AES-256-GCM
  • Deduplication and compression for storage efficiency
  • Support for multiple storage backends (S3, Azure, GCS, local, etc.)
  • Incremental snapshots and policy-based automation
Use Cases:
  • Encrypted offsite backups to cloud storage
  • Local network or NAS backups for home servers
  • Developer workstation snapshots with minimal storage overhead
Alternatives:
  • restic – Similar deduplicated, encrypted backups; restic is CLI-only with a broader backend ecosystem.
  • Duplicati – GUI-focused backup with similar backends; historically less stable than Kopia.
  • BorgBackup – Strong deduplication and encryption; primarily Linux-focused and CLI-based.
