Kopia review
A flexible file-backup tool for technical users who want control over storage and encryption.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kopia is an open-source backup and restore tool for individuals, administrators, and organizations that need encrypted snapshots of selected files and directories. It provides command-line and graphical interfaces for Windows, macOS, and Linux, with web, API, and self-hosted options also supported. The product focuses on file backup: users can create snapshots, mount them, and restore selected files rather than working with whole-machine images. Configurable policies and scheduling support recurring backups, while compression, deduplication, retention, and user-controlled encryption keys help shape how repositories are managed.
The storage ecosystem is a major part of Kopia's fit. Repositories can be local, network-based, remote, or cloud-hosted, with integrations including Amazon S3, S3-compatible storage, Azure Blob Storage, Backblaze B2, Google Cloud Storage, Google Drive, WebDAV, SFTP, and Rclone. This gives technical teams flexibility to align backup destinations with existing infrastructure. Kopia does not provide cloud storage, so users provision and pay storage providers separately. Optional server mode with API support adds a path toward centralized management, while restricted credentials and object locking support ransomware-oriented protection.
Kopia is most compelling when control, portability, and encrypted file snapshots matter more than a simplified, fully managed backup experience. Backup consistency verification and automatic repository maintenance add operational safeguards, and selective restoration keeps recovery focused on individual files or directories. The trade-off is scope: organizations seeking whole-machine imaging should choose a product built for that purpose instead. Kopia is also better suited to users comfortable selecting repositories, configuring policies, and managing storage accounts. For technical users across Windows, macOS, and Linux, its open-source model and repository flexibility make it a focused option for file-level backup.
