About kopia
Kopia is a cross-platform backup tool designed for Windows, macOS, and Linux. It enables users to create encrypted snapshots of their data, which can be stored locally, on network-attached storage, or in cloud services. The tool focuses on backing up specific files and directories rather than creating full machine images.
Kopia offers both a command-line interface (CLI) and a graphical user interface (GUI), catering to both advanced and regular users. It supports incremental backups, client-side end-to-end encryption, compression, and data deduplication to optimize storage efficiency.
The tool integrates with various cloud storage providers, including Amazon S3, Azure Blob Storage, Backblaze B2, and Google Cloud Storage. Users can also set up their own Kopia Repository Server for custom storage solutions.
