Kopia

Kopia — backups without the drama There’s a certain kind of backup tool that tries to be everything at once, and usually ends up being a headache. Kopia isn’t like that. It’s small, open source, runs on Linux, Windows, macOS — and doesn’t care if the storage is a USB drive on your desk or a bucket in S3.

It works with a repository model: snapshots go into a single structured store, no matter where it’s hosted. Files are split into chunks, duplicates removed, compressed with zstd, then encrypted

Kopia — backups without the drama

There’s a certain kind of backup tool that tries to be everything at once, and usually ends up being a headache. Kopia isn’t like that. It’s small, open source, runs on Linux, Windows, macOS — and doesn’t care if the storage is a USB drive on your desk or a bucket in S3.

It works with a repository model: snapshots go into a single structured store, no matter where it’s hosted. Files are split into chunks, duplicates removed, compressed with zstd, then encrypted before leaving the client. That encryption isn’t just for show — every piece is verified, so corruption gets spotted early.

For small setups, it’s a one-line CLI backup. For bigger ones, server mode adds a web UI for browsing snapshots, setting schedules, and managing retention. It’s not fancy, but it’s reliable.

Capabilities

Feature Description
Cross-Platform Runs on Linux, Windows, and macOS with identical core features
Storage Flexibility Local disks, NAS, SMB shares, S3-compatible services, Google Cloud, Azure Blob, Backblaze B2
Deduplication Content-defined chunking eliminates duplicate data storage
Compression High-speed zstd compression for reduced footprint
End-to-End Encryption Client-side encryption with integrity verification
Policy Control Per-path scheduling, retention, and compression rules
Server Mode Web UI for multi-client management and monitoring
Open Repository Format Can be reconnected from any authorized client without lock-in

Deployment Notes

– First large backups are best seeded locally before syncing to remote storage.
– Repository format is portable and not tied to one machine.
– Works equally well in offline and cloud scenarios.
– In low-bandwidth environments, deduplication drastically shortens backup windows.
– Authentication and access rules apply in server mode.

Quick Start (Linux)

curl -LO https://github.com/kopia/kopia/releases/latest/download/kopia-linux-x64.tar.gz
tar -xzf kopia-linux-x64.tar.gz
sudo mv kopia /usr/local/bin/

kopia repository create filesystem –path /srv/kopia-repo
kopia snapshot create /home/user
kopia snapshot restore /restore/path

Usage Scenarios

– Nightly workstation backups to NAS without agents.
– Cloud archiving of project data with encryption and deduplication.
– Rolling snapshots for application servers with quick restore needs.
– Mixed-OS fleet backups under one unified system.
– Low-bandwidth site backups with minimal data transfer.

Understanding Incremental Backup

What is Incremental Backup?

Incremental backup is a method of data protection where only the changes made to the data since the last backup are saved. This approach is more efficient than full backups as it reduces the amount of data that needs to be transferred and stored, making it ideal for large datasets and environments where data changes frequently.
