Never Lose a Byte

Deduplicating, encrypted, cross-platform backup with a desktop app.

Download optim-backup CLI or desktop app. Single binary, zero dependencies.

Point to your S3 storage. Set encryption key. Choose paths and schedule.

Scheduled backups run in the background. Only changed chunks are uploaded. Old snapshots pruned automatically.

Content-defined chunking splits files at natural boundaries. Small changes = small uploads.

2-3x faster than SHA-256. Every chunk content-addressed for cross-snapshot deduplication.

Better ratio than gzip, faster than zlib. Per-chunk compression for optimal dedup.

Authenticated encryption per chunk. Random nonce. Key never leaves your machine.
