What Seyvd does.

The parts that already work in the current development build.

Your storage, encrypted

Back up to S3-compatible services, network storage or a local folder. AES-256-GCM encryption runs before data leaves your Mac.

Only changed data moves

Chunk-level deduplication and LZ4 compression reduce repeat uploads, including when a file moves or changes name.

Restore what you need

Browse timestamped backups, search the file tree and restore selected files or folders to the original location or somewhere new.

Know the backup can help

Health checks cover freshness, restorable snapshots, sampled content, encryption recovery and the active schedule.

Encrypted Mac backups.

Seyvd encrypts backups on your Mac with AES-256-GCM before uploading to S3-compatible cloud storage. Your provider receives encrypted content.

Scheduled cloud backups.

Seyvd runs scheduled incremental backups to S3-compatible cloud storage with deduplication and bandwidth controls on Mac.

Readable files stay on your Mac.

Seyvd stores credentials in Keychain and encrypts backup contents locally. Your storage provider receives encrypted chunks, not readable documents.

Common Seyvd questions.

Where can Seyvd store backups?

The current build supports S3-compatible services and local folders, including external drives and mounted network shares.

Can HK Softworks read my files?

No. Seyvd encrypts files on your Mac and does not send them through an HK Softworks account or service.

What happens if I lose the encryption password?

The Recovery Kit provides a separate recovery path. Save or print it after the first backup and keep it away from the Mac being protected.

Is Seyvd available now?

Not publicly. Seyvd remains in active development and is not listed on the Mac App Store.
