What SNB supports now—and what comes next.

Back up what matters

Protect chosen folders without treating SNB as a full-system imaging tool.

• Protect multiple folders on local, external, or mounted storage.
• Run scheduled or on-demand backups.
• Configure exclusions, retention, and post-backup verification.
• Continue protection in the background after closing the window.

Protect remote Macs

Install a visible, outbound-only Agent on every Apple Silicon Mac you want to protect.

• Choose folders, schedules, exclusions, bandwidth limits, and network rules.
• Follow preparation, transfer, verification, and total backup time.
• Validate, start, stop, and update Agents from Fleet.
• Close the Agent window without stopping its background engine.

Know what is Recovery Ready

SNB separates a completed attempt from a recovery point that the target has actually verified.

• Only a non-empty, zero-error point verified by the target is labeled Recovery Ready.
• Missing, altered, incomplete, or unexpected data fails safely.
• Browse recovery points and selectively restore files or folders.
• Backup duration is useful status information, but never substitutes for recovery verification.

Transfer less data securely

Reduce repeat transfers while keeping plaintext on the source and target Macs you control.

• Reuse unchanged data between backups.
• Compress data only when compression provides a benefit.
• Encrypt backup content on the source Mac before transfer.
• Resume eligible interrupted preparation only after retained data is rechecked.

Manage every Mac clearly

Use one focused view to understand Agent health, backup work, and update state.

• See online state, last contact, version, folder access, backup status, and recovery readiness.
• Search and filter Agents, then open one focused Agent panel.
• Install service-listed signed updates and confirm the restarted Agent's actual version.
• Keep delayed or failed command evidence visible instead of hiding it behind a healthy heartbeat.

Keep control on the target

The central service connects authorized devices; it is not the backup repository.

• The service is designed not to receive plaintext backup content, paths, or decryption keys.
• Remote Agents cannot delete recovery data or control retention.
• The target verifies a complete point before publishing it to recovery history.
• Packages, release catalogs, and updates are signed and verified before installation.

Platform and recovery limits

• No Intel Mac, Windows, Linux, mobile, or NAS Agent.
• No bootable clone, bare-metal restore, or macOS system recovery.
• No application-consistent guarantee for active databases or virtual machines.
• No ransomware detection or immutable-storage guarantee.
• No stable-release durability, uptime, or data-recovery guarantee.

Operational limits

• The target Mac must remain online with adequate destination storage.
• The first 0.4 Agent installation requires administrator approval; later verified Agent updates can use the restricted updater.
• Full Disk Access still requires one local user approval or an administrator-deployed MDM PPPC profile.
• Remote schedules run in a logged-in macOS user session; logged-out system-level scheduling is not available yet.
• Do not install an Agent update during an active backup. Wait for completion or stop the backup first.
• Recovery evidence is tracked per configured source; aggregate cross-source history, audit export, alerting, and revocation controls are not available yet.
• Mounted-destination replication is available; unattended cloud replication and disaster recovery remain beta roadmap work.
• High availability for the target Mac and central service is not supported yet.
• Verifying one very large recovery point can delay another Agent long enough for that backup to time out. Existing recovery points remain intact; avoid overlapping large jobs and retry any failed run.
• Large-folder and multi-Mac physical acceptance now includes a verified 426,699-file recovery point; broader packet-loss, storage-pressure, and long-duration stress testing remains beta work.
