Backup and Recovery

Backup and Recovery

Goals

• Protect users from data loss.
• Ensure backup confidentiality.
• Support deterministic restoration of app state.

Backup Guidance

• Encrypt backups before export.
• Require user-selected passphrase for encryption/decryption.
• Avoid storing backup files in publicly shared or weakly protected locations.

Recovery Guidance

• Validate backup structure before attempting full import.
• Reject backups with invalid format or failed cryptographic checks.
• Show clear user-facing recovery outcomes (success, partial, failure).

Recommended Validation Cases

• Wrong passphrase.
• Corrupted backup content.
• Incompatible schema/version.
• Missing required wallet fields.

Data Hygiene

• Never include private keys or seed phrases in logs.
• Avoid crash reports that contain sensitive cryptographic payloads.
