Under Development / Private TestingEncrypted archives in your Google Drive. Recovery keys kept separately.
Developed and maintained by CredoNomics Investment Solutions, CardLedger Backup is currently used for controlled development and recovery validation with synthetic data.
How it works
Choose your Google account and the intended backup folder or existing files through Google’s supported authorization and Picker flow.
The utility encrypts the backup archive using AES-256-GCM before cloud transfer. The decryption key stays separate from Google Drive.
Controlled tests read back the encrypted archive and non-secret integrity metadata, authenticate them and restore into an isolated disposable test database.
Security and control
The utility requests only https://www.googleapis.com/auth/drive.file. It works with files created by the app or explicitly selected for it, rather than arbitrary access to your entire Drive.
This scope can permit changes to app-authorized files. The current controlled workflow does not enable remote deletion or retention pruning.
OAuth token records use Windows DPAPI CurrentUser encryption and restricted local permissions. Decryption requires the authorized Windows user profile; tokens are not published on this website.
Backup decryption keys are not uploaded to Google Drive. Keep the recovery key and its unlock information safely and independently; losing the key can prevent recovery.
You can revoke Google authorization through your Google Account connections. Revocation stops future authorized access; existing encrypted archives remain until you separately delete them. The privacy policy explains local tokens, retention and cleanup.
