Cloud Backup

Overview

Wallet applications may back up encrypted seeds, key shares, device state, descriptors, or configuration to cloud storage. Remote storage can protect against loss of the local device and make restoration easier across locations.

Security depends on what is encrypted, where encryption occurs, who holds decryption keys, and how the cloud account is recovered. Provider-side encryption does not prevent the provider or a compromised account from accessing plaintext if it also controls the keys. Account takeover, synchronization errors, deletion, and jurisdictional access remain risks.

Sensitive wallet backups should be encrypted before upload with independently protected credentials, use strong account authentication, and avoid exposing a complete spending secret through one cloud identity. Teams should maintain tested recovery options outside the same provider. Convenience improves availability, but cloud storage changes rather than removes backup risk.

Evidence for Cloud Backup should preserve incident time, affected identifiers, last known state, claimant and approver checks, backup or share version, actions performed, credentials revoked, assets verified, discrepancies found, and final owner acceptance. For Cloud Backup, sensitive recovery material must not appear in the incident record.

Cloud Backup differs from ordinary retry or customer support because it restores authority after a control failure. For example, reinstalling an application is not successful recovery until the correct accounts, networks, balances, policies, and transaction history are reproduced and compromised authority can no longer act.

A controlled Cloud Backup process moves through detection, containment, claimant verification, approval, restoration, validation, credential or guardian replacement, reconciliation, and closure. For Cloud Backup, emergency access should be time-limited and should not silently weaken the authorization policy used during normal operation.
