A user enables TPM encryption on their device and sets up a recovery key backup. The system periodically checks the backup and sends a notification when it is near expiration. If the backup fails, the system sends an alarm notification, prompting the user to take action to recover their data.
A Trusted Platform Module (TPM) is a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. In the context of full-disk encryption (BitLocker, for example), the TPM does store your data encryption key directly. Instead, it seals the key within a protective wrapper that requires specific system state measurements (PCRs—Platform Configuration Registers). tpm encryption recovery key backup alarm
The is a warning triggered in VMware vCenter Server (version 7.0 Update 2 and later) when an ESXi host with an active Trusted Platform Module (TPM) 2.0 chip has not had its configuration encryption recovery key manually backed up by an administrator. A user enables TPM encryption on their device
This alarm is designed to prevent total data loss; since now uses the TPM to encrypt its core configuration, losing the TPM chip (e.g., due to a motherboard failure) without a backup key makes the host unbootable and the configuration unrecoverable.

Six months later, a similar TPM failure occurred. The alarm fired at 9:14 PM. The helpdesk pulled the key from AD within 2 minutes. The user entered it, the system booted, and they continued working. Downtime: 4 minutes. Data loss: zero.
