You learn that in a previous security breach at GearUp, a disgruntled employee destroyed the encryption key that had been used to protect data. How will you prevent a similar data safeguard problem at GearOn

The data can be safeguarded using key escrow procedure.

Explanation:

Key escrow basically means to store the cryptographic key in an "escrow" by a reputable trusted third party. The copy of the encryption key is kept with the third party. In case the cryptographic key gets lost or destroyed, then the key escrow service helps to access the encrypted data. It also manages the access control to the key in case the key gets lost. So this way in case of security breach at GearOn the key escrow service can be used to re-implement or access the key easily.
