Abstract: A method and apparatus of a device that manages a thermal profile of a device by selectively throttling input/output operations of the device is described. In an exemplary embodiment, the device monitors the thermal profile of the device, where the device executes a plurality of processes that utilize storage of the device. In addition, the plurality of processes include a high priority process and a low priority process. If the thermal profile of the device exceeds a thermal threshold, the device decreases a first bandwidth range for the low priority process and maintains a second bandwidth range for the high priority process. The device further processes a storage request of the low priority process using the first bandwidth range and processing a storage request of the high priority process using the second bandwidth range.

Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for wireless data protection utilizing cryptographic key management on a primary device and a backup device. A system encrypts a file with a file key and encrypts the file key twice, resulting in two encrypted file keys. The system encrypts each file key differently and stores a first file key on the primary device and transmits one of the encrypted file keys in addition to the encrypted file to a backup device for storage. On the backup device, the system associates the encrypted file key with a set of backup keys protected by a user password. In one embodiment, the system generates an initialization vector for use in cryptographic operations based on a file key. In another embodiment, the system manages cryptographic keys on a backup device during a user password change.
