Methods and systems for managing a data processing system are disclosed. The data processing system may provide computer-implemented services and may include in-band hardware resources that operate as specified by operation data of the data processing system while providing the services. However, if the operation data becomes unavailable to the data processing system, then the data processing system may be unable to provide the desired services. Therefore, to increase the likelihood of providing the desired services, the operation data may be managed using distributed backup and recovery processes. To decrease security risk associated with operation data backup and recovery, the distributed processes may be performed using out-of-band components of the data processing system, bypassing in-band hardware components that may be more vulnerable to being compromised (e.g., by a malicious party). The out-of-band management of the operation data may reduce the likelihood of interruptions in providing the desired services.

A memory block recovery process is used to review and recover memory blocks of a memory device that have potentially been misidentified as bad blocks. The memory block recovery process is initiated when a threshold number of entries in a failed memory block list is exceeded. During the memory block recovery process, the failed memory block list is analyzed to determine whether there is any correlation between memory blocks that failed programming operations and memory blocks that were programmed prior to the memory block failing its programming operation. If there is a correlation, an independent program operation is performed on each memory block that failed its programming operation. If the independent programming operation on the memory block is successful, the memory block is reclaimed and the prior programmed memory block is identified as a bad block.
