Abstract:
A method of storing a file in memory so that the file can be recovered in the event of a memory failure is provided. A block of memory having a first predetermined memory size is allocated at a first device. A first header is defined that includes an identifier of a first file and a sequence value. The defined first header is written to the allocated block of memory, and a first cluster of the first file is written to the allocated block of memory. The first cluster has a second memory size that is smaller than the first predetermined memory size. The sequence value is updated, and a next cluster of the first file is identified. The process is repeated with the next cluster as the first cluster and with the updated sequence value as the sequence value until the first file has been written to the allocated block of memory.
