Method and apparatus for monitoring the storage of data in a computer system

摘要

One aspect is directed to a method for storing, in a persistent manner, a state of the storage process such that the state of the storage operation may be recovered if the storage operation is interrupted. Another aspect is directed to a method and apparatus that stores the state of a storage operation in a non-volatile memory of a computer that stores data on a storage system. Another aspect is directed to a method for recovering the state of the storage process without having to re-perform storage operations. Another aspect is directed to maintaining state information for other purposes such as monitoring access to data storage locations.
