A system and method of error recovery for backup applications that utilizes error recovery logic provided in the storage controller itself are provided. With the system and method, error recovery logic is provided in the storage controller for generating and maintaining error recovery logs for one or more backup operations of one or more backup applications running on one or more host systems. The backup applications may utilize an established set of commands / API function calls to invoke the error recovery logic on the storage controller. At the initiation of the backup operation, the storage controller assigns a unique identifier to the backup operation and returns this identifier to the backup application. The backup application may then use this identifier to initiate error recovery operations or commit changes made during the backup operation via the storage controller. Thus, the storage controller offloads the burden of error recovery from the backup applications.

The present invention provides a method and system for use by software program developers. More specifically, the invention involves a system and method that allows software developers to more effectively diagnose bugs existing in software programs that may result in a crash of the program. Using this method, a software developer will author program code that includes LogEvent calls, which indicate events taking place that are to be logged. The developer will include in the LogEvent call a text string that is meaningful to the software developer and that indicates what the program is doing at a certain event. A generation tool inserts event tags that correspond to the text string and creates an index file mapping the text strings to the appropriate event tags. The text strings are then removed from the program code prior to retail sale, leaving the event tags in place. As the program runs, a log file is created of the events as indicated by the event tags. If the program should crash, the log file is closed and is sent to the software company. In one embodiment, the developer may include a flag that is used to remove any sensitive or personal information prior to the log file being sent to the software company. Once at the software company, the log file is processed to generate a text file by mapping the event tags with the previously removed text strings. Using this text file, the software developer can determine the events leading up to the crash of the program and can more easily develop a solution to the crash.
