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.

An improvement for a self-balancing shielded bipolar ionizer (U.S. Pat. No. 6,002,573), which uses pressurized air or nitrogen to increase performance, extend the operating distance range, and reduce cleaning frequency. An air assist assembly is inserted into the ion generation cavity, which directs pressurized air or nitrogen past the electrodes. In applications where little natural airflow exists, air assist technology is particularly useful. Ions are blown toward the target. This directs the ions to where they are needed, and delivers ions faster. Useful operating distances are increased. Faster delivery minimizes ion losses due to recombination. Furthermore, pure pressurized air protects the electrodes from impurities in the environmental air. Less chemical growth affects electrode performance. Hence, the ionizer exhibits more stable performance, plus the need for electrode cleaning is minimized.
