Abstract
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.
