Abstract
A method, apparatus, and article of manufacture for performing a point-in-time backup using multiple copy technologies includes steps of suspending execution of updates to the source data; determining what point-in-time backup technology is supported by the device by determining the device and extents of the source data; processing each of the extents as determined by the backup technology supported and copying the source data in point-in-time; and backing up copied entire source data to a target media. If the backup process fails, the method, apparatus, and article of manufacture provides a restart function.
