摘要： One method of redirecting an in-process backup operation to a new storage device involves receiving a request to perform a backup from a backup application. In response to reception of the request, the method causes backup information generated by the backup application to be stored on a first storage device. The first storage device is monitored in order to detect how much free space is available. If the amount of space available on the first storage device drops below a threshold amount prior to completion of the backup, the backup is redirected by causing any subsequent backup information generated by the backup application to be stored on a second storage device. Metadata associated with the backup identifies that information associated with the backup is stored on both the first storage device and the second storage device.
