Abstract
In one example of a backup method, a backup process is started but experiences a failure prior to completion of the backup such that only a first portion of the set of data is backed up prior to the failure. A failed saveset associated with a second portion of the set of data is discarded, and a retry started. The retry includes performing an incremental backup of the first portion of the set of data and performing either a full or incremental backup of the second portion of the data. Upon successful completion of the retry, the incremental backup of the first portion of the set of data is combined with the backup of the second portion of the set of data to create a restore saveset. The restore saveset is used to create a full backup image that includes a full backup of the set of data.
