Abstract
In one example of a time-based checkpoint restore method, a backup of data is commenced. Prior to completion of the backup, a failure is experienced such that only a portion of the data is backed up. A first partial saveset is created, and time and path checkpoints are identified. The backup is then retried, using the time and path checkpoints. Data backed up prior to failure is incrementally backed up, and the remaining data not already backed up is fully backed up. A second partial saveset of these backups is created and combined with the first partial saveset to create a resultant saveset that can then be used to create a full backup image that includes a full backup of the data.
