Zusammenfassung:A method for backup and restore using inconsistent state indicators comprises identifying, from among a plurality of data objects to be backed up, one or more data objects that are in an inconsistent state, and storing inconsistent state indicators (such as modified object attributes) associated with the data objects. The method may further include generating a backup aggregate such as a snapshot of the plurality of data objects, where the backup aggregate includes backup versions of the inconsistent data objects. Prior to restoring one or more data objects from the backup aggregation, the method may include using the inconsistent state indicators to identify the backup versions that correspond to the inconsistent data objects, e.g., to exclude backup versions corresponding to inconsistent data objects from a list of full restoration candidates.
