Abstract
A source volume is restored to the time of a selected incremental backup volume without writing over all of the data blocks in the source volume. If the source volume has valid data blocks and there are valid records of the changes to these valid data blocks and the valid records are consistent with the state of the source volume and indicate that certain valid data blocks did not change since the selected incremental backup, then the restoration does not write over the valid data blocks that did not change since the selected incremental backup. Otherwise, data blocks are recovered from the selected incremental backup and one or more backups prior to the selected incremental backup. For example, data blocks are recovered by scanning incremental backups in reverse chronological order to find the most recent version of the block in these backups.
