Restoring of content of data blocks to non-volatile storage as the content existed at a particular instant in time. After accessing the last backup representing the most recent backup of the plurality of data blocks prior to the particular instant in time, the content of each data block represented in the last backup is written to a corresponding position in the non-volatile storage. This last backup may be an incremental backup in which only those data blocks that had changed since the immediate prior backup were actually backed up. Then, restoration occurs through each prior backup in reverse chronologic order until the full backup is encountered and restored. When restoring a backup, a data block is not restored if the data block had already been restored proceeding in reverse chronological order.
