Abstract
High performance backup of a computer system includes backing up changed portions of files and selectively choosing files for backup. Files are treated as a collection of blocks, and only those blocks which have changed since a previous backup are transmitted to a backup system. Prior to selecting blocks for backup, files are selectively chosen by excluding previously archived files such as commercial software, and excluding other non-critical applications and data based on, inter alia, commonality, modification date and a list of files which are already present in the backup system. Files may also be pre-loaded into a backup system in anticipation of their presence in the computer system to be backed up.
