Would appending the file size to the md5 (either literally or notionally) further decrease the astronomically small chance of a non-purposely constructed collision? If so would that be helpful? (not size is easily available without additional computation) Also, you note a number of features that should significantly speed up backups (including rsync 30, c-code, --checksum flag, etc.). Have you done any benchmarking relative to v3.x? Again, sounds like an incredible step forward. I hope that your new job allows you some spare time to take this through to final release! (and good luck btw on your new job!) ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ BackupPC-devel mailing list BackupPC-devel@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-devel Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
