If the files are mostly tiny, you can see how rsync's action of exchanging the directory information needed to determine existing/changed status would be almost as much work as updating the files. > If your *second* incremental backup takes almost as long as the full backup, > we'll need more details, as your configuration is deviating significantly > from expectations. I think I recall something about the third rsync backup getting a speedup too, where the block checkums are saved on the 2nd run after a file has been copied. Not sure if that still applies to v4. -- Les Mikesell lesmikes...@gmail.com _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
