Can you run the backup against the host of the NFS drive instead of another host mounting it over the network? The way rsync works is that the host where it runs has to read the whole contents of each file in order to use the block checksum algorithm to decide what differences to send. If the drive is mounted over NFS, that complete read will be over a network before it can decide how to reduce network use sending to the rsync partner. -- 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/
