You have /usr/sbin in your PATH setting twice. Having any directory in PATH more than once will slow down access to any utilities found in any directory after the second occurrence of that directory.

Unless you have some utility that appears in more than one of the directories in PATH, you want the directory that contains the most frequently used utilities first in your PATH and the directory containing the utilities that are the least frequently used last in your PATH. Under usual circumstances, you'll want to put /usr/bin first in PATH (and get rid of one of the /usr/sbin entries and one of the /root/bin entries) like:
Code:
/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/root/bin

Given the naming conventions used on the directories in your PATH, is there also a /root/sbin directory containing utilities that you sometimes want to find? And, as Jim suggested, if your system has /bin and /usr/bin as distinct directories, be sure that both of them are included in PATH.

bup-on

bup-on(1)						      General Commands Manual							 bup-on(1)

NAME

       bup-on - run a bup server locally and client remotely

SYNOPSIS

       bup on <hostname> index ...

       bup on <hostname> save ...

       bup on <hostname> split ...

DESCRIPTION

       bup on  runs  the given bup command on the given host using ssh.  It runs a bup server on the local machine, so that commands like bup save
       on the remote machine can back up to the local machine.	(You don't need to provide a --remote option to bup save  in  order  for  this	to
       work.)

       See bup-index(1), bup-save(1), and so on for details of how each subcommand works.

       This  'reverse  mode'  operation  is  useful when the machine being backed up isn't supposed to be able to ssh into the backup server.  For
       example, your backup server can be hidden behind a one-way firewall on a private or dynamic IP address; using an ssh key, it can be  autho-
       rized  to  ssh  into  each  of your important machines.	After connecting to each destination machine, it initiates a backup, receiving the
       resulting data and storing in its local repository.

       For example, if you run several virtual private Linux machines on a remote hosting provider, you could back them up to a local  (much  less
       expensive) computer in your basement.

EXAMPLES

	      # First index the files on the remote server

	      $ bup on myserver index -vux /etc
	      bup server: reading from stdin.
	      Indexing: 2465, done.
	      bup: merging indexes (186668/186668), done.
	      bup server: done

	      # Now save the files from the remote server to the
	      # local $BUP_DIR

	      $ bup on myserver save -n myserver-backup /etc
	      bup server: reading from stdin.
	      bup server: command: 'list-indexes'
	      PackIdxList: using 7 indexes.
	      Saving: 100.00% (241/241k, 648/648 files), done.
	      bup server: received 55 objects.
	      Indexing objects: 100% (55/55), done.
	      bup server: command: 'quit'
	      bup server: done

	      # Now we can look at the resulting repo on the local
	      # machine

	      $ bup ftp 'cat /myserver-backup/latest/etc/passwd'
	      root:x:0:0:root:/root:/bin/bash
	      daemon:x:1:1:daemon:/usr/sbin:/bin/sh
	      bin:x:2:2:bin:/bin:/bin/sh
	      sys:x:3:3:sys:/dev:/bin/sh
	      sync:x:4:65534:sync:/bin:/bin/sync
	      ...
