First, sorry about the top posting.
Here is the errorlog:

Can't cd to /root: Permission denied
Here is the last few lines of my visudo file:
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:
#includedir /etc/sudoers.d
# Allow backuppc to run tar without a password
backuppc ALL=NOPASSWD: /bin/tar
I searched thru /var/log/kern.log, /var/log/dmesg, /var/log/lastlog, and others
and the only reference I could find was in /var/log/auth.log.
And near the end of "tail -f /var/log/auth.log" is:
Jul 20 06:33:23 dtback01 sudo: root : TTY=pts/1 ; PWD=/root ; USER=backuppc ;
COMMAND=/usr/share/backuppc/bin/BackupPC_dump -v -f localhost
Jul 20 06:33:23 dtback01 sudo: pam_unix(sudo:session): session opened for user
backuppc by root(uid=0)
Jul 20 06:33:31 dtback01 sudo: pam_unix(sudo:session): session closed for user
backuppc
I used this same setup versions ago and it worked (Backuppc 3.3.0 on U13.10, I
think) could this be apparmor blocking it somehow?
As I have not setup ufw, yet, I know it is not the firewall (this box is behind
a hardware firewall so it is safe.)
Could it be selinux blocking something?
The apparmor and selinux are two programs I see many different tutorials being
disabled for various reasons, that is why I suggest these as possibilities.
As everyone can see I am using tar for my localhost backup . . . but that
doesn't mean I am not open to suggestions.
And finally, sorry about the "scratching my head" humor.
Bob.

It is. farragut is my backuppc host.
Is there anything of interest in the logs, specifically the error log?
And do you have your sudoers set up properly?

Thanks for the response, Brad.
I need to clarify that I can backup other hosts just NOT the localhost and I am
confused as to why I cannot.
I see, by your "backup command" that your using rsync. Is this the command to
backup your localhost?
I just tried ssh-ing into the locahost (first time I can remember that
experience) and it worked.
Re-ran my test command "sudo -u backuppc /usr/share/backuppc/bin/BackupPC_dump
-v -f localhost" and got the same "Backup aborted (No files dumped for share
/)" and "Can't cd to /root: Permission denied".
Scratching my head! What is it?

Not sure if scratching your head is helping.... otherwise you might consider
sending the complete output from your debug commands to the list, then if
nothing else, we can scratch our heads while looking at the same cryptic
details.
You might also want to check /var/log to see what information is logged there
Generally, you can simply configure the localhost backup indentically to any
other machine, the only difference is the name of the machine. Personally, I
always use rsync over ssh.
Finally, a copy of the relevant configuration would also be useful...

Adam
