Thanks for your suggestions.
Disabling apparmor made no difference.
"sestatus" returns "command not found" and the only other search engine
references I can find about selinux is how to install it on 16.04. And other
references that it been dead since Karmic.
The command sting I am running is from an old (cannot find it on Backuppc
documentation anymore) wiki page I printed years ago. I not sure what you mean
when you asked "What is the current working directory when you ran the above
test?" It was run as sudo by an administrative user on the Backuppc machine.
And, last question, I am not sure what you mean by "by using a locale other
than C" . . . like 'C' the language? How would I " . . . change the OS default
locale to C, and then try it again"? (OS is Ubuntu 16.04)

First, sorry about the top posting.

This seems to be where the problems start, so I suspect it. Most commonly these
type of problems are caused by using a locale other than C, so the first thing
I would try is to change the OS default locale to C, and then try it again.

Here it is again, so looks like it affected the ping command as well as the tar
command above...

This almost looks like it is an error message generated on the local side,
AFTER the backup attempt has completed. What is the current working directory
when you ran the above test? Some other commands encoded into your shell prompt
or similar?
<blockquote>
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.
</blockquote>
I don't know enough about apparmor or selinux, but I'd suggest trying to
disable them as per the online suggestions, and then see if it fails the same.
You can always re-enable these features once you have solved the problem
<blockquote>
As everyone can see I am using tar for my localhost backup . . . but that
doesn't mean I am not open to suggestions.
</blockquote>
Personally, I'd use rsync over SSH, but there is no reason tar should not
work....
<blockquote>
And finally, sorry about the "scratching my head" humor.
</blockquote>
No problem, I was trying to add some also, but I guess my jokes online are as
bad as my jokes in person.....
Let us know how you go, please remember to include config, logs and actual
output of commands run wherever possible, it makes it easier for more people to
help.
PS, don't apologise for top-posting, either don't top post, and make the
time/effort to post properly, or just top-post anyway and recognise that some
people who might be able to assist will not because it is too difficult/time
consuming to try, or just because top posting really annoys them. There is no
point in saying you are sorry for something, and then purposefully doing it
anyway.
Regards,
Adam
