Can anyone let me know how to restart the backup?

TKLBAM is designed by default to resume if it is interrupted and then rerun. But in this instance it appears that a directory that was there last time it was interrupted has since gone...

To make it start clean (when it didn't finish last time) you can use the '--disable-resume' switch (as documented on the tklbam-backup man page).

FWIW you can find man pages for all TKLBAM commands in the docs here.

I tried that option and still get the same response. I can't seem to get it to re-start a brand new backup, even with the --disable-resume switch. Is there some kind of cache or index that was created?

Does the /TKLBAM directory exist? 
ls /TKLBAM
If so you could try manually moving (so TKLBAM can't see it anymore) and see what happens... 
mv /TKLBAM /TKLBAM-old
Then try again... If that works then the old TKLBAM directory can safely be deleted: 
rm -r /TKLBAM-old
Otherwise I'll probably have to get Liraz on the job to have a look...

The backup directory did not exsist. I created it and it is still producing the error. After the backup ends the TKLBAM directory is no longer there. No luck - full output from command.

Ok first thing I'd try next is to see if you are using an old version of TKLBAM (probably should have done this first...) 
apt-get update && apt-get install tklbam tklbam-squid-common tklbam-squid tklbam-python-boto tklbam-duplicity

TBH I'm not sure whether we need to list all the TKLBAM dependancies too but it won't hurt...

If that just says that they are all at the latest version; that's ok. Otherwise let them update and try again (as per above).

If that doesn't make any difference then the next thing that we could try is to exclude that particular path. You can test with this: 

tklbam-backup --simulate -- -/var/spool/postfix/active/

If that works then try running it again without the '--simulate' switch...

FYI the "-- -/path" makes tklbam skip that path (and all the files & directories within it) but only for that session. Permanent overrides are set in /etc/tklbam/overrides
