It's the tar that keeps on failing in the supervise folder on my server. I think it is the two files - 'control' and 'ok' which are giving a permission denied error, so access my whole tar file is then denied. I'm not sure if this stopped working at the same time as when I started to use SVC, my gut feeling is that it did and there was a problem with the backup server at the time of implementation so we didn't realise until now.
I have tried to tar all the files apart from the /etc/ folder for now just to get a working backup and then I will try to chown the supervise folder.
Thanks for the help Jim, much appreciated.
