Hi, A scheduled back up is failing which has worked in the past. It completes
when i manually run it in the mornings but fails as a scheduled task. It
appears to start, Any ideas?

Here is the back up report:

The account you use appears to have insufficient access to parts
of drive C:. Unless you supply the full backup command line, it
is difficult to say anything else.

thanks for your time, i will post the script later. Here is the report from
today, it ran ok? It seems to run ok sometimes, very strange and makes no
sense to me.
