Hi Arno - Thanx for the reply.
You raise some interesting points - I will try to further the discussion
while reducing the size of this email.

Firstly, I am not sure what the "No" in your post refers to....
Interesting (I am assuming that you meant "triggered recycling"). Yes,
I will agree that it triggered Recycling - the volume status was "Used"
before I issue the stat command. I think it is indeed the issue - when
the job starts it can't find a suitable volume - though it appears that
the requirements for recycling have been met. Once the stat command
changes the status to Recycle the backup proceeds as desired.

The point I was trying to make is that I expect a stat 4 (one line) to
produce the same output as
stat <enter>
4 <enter>
and it doesn't appear to. Am I incorrect in expecting that the output
should be the same regardless if the stat command is issues on one line
or 2 ?

I heave seen some references to the Admin jobs - in fact I thought that
might be the best way to trigger the recycle - but I have not found much
information on the admin job.

As my setup - daily volume changes in separate pools - is the only one I
have experience with I can't really comment on the relative amount of
work required to make it work :). I do know however that this type of
backup scenario is a very good fit for smaller businesses who understand
the importance of backups (plenty of small businesses - as well as home
users - DON"T understand that backups could be crucial to their
existence). Smaller companies are also more likely to not opt for an
autochanger solution - cost reasons perhaps - and most also understand
that having a current full backup off-site - in the event of a disaster
- - fire, flood, theft for example - their data is very important.
Thanks for the comments. I hope we can figure out what is going on and
eventually help others who wish to do this type of backup with Bacula.
