First attempt at every backup fails. Second attempt works.

I'm getting a VDI error on the first attempt to run a backup followed by a memory profile, and the second attempt works every time.

Here's sample output:

My guess is that the auto step down in MaxTransferSize is being invoked, but my concern is that the process is failing as far as SQL Backup is concerned - at least in terms of it firing a MAILTO_ONERROR notification.

Is this expected behaviour or is something else going on.

If it were up to me, I'd expect to see these messages if I had MAILTO_ONWARNING set, but not with MAILTO_ONERROR :)

Thanks

    Hi Bernard,

    The suggestion about having an option not to email warnings is already on our list of things to do.

    The backup is behaving normally, so I don't think it's good to worry users in this way over a normal process of stepping down the max transfer size for the backup when buffer issues occur.
