Re: could not write to log -> PANIC -> System down

My understanding of VSS is that only one non-VSS aware app can access
the data at any one time.  All I meant was that if their NetBackup
version was old that they probably cannot benefit from VSS since I doubt
the Win32 PG port knows about it either.

Any backup system that is not transparent to processes running on the
system seems to be flawed by design.

In those messages "processing" just means it woke up to see if there
was anything to do. It probably didn't do anything. Waking up every
minute is not that big a deal...

Have a nice day,
