I have architected this extensively in one vendor's environment. With a
well-designed architecture, all of the issues that you mention (except not
having secondary servers to mount the images on to do the backup) can be
mitigated. For example. You can check the state of the tablespaces
the suspend script ran. I
guess we expected that the tape would go to SUSPEND mode when the write
finished, but 4. above seems to belie that expectation.
Can anyone comment on the expected behavior if an attempt is made to suspend a
tape when it is writing?
Thanks,
Mark

Hello,
You cannot change the attributes of a tape when the tape is in use.
I had the same problem with you and my solution was to make the script
Folks,
Assuming a mix of about 50% VM and 50% physical clients, and a large ( several
hundred) Oracle and SQL Server (almost 2000) presence, are there ant rules of
thumb about how many clients a NBU backup admin can handle?
Thanks

There are pros and cons.
Sorry, I have nothing to add to what Mark has said, other than to call out
his no vendor does it :)

time you backup the filsystem, and then after that, you only
backup the pieces that change, while still realizing the benefits of

Paul,
The fact that you get half of the speed of a single backup for a ITC
backup may be telling. Since ITC does it's duplication on the client
(i.e.: two backup streams to the media server) as opposed to on the
server (i.e.: one stream from the client and two streams to the media
