Tony, could you explain a bit more. I am somewhat confused.
You (instead of CA?) "fought" to fix Arcserve agent for 8 months??? Was it
so broken? What means 95% operational, what are the rest 5%, what was the
percentage before those 8 months? And what on the end is "tolerable",
something you still did not got fixed?
TSM does NOT do brick level restores because Microsoft does not do it -
the backup APIs are for information stores. Other vendors are attempting
to use messaging APIs and DO NOT restore messages but create new ones with
same content. This was explained on this list many times.
There was something in one of the discussions remark that Microsoft (not
Tivoli) is planning to enhance/modify their APIs. But if Microsoft does
not provide an API for mailbox restore then Tivoli simply would not do it.
There is a joke about a gynecologist who painted a room through key hole.
But I would not accept all rooms in my office to be painted using this
technology and with that speed.

Subject:        Re: TSM and MS Exchange (MailBox Restore and Exchange 2000 
Improv ements)

        Actually, we are using Arcserve 2000 to backup Exchange5.5 on W2K
member serves. We fought Arcserve for over 8 months to fix their agent and
it looks like they have it 95% operational and tolerable.  We are seeing
through=put speeds of up to 100mb/minute. We are backing up servers with
databases of up to 15gb. All-be-it we are using old DLT4000 technology,
the
backups are getting done and we have been able to restore peoples
individual
folders (i.e. sent items, inbox, etc...)

Now I have heard that TSM might be doing this in version 5.1x, I do not
know
how true this is, but I now they DO NOT do it now...

Hope this helps
