Oh, and I should have clarified -
You are going to use TSM for Mail regardless.
It's just whether or not you have Flashcopy assisting it.

I think it depends on your environment, your hardware, the size of your mail
servers.
The original use of Flashcopy manager (this is about the third name for the
product - it was originally something like "TSM for hardware") was to
facilitate use of snapshots of volumes taken with IBM disk hardware. And that
part only works for IBM hardware - San Volume Controller(SVC), DS8000, etc.
(not EMC or Hitachi disk, as they have their own snapshot software). The idea
there is that you get a quick snapshot (based on a copy-on-write trackmap, I
think) of the volume, then do the backup from the copy, not the primary.
Depending on your environment, you might also consider it an advantage to be
able to do an almost-instant-restore of that backup from the disk copy, rather
than from tape. And with Exchange+VSS, at least, you can keep multiple
versions of the VSS backups on disk, in addition to the tape copies.
TSM for Mail with Exchange 2010 requires the use of VSS snapshots for the
backups. TSM for Mail with Exchange 2007 it's an option, not a requirement.
But even though it's a VSS snapshot, my 3 customers don't keep the data on
disk, it goes straight to tape anyway.
So if you have a huge Lotus environment and IBM disk-snapshot-capable hardware,
I'd look into it, see if you can leverage that disk capability.
If you just have a garden-variety modest size Lotus environment where you don't
have issues with time windows doing your backups, and you just want a typical
weekly-full-to-tape plus daily incrementals, maybe no advantage at all.

Hi
I have been asked to implement a solution for backup of Lotus Domino Servers
using TSM. At this moment in time, i am unsure if they will be running this is
on Windows, Unix or Linux.
I have done this previously and was intending to implement a similar
solution: Weekly full backups, daily incremental backups and frequent
transaction log backups, using domdsmc commands.
However, a colleague suggested using Flashcopy Manager, something i am
unfamiliar with at the moment. Having looked at the documentation, i can see
that Flashcopy v3.1 for Windows can create VSS snapshot backups of applications
such as Lotus Domino Server.
I attended a presentation in Germany in 2011 where Del Hoobler talked about TSM
for Mail and specifically, Lotus Domino Server, using the techniques i had
previously used. This was my preferred method.
So, TSM for Mail or via Flashcopy. What are the benefits, if any, of using
Flashcopy?
Thanks
