Robert,
If your WAN connection has enough bandwidth, I
would use virtual volumes to store copypool data
on your other TSM server. So, location A would
have another copypool that would actually store
data at location B and vice-versa. Of course each
site's tape library would need to have enough
capacity to store the other site's data. I have
been doing this for several years and it works
great. However, I still send tapes off-site
everyday. In other words, I have two copypools on
each TSM server - one using actual tapes that go
off-site and the other uses virtual volumes on the other TSM server.
I would have another talk with management also.
Remind them how important the data is. In my
opinion, getting cheap in this area is the
equivalent to playing with fire. Its not IF you
are going to get burned but WHEN and HOW bad you are going to get burned.
Thanks,

Hello.
I have the following problem:
We have two locations with a distance of 80km between them.
At each location we have a TSM-Server which hosts the backups for the
location.
Until last week we brougth our copy-pool-volumes to a safe which was maybe
10km from the location. When we needed one of this tapes, we went there
with a car and had the tape in the library within maybe one hour. Now we
had to give up this external safes because of the costs and do the
following:
the copy-pool-volumes from location A are brougth to location B and the
volumes from location B are brougth to location A.
And now the management has the great idea, that we could do the following:
if we would need a copy-pool-volume on location B, which is actually stored
at location A 80km away, we could put this tape in a library at location A,
read the data there and transport it to the TSM-Server at location B via
our WAN-connection.
I told them that this is not possible, but they think it MUST be possible.
Could this really be done or am I rigth when I say that it is not possible?
How would it be done if it is possible?
I had some ideas like checkin the volume, make a move data to disk, which
is accessible as share to the second server and restore from there. But how
would the two servers now, what is going on?
Or create a second TSM-instance so that we have both TSM-Servers at each
site. But how keep them actual?
Hope to get answers soon.
