Have you thought about mirroring the remote data to local storage,
then backing up the local.

Hello everyone,

We have similar situation and questions...

We also have a T1 line for doing Monthly Archival Full backups that take 6 full 
days to complete (line is completely saturated during this time), if all of the 
daily changes are not too large which shares this line also. The line is 
dedicated to TSM backups/restores. What I was thinking for speed of backups and 
being able to certify that every backup happens quickly and completely every 
night is to setup a second TSM server that would backup at that location to a 
virtual tape library then trickle those changes to the main site to tapes or to 
the san at that main site and then to tape. Is this possible or a valid 
solution? We are also running TSM 5.3.4 and all clients are current with 5.3.4. 
Possibility of adding more bandwidth i.e. T2 or greater is good.  Which is 
better more bandwidth or a second TSM server? Can TSM servers work together to 
get backups done, kind of like a load balanced Backup?

Thank You,
Dan Lane

Mark -

Exactly what is trying to be achieved?  It kinda sounds like they are
trying to perform what amounts to a full backup over what was a high-
speed link in 1962, based upon old-thinking full+incremental
backups.  TSM Incremental may supply what they actually need;
otherwise, client compression would be the best they could probably
do with the networking they have and approach they are trying to
use.  We could advise better if we had more information.
