All I can recommend is that you do some TESTING (you can use FTP) as soon as
possible
.
You won't likely be able to achieve the full 100-Mbit/sec throughput, and
will you have the full bandwidth dedicated to you?
And there can be many pieces of hardware (hubs & routers & gateways, oh my)
beween you and the destination, any one of them can slow you down.
SO test NOW to see how long it will really take to send/receive 50GB of
data.

Subject: Backing up DBs around the globe
We have a client who wants to back up his databases (MS SQL
and others) from one site to another site (location of TSM-server)
in another town a few hundred kilometers away. The connection
will be a 100-MBit VPN-tunnel. So if one site is lost completely,
the backups and the TSM-server would be ready for restore at
the other site.
So far this seems ok (disagreeing opinions appreciated :).
Now it seems more likely this other town will end up (or rather
down) in Australia. Has anyone experiences with medium-to-high
volume backups over a global distance?
No reliable numbers are available; I guess the bigest DB size is
somewhere in the range of 10-50 GB.
Platform will be Windows, TSM version will be the best I can get.
Thank you for your time.
