Hi all,

I want to start a discussion about ADSM and backing up big file servers. In our
environment we have 16 Mbit token-ring networks and we are using ADSM to back
up all of the critical data.
The biggest file servers that we use at the moment has a 18 GB data partition.
Backing up these servers with incremental backup is no problem. It works for a
long time, everybody is satisfied about the short backup times. But what will
happen  in the case of a disk failure. If the server was very full, you have to
restore up to 18 GB. With our kind of netwotk this would take about 20 houres
or more.
What I want to say is; The disks in the servers  become bigger and bigger, the
backup time is still the same because of the incremental technique from ADSM.
I'm sure that most of the useres from ADSM don't think about the long restore
times in case of a disk failure.
The difference between the network speed and the size of the data disks becomes
bigger and I see a problem in this fact.

What are you think about these? And how could we solve these problem?
