Re: AS/400 backup to TSM

Hi Joe

Thats correct. Only the "user data" can be backed up using BRMS and the 
TSM api.

To backup all system-defined objects, you will still need to use a locally 
attached tape library/drive.

We've also seen perfomance issues with this solution, as the BRMS and TSM 
api first backs up to disk, and then transfers the data to the TSM server. 
During testing, making backups to a locally attached LTO1 drive fast 7 
times faster than transfering the data to the TSM server(which was based 
on AIX).

I dont know what kind of library you are using, but another way of going 
at it is partitioning the library(if you're library has this option) so 
that the AS/400 can have it's own drives within the library.

Hi All,

We have a potential AS/400 client.
We are running TSM server on Win2000 5.1.8.0
I'm not as/400 guru; to be more precise I don't know anything about 
as/400.
I downloaded Redbook "Practical Guide to Implementing TSM on AS400 
sg245472" and try to get familiar with as/400.
I know that we have to use tsm api for as/400 and that it works together 
with BRMS/400. Customer will help us to install it.

Question that he asked me: " Is it possible to have all data backed up to 
TSM or we still have to use our tape backup".

This Redbook refers to as/400 v4r3; and it says Operating system, system 
libraries, security objects, IBM supplied libraries and licensed programs 
CAN NOT be backed up to TSM; they can only be saved to local device 
(tape). So, we cannot fully recover as/400 system using only TSM.

Does anybody knows if this is true, or something changed in newer 
versions.
