"Do I understand you to say you have to keep your NDMP backups around for
7 years? The tape media isn't even meant to last for 7 years. Do you

NAS data? That's a tough requirement."
I thought I'd change this to a new topic. I hear this type of comment
alot on backup forums. From an engineering perspective, it completely
makes sense. It also makes sense that people in backup forums think like
engineers!
Just another perspective. When I started with TSM, I was working for a
software development company named "Tivoli" who obviously cared about
their backup data. The mantra of the backup guys was "Restores are more
important than backups!" I.E. do periodic test restores, and if a
restore request comes in and conflicts with a backup. cancel the backup
in favor of the restore.
Several years later, I start working for a bank. After working here for a
few years, I realize the mantra is now the reverse: "Backups are more
important than restores". Meaning. the main reason we perform backups
and retain them for 7 years, is so we can show an auditor our settings and
say we've done it.
We very rarely have to restore anything that old, but we very often have
to show records of these backups.
One last note, I have been involved in legal discovery projects where we
actually did have to restore 7 year old data off of old DLT IV tapes. We
found tapes with dried up BBQ sauce on them and all sorts of damage.
Luckily, between the multiple storage pools we were able to rebuild all
the data. The DLTs never actually failed due to age (only by a
tomato-based attack!)

Shawn

Shawn,
Do I understand you to say you have to keep your NDMP backups around
for 7 years? The tape media isn't even meant to last for 7 years. Do
you have customers that actually think they will need 7 year old copies of
you NAS data? That's a tough requirement.

"You will have to move the NAS clients over to the new TSM server,
and wait for the old backups to expire before you retire the old backup
server."
That's what I figured, but I'm not keeping that thing around for 7 years.
I guess we'll have to stick with Windows :(

Shawn

Re: [ADSM-L] Change TSM Platform
Shawn,
>From my understanding, you are going to have to set up a new TSM server,
and migrate the clients over to it. You can use the export commands to
export policies and client data from one TSM server to another directly
across the LAN. That will make it somewhat less painful, but depending
on how many clients you have, this could take a few weeks. You will
have to have enough storage capacity on the new system to absorb all
this data. If you only have one tape library, you will have to set up
library sharing, and have enough tapes to have two copies of some
clients' data as you migrate clients over. If you want more detailed
instructions, please ask. Many of us have been through such migrations
before.
According to the help on EXPORT NODE, you can't use it on nodes of type
NAS. You will have to move the NAS clients over to the new TSM server,
and wait for the old backups to expire before you retire the old backup
server.

You will be moving from x86/64 architecture to Power. They are binary
incompatible. You cannot upload DB from x86 to Power (this is what
backup/restore essentially doees). Your only option is to export DB.
Don't know about the NDMP.
