(War and Peace again - sorry):
Thanks for all of your responses both on and off list. I've put some feelers
out elsewhere on this too (many thanks if you're reading) and have had some
interesting and contradictory responses!
In summary, there do seem to be some folks out there running with
My heart leapt when my RSS reader presented me an article in the TSM
udpates feed from IBM with the heading, Keeping more than one TSM
server database backup on a tape. As I'm implementing a new server
using 3592 drives, I haven't been happy with my options for this
particular issue. Maybe, I

At this time please consider submitting a paper proposal during the next

Hi, Sabar.
I couldn't find a TS7569G via Google, but on the TS7650G, also a
deduping VTL, after data goes through the factoring (dedup) algorithm it
is run through a compression algorithm. You probably won't see much
deduplication, but on the first backup you should see a decrease in size
Funny, but I was researching the TS7650 yesterday and found this article on the
IBM website. Pretty good detail about the product in a non-TSM environment.

And then this on in the TSM environment. I think this one might have
You will have to let RMAN do its job. Every RMAN backup piece and sets
have unique file names and will never place a prior backup into an
inactive status.
How would you expire a RMAN backup since every backup piece is still
active? Short of mass delete on filespace.

We have the same setup. TDPO backups go to separate nodes that have use
their own pool. We have ongoing problems with RMAN deletes not changing
the file in TSM (rman backup pieces) to inactive status, which are then
removed during expiration. We don't know if it's RMAN, TDPO, or us with

Gee. Our 3592 tapes cost somewhere around 100 dollars. We keep 5 days worth of
TSM DB backups. $500 is real cheap in order to keep a copy of our most
important DR resource on our most reliable backup medium.

Hi, Kelly. Heh, you're right, that's a pretty funny document on the TSM
side.
I was of the same mind about dedup until I started getting familiar with
the TS7650. The fact that it's in-line and that it does a binary diff
after signature match addresses most of the concerns that I had. And I
I agree. I want my TSM DB backup on the MOST RELIABLE MEDIA/DEVICE I CAN
GET.
If you EVER need that DB backup tape, it's because you are already in deep
do-do, and in a hurry to fix it. The last thing you'll want to deal with is
the risk of encountering an I/O error on a DB restore...
On Fri,
I go a step further - I want the ability to cut two matching copies of the
database backup to two tapes simultaneously. I'm currently running two backups
back-to-back, but I'm unable to have sessions disabled for 40 minutes, so they
are NOT identical backups.

I haven't googled it just yet, but I though you folks may have references as
to the best TSM server platform.
Currently targeted for AIX, but the server consolidation crew is throwing
around HP Linux.
Any URL's would be greatly appreciated.

Why do you hate all things dedupe?
