Hi
Didn't you look at my previous mail? We are talking about how many db backups that is necessary to keep in the library. This is because Miles doesn't have any slots available, and he's having problems because he now needs to put in another ½TB of data in the library.
Therefore, he was wondering how he could save space within the library.
Best Regards
Daniel Sparrman

Yes of course I have policies. I am not using LTO or Magstar. I am using AIT
tapes. We do not keep the database backups in the library. We ship them
offsite to our vault. At the most we have 2 - 3 database backups in the
library depending on what day of the week it is.

Don't you have policies in your TSM server?
Using an LTO library, this would require 12 LTO Ultrium tapes, which means
2.4TB of lost space, if your database isn't big enough.
Hope you're not using LTO tapes, rather Magstar tapes.

I don't think keeping two weeks worth of database backups is to protect
against database corruption. If your database was corrupt you would know it
right away. Rather it is to enable you to retrieve data that was expired
that would be lost without being able to go back x number of days.

Hi
Yes, we only keep 2 copies of the database backups in the LIBRARY, and
another 5 copies of site.
However, this guys problem was that his LIBRARY was full, and that he
needed more space/slots
available for scratch volumes in his LIBRARY.
And, there are other ways to be certain that you're database isn't corrupt.
You don't have to keep two weeks of daily database backups in your library
to accomplish this.

You only keep 2 copies of your database backups? I keep two weeks worth!
You realize that without the database backups you can't restore your TSM
server farther back than two days ago.

Hi
How's you're reclamation set up? The default value is 60, but if you take a
look at your tapes, i'd guess you have about 10-20% reclaimable space on
your tapes.
The L32 has 320 MagStar tapes. Is it C-model XL version tapes? In this case
every tape should hold about 15-20GB's each.
If you could make all your tapes full, without any reclaimable space, you
should be able to save 2-3GB's per tape.
With 320 tapes, this should be a total of about 600-800GB of free space.
Try setting your reclamation threshold to 5% over the weekend, and you
would
probably get some more tapes.
The other thing to look at is how many versions of the DBBackup are you
saving? Recommended is at least 2, but if you're using more than that, it
could be a good idea, to look this over to see if you can save any tapes.
How is your copypool tapes? To look at the reclamation threshold on these
tapes could probably be a good idea.

I have a similar but not as bad situation. 3575-L32 maxed out with about
60 tapes out of library and LTO coming in a month or so. The "MOVE
MEDIA" command is used to move tapes out of library. You have to have
your OPS folks on the ball as when one of those tapes is needed, there
is a message that pops up on console each minute until tape is checked
back in.
Reclamations and restores are mostly what needs tapes, so if you can plan
the times of these that will help. With your 200+ tapes out of library,
this will most likely be a LARGE extra operation for them (and YOU) to keep
up
with. Removing collocation will conserve tapes but don't know how you
have in thisn state and how long it will take to change over.

Hi folks,
I have a situation where our company has two backups systems, TSM being one
of them. The 'other' backup system doesn't work for various reasons and we
are planning to move the servers that backup to it to TSM. On the weekend
that other system fell a part. Now I need to backup about 500GBs into a
Magstar L32 that really doesn't have that much space. I'm in a tight spot
and I need some creative ways to backup that much data. Here's what I've
been trying:
- turn collocation off, or from 'filespace' to 'on'
- reviewing old nodes and the largest filespaces, but this didn't save to
much
- I don't think I can reduce any copies or the length of time that the
copies are stored
Here's what I do have:
- I do have 8 x 36 GB disks that will be here soon
- a ton of tapes, no room in the Magstar, but I must have 200-300 extra
tapes
- I also have 24 x 18.2 GB disks right now that are used for my disk pools
and 4 x 9.1 GB disks that are used
So I was thinking I that I could:
1. use the 36 GB disks for a primary pool. Still sending the data offsite
(copy pool) because I have a lot of tapes, OR,
2. start taking tapes out of the Magstar and just setting them aside, when
they are full
I do have a LTO coming but not for 2-3 months.
I could really use a creative idea to store a lot of data. I have the tapes
just not the slots inside my Magstar.
Thanks Miles
