Re: Delete a specific backup

It sounds like you are trying to manage your backup tapes (as in traditional
backup software -- like every other product out there);  you should just let
TSM manage the tapes -- if you have a failure on a daily incremental, you
simply re-run it the next night (or sooner, if you are so inclined)... TSM
will still only backup the new/changed files (assuming you are configured
with the standard, typical situation).  There are cases where a customer
wants "full" backups more than just the first time a full-incremental is
run -- but that is not typical, it's only because they are trying to
consolidate mission-critical backups for the fastest restore, but there are
better ways to accomplish that goal than re-sending the whole file system
across the network (such as weekly image backup, and/or collocation on the
file-level incrementals).

Your question suggests that you might greatly benefit from a better
understanding of the progressive-incremental technology that TSM employs to
back up file-served data;  this product will use far fewer tapes to handle
storing several versions of any given file, and (when configured properly)
will manage the tapes and restore the data faster than its competitors.  For
example, with your 200 GB file system, it probably has thousands of files;
using the "Getting Started" book, rule of thumb, you'd need only 200 x 5% x
#-versions, (say 14 days point-in-time restore capability), 1.7 times the
file space occupancy -- one full copy plus 5% for each additional day in
your point-in-time restore criteria (guessing that less than 5% change per
day across the most recent 14-day period).

With TSM, there is no need to delete a specific day's backup of flat-file
data, plain and simple;  if that statement makes no sense to you, then you
need a better understanding of the product -- your email is from IGS, so
that would be highest recommendation.  Now, all of this gets more "involved"
when discussing backup strategies for large data base volumes;  see the
applicable TDP books and discuss with the dba's supporting the application
to determine what's needed.

Thank you for your response Daniel.
But what is the difference if I do full backups in between ??? If I see a
filespace of incremental backups as one.

I try to explain better my question. For example a I run a incremental
backup every day, of the file of 200 gb aprox. If for any reason this
backups fail, I want to delete this version, and reuse the tapes.
Is possible this ? ... yes .. how ?

Thank very much !!!
Best Regards

Hi

1. No, you cannot delete a specfic day. However, you can setup your
management classes to handle this, or do full between incrementals.

2. You will have to do a backup stgpool "stgpoolname" "copypoolname". You
cannot set volumes from a primary stgpool offsite, only copypool volumes.

Tivoli handles off-site copies using something called a copypool. This
storagepool is normally only used for off-site and media protection
purposes. If you haven't got a copypool, you will need to define one, to
be able to handle off-site copies.

Hi ... people !!! I have two question ....
1.- There are any way to delete a specific backup of one day or one week ?
I running a incremental backups since Monday to Thursday, and archive on
Friday. I want to delete all backups of a specific week. Do any people
know
how do this ?

2.- As I told ... a run backups every weeks, and every Monday I need to
send offsite a group of tapes that I used in the last week. Is possible do
this.
I try to put the tape in status offsite, but I receive an error, that the
tape "is not belong a copy storage pool"
There are another way, because I stay a tape in normal status, this can be
required in any time and I don't have this tapes.

Thank You very much for your time.
Best Regards.
