You choses to do your backup throught RMAN or Using BRTools. We use BRTools. The SAP basis do the backup/restore. But I control the retention time of the backup.
For my fisrt Configuration I use the RED Book.

and select
IBM Tivoli Storage Manager for Enterprise Resource Planning
Chapiter 4 is were you start.
I use 2 mount points with Multiplexing 4.
For your SAP systeme, I suggest you collocate by filespace and NOT by group. Collocation by group will impact the restore performance..
We test SAP restore every month.. so we had alot of time to fine tune the option in the .sys.opt and utl file.

I have been using TDP for SAP - Oracle since 1996 (before it was TDP) and we have only used the BRTools. It is easy and gives very good performance. If you need help with configuring the opt/sys files and the utl file, please ask away.
We have 2 sessions with 3 multiplexing and sync-write to a copy pool at the same time. Backs up a 3TB DB in about 7 hours.

only tsm for erp is enough!

No you don't need TSM for Oracle agent on this machine
hhm ok, tell me what about RMAN, can i perform these tasks with DP for SAP with BR tool and there is no need of RMAN ?
tell me one thing more, how to integrate BR tool with DP for SAP, i didn't work on BR tool before

yes you don't need RMAN or DP for Oracle... Just install the DP for SAP, it's wizard based installer and helps you to configure it and follow the configuration instructions. After all you'll schedule your backups from DB13 screen of sap gui...

ask to your sap admin/consultant or just use br commands with tsm schedule but I recommend that db13 because it's nice to see the logs/results etc.

yes I understand, did you really read the tdp for sap documentation? you can use log backups and full backups via brtools... again and again... you don't need rman or tdp for oracle...
TSM for ERP comes with two adapters:
1. backint interface - for file based backups triggered by BR*TOOLS
2. RMAN library - for RMAN backups (full and incremental) also triggered via BR*TOOLS (brbackup -d rman_util ...)
No need to use TDP for DB.

Q = cant i take incremental backup using BRTool
A = yes you can, but you have to use RMAN for incremental backups( configuration see TSM for ERP for SAP for Oracle User's Guide )
With the Backint Interface only Partial and Full Backup are supported,
because the backint interface can handle only files and not changed blocks in a file

you take archivelog backups via brtools and it's the same with incrementals via rman... and backfm makes it easier...
"you take archivelog backups via brtools and it's the same with incrementals via rman..."
that is not correct
redologs are db transaction in text form and on restore you have to apply it to the db. transaction for transaction and that's quit slow.
incremental saves all changed DB blocks and that's beleive me is much faster as applying redologs.
but that's not the question or reason for incremental, one of the most reason for incremental is save TSM storage with a justifiable restore performance

I installed TSM for ERP on SAP based oracle server, the setup asked me for Oracle instance SID, what is it ?
I found that tsm for erp has no graphical console I wonder what i do next after the installation ...
On SAP server the BA client is installed and file level backups are going on successfully
Now i just want to connect ERP client with BR tool but i wonder how to perform these steps....
give me any resource where i can find step by step configuration to connect tsm erp with BR tool ...

some background of DP for ERP for Oracle ( DP for SAP for Oracle )
- DP for ERP for Oracle supports:
Backint Interface = file interface ( reading from DISK )
RMAN Interface = block interface ( reding from RMAN )
For both you able to use BRTools for the backup ( How to, see User's Guide )
- Different between RMAN and Backint Interface "incremental" "partial"
Incremental - works only with RMAN, because only the DB known change blocks
Partial - backint can backup parts of the DB ( Tablespace XY )

Backint Interface = file interface ( reading from DISK )
RMAN Interface = block interface ( reding from RMAN )

Some background about Oracle, SAP and DP for ERP for Oracle:
Oracle RMAN
- RMAN ist the Oracle Backup and recovery manager and save the CONTENT of a file and not the file itself
>> backup types = full or incremental , online or offline
SAP
- SAP use for its backups and recovery the BRTools whatever you are using command line or DB13
BRTools using FILES for Backup
>> backup types = full(all) and partial , online and offline
BRTools and External Backup Utility
- SAP has designed an Backup Recovery Interface ( BRI ) to allow vendors to backup the Data to its Backup Solution. The BRTools is the master of the backup/restore process. External backup utilities like DP or DP with RMAN running under control of the BRTools, like a blue colloured worker
- Communication between BRTools and external backup tools will made over
"env variables" ( type of backup ) and files ( backup file list, errors success, .... )
DP for ERP for Oracle ( there is also a DB2 one )
-DP for ERP for Oracle is a external backup utility designed to work thogether the BRTools
( DP for ERP can only be used with an SAP system , for a Oracle without SAP you have to use DP for Oracle )
DP for ERP for Oracle has 3 read/write devices
- FILE r/w files from DISK ( backint )
- BLOCK r/w over a shared library in connection with RMAN
- TSM r/w data using TSM API
Different between partial and incremental
--- partial
= partial works only with files, or better TABLESPACES (TB), to save storage space, it's possible to running e.g. a fullbackup and the next 3 days a partial ( 1.Day TB 1-5 , 2.Day 6-10 and 3.Day 11-15 ).
!!! Restore need some additional time: restore sequence is "1. restore last full backup 2. restore
partial(s) 3. restore redologs !!!
-- incremental
= incremental works with data blocks, that means RMAN searching through the DB for blocks that have changed since last backup.
!!! Restore need some additional time: restore sequence is " 1. restore last full backup , 2. restore the last incremental, restore the redologs !!!
Keep in mind !
" incremental and partial are only reasonable to save storage on the Backup Server "
" incremental backup need nearly the same time as full backup ( checking block for block ) "
"" You save storage but you lose time on the restore ""
"" Design you Backup Strategy based on you "Restore Time Window" ""
