There are next ways to backup Oracle databases using TSM:
1) using RMAN + TDPO + TSM Client to TSM server by periodic full backups and 
incremental backups on other days;
2) using RMAN + DDBoost to Data Domain by periodic full backups and incremental 
backups on other days with Data Domain de-duplication;
3) using RMAN to local disk with following backup of flat files to TSM Server 
using TSM Client;
4) using direct TSM backup for Oracle database files using TSM Client  (offline 
backup).
The first option is a classical TSM backup for Oracle databases with quite 
solid expenses for licenses, but most reliable in comparison with other 
options. We are using this way for many years and I can provide complete set of 
required scripts for Unix environment (contact me by direct E-mail);
The second option is the fastest way to backup Oracle databases directly to 
external Data Domain storage. RMAN is free (part of Oracle license), but you 
need to pay for Data Domain system itself with DDBoost and de-duplication 
licenses (maybe 10Gb/s network is required as well for mentioned capacity). 
According to stated Oracle database size this is preferable option (in my 
opinion).
The third option is almost impossible to use due to huge disk space 
requirements (more than double capacity is required on local disks). It can be 
used only if disk space is not a problem for customer.
The forth option can be used for small databases and for not 24/7 applications.

Subject: [ADSM-L] Oracle v9 backup and restore without TDP

Hi guy's,

A customer of ours is investigating cutting out the Oracle TDP for Oracle
v9 and replacing it with rman backups to disk that get picked up by the TSM B/A 
client.

I am wondering if people here are doing this already.

I'm no Oracle or rman man but I wonder if you can create a workable environment 
with scripting and procedures, I understand we need disk space for the 'dumps' 
to disk and some space to stage the restore from TSM before it goes back to 
Oracle.

But how about archive log backups and how to go about telling rman a backup is 
back on another disk ready to restore to Oracle.
Can you script the name of the backups with rman and is this usually done with 
the B/A archive function or the backup function.
I can image that the Oracle naming might be an issue.

If anybody here could give me some pointers that would be great, it's a fairly 
large Oracle environment with full backups of more than 40TB's and single 
database or multiple TB's.

Regards,
   Stefan
