Backint/brrestore for refresh of test system?

Question

We have a sandbox system that we refresh periodically from production. All systems are running Oracle 9.2. We use the backint interface and brbackup (called from DB13) to back up the production system daily, but we do not back up the sandbox.
To refresh the sandbox system, I copy down the latest online backup of the production system and perform database recovery. We've had some performance problems in the restore, and our backup system vendor (Legato) has advised me that I should use brrestore instead of Legato's recover utility to get the files back from tape.
Here's the question: Can I use brrestore to restore files from a backup of a different system? And if so, what is the procedure? With the Legato tool, I can easily pull down files from a different database and relocate them wherever I like. Can brrestore do this?
Thanks for your help.

Dear Eva,
I use Legato as Backup tool on My windows environment.
I have understood you need to perform a restore keepind the same Oracle sid.
You have to launch a brrestore on the target server passing a .utl file ( example restore.utl in the directory %ORACLE_HOME%\database\ ) similar at the .utl file ( example backup.utl ) you have used to backup the database on source server.
In the Restore.utl you have to add the parameter:
client = servername.xxx.yyy.zzz
This is the client who have performed the backup of the database. On the legato server you have to modify the definition of the client of the source server. In the remote administration tab you have to add the target server as remote administrator of the source server.
After that you have:
1.Check that in the file init<TARGET_SID>.ora the rollback segment are the same than in the file init<SOURCE_SID>.ora ( I think are the same because you have already done other restore )
2.Copy from  <SOURCE_server> a <TARGET_server> the last file .aff + and the file .log under directory sapbackup
3. On the <TARGET_server> modify file .log. You have to keep only the row relative to file .aff you have copied for the restore
4. Optionally: you can modify the file .aff if you wanto to distribute sapdata file on different drive letters on the target server
5. Run on the <TARGET_server>: brrestore -m all -d util_file –r %ORACLE_HOME%\database\restore.utl -c
It seems difficult. The first time we launched the restore we spent a day only to understood the procedure.
Now we restore 200 Gb of database in 2 hour.
Kind regards
