Re: RMAN - Remote vs Local Backups

Metalink Note 73431.1 has an RMAN Compatibility Matrix. Target RMAN Catalog DB Catalog Schema 9.2.0 >=9.0.3 >=8.1.x >= RMAN executable

An RMAN920 schema can be created in an Oracle 8.1.6 database that contains the recovery catalog for Oracle 9.2.0 databases.

Have Fun :)
