Question1:

1-  Can we backup RMAN to another server, which we want to use just to save Oracle RMAN backups ? For example keep 10 days worth of backups on that server. If yes, how?

2-  We keep 2 days worth of RMAN backups on our Oracle Server.  Can we copy those backups to another server to retain them for about 10 days? For example, we copy RMAN backups every night to that server.  If yes, how?
