It is common to hear that for backup there is not sufficient space on my server or my server disk is about to full. And now I want to take my RMAN backup directly to remote location. How I can achieve that?
Now before taking backup let think in which type of storage on remote location you want to take backup? Is it a disk or to the tape. Below is the procedure for both types.
Taking Remote RMAN backup to Tape
1)This is of no different as you access remote tape devices.
2)First install and configures the drivers of the tape device on the local machine box.
3)Make sure that you can access to tape by making copies file to tape.
4)If step3 is successful then RMAN will be able to take backup to tape directly.
Taking Remote RMAN backup to disk
1)Remember that direct disk backup to remote location using RMAN is not possible as we can do it on local disk by using FORMAT parameter specifying local disk.
2)As RMAN backups to DISK can only be taken to some 'part' of the target database server. So, remote location will not work.
3)The thing you can achieve goal is to share remote location, then mount it on the target database where you want to take backup. An example of how to share folder and access it on other machine is discussed on How to share and Access file on Solaris Machine
4)Take RMAN backup to this mapped location using FORMAT clause. Based on this a remote backup is taken in http://arjudba.blogspot.com/2008/10/backup-to-remote-location-fails-with.html after sharing remote location and map it to location /export/home/oracle/remote/.
