3 node 11.2 rac using ASM on SAN.
All of the RMAN backups go to +FRA. Any node can initiate RMAN and create backups.
I want to offload the backups from +FRA to a filesystem. Our current backup system can only read cooked file systems.
This LUN also comes from the same SAN. It will have a file system, ext4. It will be visible to all 3 nodes and will be mounted to ONLY the first node. First node will be the one to copy from asm to this filesystem.
If first node is out of commission, I can mount the backup lun to one of the other remaining nodes.
Does this sound like a decent plan or should I go with a clustered file system?
Thanks for you opinions!
Have you looked at using ACFS? Create a very big diskgroup, then create an ACFS volume and finally an ACFS filesystem. create a path on all nodes on which the ACFS filesystem will be mounted.
Example: Using asmca do the following
mkdir /d01/FRA on all systems
DGFRA (4disks at 500G)
Create ACFS volume 1.8T
Create ACFS filesystem mount point of /d01/FRA
set your db_recovery_file_dest=/d01/FRA scope=both sid='*'
Now any node can backup to this FRA location AND any node can copy files to tape or where ever...
This is "supported" as of 220.127.116.11 ( I have used it on 18.104.22.168 and 22.214.171.124 for testing)
