ASM backup strategies with SAN snapshots
Hello folks,
in one of our setups we have a database server (11.2) that has only binaries and config (not the datafiles) and all ASM disks that are on the SAN. The SAN has daily snapshots, so the datafiles are backed up. My question is, how do I proceed if the database server fails and needs to be reinstalled? My question is how do I tell to the grid that we have already a diskgroup with disks on the SAN. I found md_backup and md_restore, but I am not sure how / when to proceed with md_restore.
I have searched some time, but I am quite confused with the approaches, please note that RMAN is not an option in this environment.
Thanks in advance
Alex
