Re: ASM - hardware mirroring vs. Oracle mirroring

Here's a problem I ran into with ASM a while back.

I was exporting large partitions as a means of backing them up for
historical purposes and the intent was to put them on tape. Unfortunately my
setup had almost all space allocated to ASM so very little filesystem space
existed. expdp will still export to a ASM disk group so that part was
covered, but now I had a export file in an ASM diskgroup and no way to use
OS commands to back it up. RMAN doesn't allow for backing up export files,
so I was left with no way to get the file straight from ASM onto a tape and
no filesystem space to put the export file on. I was stuck.
