Hi,
I'm no NetApp expert, but as far as I know they have their own piece of=
=20
software which integrates their snapshots with oracle.
Creating consistent backups of a database isn't a problem that a=20
filesystem should solve at all. A simple approach for your problem woul=
d=20
be "Put DB in hot backup mode and then create a snapshot". I'm not sure=
=20
if there is a way to integrate RMAN backups with btrfs snapshots. Maybe=
=20
an oracle expert could help out.
Kind regards,
=46elix Blanke
