If you take the snapshot, you can use NDMP or dd without getting oracle
in the picture.

Hi there,
Quick question following up on this thread:
After you to take the snapshot how do you backup the snapshot ASM
volumes (they are still RAW)?
Do you use DD or ASMCMD or any other way?
If we need to use asmcmd that would require an Oracle license. I am
trying to avoid that.
Thanks

With split-mirroring or snapshot solutions (EMC or NETAPP or anyother
vendor) when working with ASM you need to carefully layout the Disk
Groups.
For example you should (or shall I say must) NOT mix databases in same
Disk Groups, because when you run the snapshot you will be backing up
all databases in the Disk Group, that is not a problem. The problem is
when you have to restore, when you restore a snapshot you will be
restoring several databases!
Thanks

What kind of limitations are you referring to? Could you share a few
more areas/details?

Any major issues you ran into?
Thanks again
