SAN Media Server Backup using Hitachi copy on write

Hi All,

I am looking at having all my Geo clusters using Hitachi storage to use copy on write and present the LUN to a media server. I dont want windows to put a signature on this LUN so it wont be mounted, just presented on the media server, how can it be backed up?

On 7.1.0.4 but upgrading to 7.5.0.5 over the next few weeks. Is there any snapshot technology (api) for Hitachi available?

The only way I can see it working is if the LUN is mounted to the media server and has a drive letter, to do a SAN media server backup, even then I want 20 odd Geo's which have an X:\ to copy to a single LUN which needs to have all these mount points underneath.

Anyone have any idea's?

Thanks,
