Hi,
I have 2x40TB domains each are exported with iser/iscsi with ib and 10Gb interfaces.

For sure they are RAID6 storage little bit save on failure.
But I was wondered if any way to backup those domains. particularly master one.

I was thinking somehow DRBD based replication, with lvm snapshots etc. But it looks like overkill.

Will be nice somehow to deploy replicated/HA Master domain with ability to backp on tapes as well.

Any ideas are welcome.

Thanks,

Arman.
