I'm really disappointed about this. Especially companies that want to use your product to create a fault tolerant / stable / professional environment and therefore choose to implement an iSCSi failover cluster also want to use WAN file replication to replicate those volumes also to another datacenter/location so they also have made sure the data is available for disaster recovery. As it is not supported by Open-E we need to use 3th party backup programs with all the complex configuration to achieve that information on the volumes is replicated.
So I think it would be nice to see Open-E finding a solution for this.
The real issue is that you can't do a file-level backup with iscsi volumes on the target side because the target-side is supposed to be filesystem agnostic. Now, any client systems that have the iscsi volumes mounted can perform a file-level backup. So, we have a red hat system rsync the files on the iscsi volumes over to an Open-E NAS, and from there we use the built-in "data replication" feature to replicate to another open-e nas at an off-site location. We could actually just rsync the files directly from the red hat system to our off-site NAS, since the "data replication" is just a webgui-ified rsync implementation.
