thanks for the info but I seem to be ever increasingly confused by this at the moment so please bear with me.
If I can only connect one server per ISCSI volume does that server that is connected have to perform the backup? If not how can I connect to the ISCSI device with my external backup server running program (Arcserve R12) to backup all data on the device?
If I have to create a share of the volume from each connected server how can I overcome the issues with files that are in use? Can I use the connected server's shadow copy feature or would this not work.
Basically I am running Hyper-V Server 2008 and have my virtual hard disks stored on an ISCSI volume, I want to be able to back these virtual hard disks up on a daily basis, but need a way of accessing the files as they are always in use, would I need to have a period of downtime on the virtual machines, whilst the backups happens.
Any more help would be greatly appreciated.
