I have RAW LVM volumes I've exported as a snapshot from a Falconstor/EMC Symmetrix virtual SAN appliance. Upon these logical volumes are Xen virtual guest servers which are present to a backup server (Linux box with netbackup client) when we mask the SAN snapshot (timemark) LUNs to the media server.
I'd like to send these guest images (which are within a LVM logical volume) from a SAN snapshot off to Netbackup for tape archival, without converting the guest image to a file on a filesystem readable by a netbackup client .
Whats the best way I can send the raw data from a physical volume (SAN lun) to Netbackup ? I know its possible as the Oracle RMAN tool does this for Oracle ASM disks.. I'd like to do this with a linux native tool.
