thank you for your explanation! the only difference is the usage of the network-connection, isn't it? iSCSI-SnapDrive uses its dedicated network-connection, whereas a RAW Disk is connected thru the normal Intranet-network-connection! Am I right?
is it possible to backup the RAW Disk over SAN?
I have encountered the following error message on my test-backup:
Backing up file "[vm_os_vol0] dbtst2008/dbtst2008_1-rdm.vmdk" Unable to establish direct connection to the shared storage (SAN). Please ensure that: - HBA is properly installed in the Veeam Backup server computer, or software iSCSI initiator is configured correctly. - SAN volume can be seen by operating system in the Windows Disk Management snap-in on the Veeam Backup server. - Read access is allowed for the Veeam Backup server computer on the corresponding LUN (refer to your SAN documentation). Direct SAN connection is not available, failing over to network mode...
the backup-server is mapped to the raw disk (if it does matter) ... btw. [vm_os_vol0] isn't the right volume - the raw-disk has its own volume on our NetApp!
edit: the RAW-Disk is listed in the Windows disk management of the backup-server!
edit 2: i have started a second run and now the error-message didn't appeared anymore 😉
