Question about backing up in Appliance mode

[KOJGrIT]

When using Veeam in Appliance mode, will it copy the attached disk block by block, or will it copy file for file?

[peter.dyer]

All backups, regardless of mode, are block by block.

Thanks for the replay.

@KOJGrIT: what do you mean by appliance mode ? do you install and configure a Windows Server VM to be the backup server of the other virtual server in the same SAN ?

[Gostev]

Albert, please refer to sticky FAQ topic (right under New Topic button) for extensive information about the Virtual Appliance mode. Thanks!

thanks for your reply Gostev, I found this to be interesting:

Q: I have iSCSI SAN and running Veeam Backup in a VM. Can I use direct SAN access mode?
A: Yes, you need to configuring direct SAN access using Microsoft iSCSI Software Initiator bundled with Windows. Our customers report best results with Windows 2008 R2. If your Veeam Backup is installed on Windows 2003, be sure to review the corresponding known issue of the Release Notes document.

So in this case the VM must be installed with the following:
Microsoft iSCSI software initiator - Windows Server 2008 R2
one vNIC - Enhanced VMXNet3 connected to the production network (Internal LAN subnet vswitch label)
one vNIC - Enhanced VMXNet3 connected for each iSCSI network connected to this ESXi (iSCSI LAN subnet vswitch label) ?

cmiiw.

Yes.
