Backup Esxi with Veeam
The backup of an ESXi can be performed using different mode.
- Direct storage access mode
- Virtual appliance mode
- Network mode
Less efficient than Direct storage access mode, Virtual appliance mode offers better performance than Network mode. It is recommended to use this mode in case the proxy backup role is assigned to a VM. With the Virtual appliance mode, Veeam use VMware SCSI HotAdd capability for attaching device to a VM while the VM is running. Thus, during the backup, the disks of the virtual machine are attached to the backup proxy. The data is written directly (for backup) or recovered (for recovery) from the data store. This avoids the use of the network, which is much more expensive in terms of resources. It’s possible to use Virtual Applicance mode for this operation :
- VM copy
- Quick migration
- Entire VM restore
- VM disk restore
- Replica failback
Prerequities for Virtual Applicance Mode
For use Virtual Appliance Mode, you need validate this prerequities :
- Backup proxy must be intalled in a VM
- The ESXI host on which the backup proxy is deployed must have access to the virtual machine datastore
- Backup server and backup proxy must have the latest version of VMware Tools installed.
- SCSI 0:X controller must be present on a backup proxy (without this controller, Virtual appliance transport mode will fail).
