Backup Hyper-V Server with Veeam

Backup Hyper-V Server

Veeam Backup& replication offers complete integration with Hyper-V. It is therefore not necessary to install an agent to recover data from a VM. Backup is performed using Microsoft VSS Snapshot and checkpoint features. When the backup is launched, Veeam Backup requests that a snapshot of the VM be created. This copy becomes the data source for backup. During the first backup, a full backup is performed, thereafter these backups will be of incremental types. Continue reading

Backup ESXi with Veeam

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. Continue reading
