In the Navigation pane, click Create Backup Job. |
2 |
In Job Name, specify a name for the job. |

4 |
In the list of plug-ins on the NetVault Backup Selections page, open Hyper-V Plugin, and expand the localhost or <clusterName> node to display the list of VMs. |
5 |
Select the localhost or <clusterName> node to include every VM that exists at the time of backup, or select individual VMs to back up a specific set of VMs. |
6 |
The next step involves creating the Backup Options Set or selecting an existing one.
There are multiple options available: Maximum Number of Parallel Streams, Enable indexing for File Level Recovery, Enable Active Block Mapping, and Type of backup.
• |
The default for Maximum Number of Parallel Streams is 4 for Windows Server 2012, 2012 R2, and 2016, and 1 for Windows Server 2008 R2. If your environment uses Windows Server 2012, 2012 R2, or 2016, you can increase the setting up to 32. |
• |
The Enable indexing for File Level Recovery option is disabled by default. Indexing lets you restore individual files and directories from image-level backups of VMs. |

The Enable Active Block Mapping option is enabled by default. To reduce network and storage requirements, ABM technology provides filters to remove zeroed blocks during backups. Removing these blocks reduces the backup size and the amount of data transferred over the network. If you disable ABM, the plug-in automatically uses zero-block exclusion to ensure that the zeroed blocks are excluded during backups. |

The Type of backup section is available if the Backup Selection Set is based on a Windows Server 2016 host or cluster. Because the plug-in uses RCT to ensure that only changed blocks are sent to the Incremental Backup stream, you can indicate whether you want to complete a Full or Incremental Backup. A Full Backup performs a complete backup of the set of items that have been selected. A Full Backup does not depend on any other backup and can be restored in a single step. An Incremental Backup backs up the set of items that have been selected since the most recent Full Backup or Incremental Backup. |

2 |
In the Maximum Number of Parallel Streams box, enter the applicable number. |
3 |
If you might want to perform restores at the file level, select the Enable indexing for File Level Recovery option. |
4 |
If you want to disable ABM for any reason, clear the Enable Active Block Mapping option. |
5 |
If your environment uses Windows Server 2016 or later, in the Type of backup section, select either Full or Incremental, whichever is applicable. |
