# Nutanix Volume Groups

## General

Storware Backup & Recovery supports volume groups for the Nutanix platform. Disk snapshots are being attached to the host with Storware Backup & Recovery Node using iSCSI. Thanks to this backups and restores can be performed remotely without Proxy VM.

This storage provider also allows excluding disks for backups.

In general, the export process looks as follows:

* A Snapshot of the volume group is taken
* A Temporary volume group with disk snapshots is created
* Disks from the temporary volume group are attached to Storware Backup & Recovery Node host using iSCSI
* Disks content is exported to RAW files
* Disks are then detached and temporary volume group is deleted

In general, the restore process looks as follows:

* A new volume group is created with yet empty disks
* Disks from a new volume group are attached to Storware Backup & Recovery Node host using iSCSI
* Content from RAW files of backup is imported to attached disks
* Disks are detached from Storware Backup & Recovery Node host

**Note:** iSCSI uses `iSCSI Data Services IP` defined on the Nutanix platform to discover targets, which means that exception will be thrown if this value is missing.
