Restore prerequisites and considerations

Review the following requirements before initiating a restore operation for an OpenStack virtual machine (VM):

Alternate Location Restore: Restores create a new OpenStack VM on the target project/region with customized settings. Direct overwrite of source VMs is not supported.
Destination Project and Region: You can restore a VM to its original OpenStack project or an alternate accessible project/region.
Naming Constraints:
- Restored VM names must contain only alphanumeric characters and hyphens (no spaces or special symbols).
- Maximum VM name length is 63 characters.
- Default restored name format: <sourcevm>_n , where <n> is the next available restored VM name.
Storage and Cinder Volumes: Restored disks are created as Cinder volumes. Ensure target storage volume types have sufficient quota and capacity.
To successfully restore a virtual machine, the target project must have sufficient compute and storage capacity available. The project quota must have:
- Instances (Nova): At least 1 available instance in the quota.
- Compute Resources (Nova): Sufficient available Cores (vCPUs) and RAM in the quota to accommodate the specific flavor selected for the restore.
- Storage Resources (Cinder): Sufficient available storage (gigabytes) in the quota to accommodate the total size of the disks captured in the restore point.
Networking: Select an available OpenStack Neutron network associated with the destination project.

Procedure

Log in to the Management Console.
Navigate to Protect > OpenStack.
In the left navigation pane, select Configured VMs.
Select the virtual machine you want to restore and click Restore.
Select the desired Recovery Point (snapshot timestamp) from the timeline.
Click Proceed to Restore.
In the Full VM Restore window, configure the alternate destination settings. Review the configuration summary and click Finish.

Field	Description
Destination Project	Select the OpenStack project where the restored VM will be created.
Region	Select the target OpenStack region.
Availability Zone (Optional)	Select the target availability zone.
Backup Proxy	Select the active backup proxy deployed in the destination project.
Flavor	Select the target OpenStack compute flavor specifying vCPU/RAM.
Network / Network Port	Select the target Neutron Network (for example, Network 1) or Network Port (for example, NPort 1). 📝 Note Select at least one of Network or Network Port. Selecting neither results in a validation error.
Security Groups (Optional)	Select the target Neutron security groups.
Server Group (Optional)	Select the target server group to which you want to associate the restored vm.
Recovered VM Name	Enter a custom name or accept default. Default: `<sourcevm_n>`, where `<n>` is the next available restored VM name.

Druva orchestrates OpenStack Cinder volume creation, and Neutron port allocation.
Once disk writing completes, Druva automatically powers on the newly restored OpenStack virtual machine instance.
