The One Click Restore will bring back all VMs from the Snapshot in the same state as they were backed up. They will:

• be located in the same cluster in the same datacenter

• use the same storage domain

The Selective Restore is the most complex restore Trilio has to offer. It allows to adapt the restored VMs to the exact needs of the User.

With the selective restore the following things can be changed:

• Which VMs are getting restored

• Name of the restored VMs

• Which networks to connect with

• Which Storage domain to use

• Which DataCenter / Cluster to restore into

• Which flavor the restored VMs will use

                                     <snapshot_id>

required restore.json for CLI

The workloadmgr client CLI is using a restore.json file to define the restore parameters for the selective and the inplace restore.

An example for a selective restore of this restore.json is shown below. A detailed analysis and explanation is given afterwards.

General required information

Before the exact details of the restore are to be provided it is necessary to provide the general metadata for the restore.

• openstackstarts the exact definition of the restore

Selective Restore required information

The Selective Restore requires a lot of information to be able to execute the restore as desired.

Those information are divided into 3 components:

• instances

• restore_topology

• networks_mapping

Information required in instances

This part contains all information about all instances that are part of the Snapshot to restore and how they are to be restored.

Each instance requires the following information

The following example describes a single instance with all values.

'instances':[
  {
     'name':'cdcentOS-1-selective',
     'availability_zone':'US-East',

Information required in network topology restore or network mapping

To activate a network topology restore set:

restore_topology:True

To activate network mapping set:

restore_topology:False

When the network mapping is activated it is used, it is necessary to provide the mapping details, which are part of the networks_mapping block:

Inplace Restore required information

The Inplace Restore requires less information thana selective restore. It only requires the base file with some information about the Instances and Volumes to be restored.

Information required in instances

Network mapping information required

There are no network information required, but the field have to exist as empty value for the restore to work.
