Releasing nodes from backup storage

Backup storage is connected to one specific backup destination. If you need to switch the destination, for example, from a public cloud to a local storage cluster or one public cloud bucket to another, you need to delete the backup storage by releasing all of its nodes from the backup storage cluster and create a new one.

When the backup storage is deleted, it is also unregistered from your Acronis backup software, which loses access to the backup destination.

Limitations

If you choose a forcible release and keep Backup Gateway registered in your Acronis backup software, next time you will need to register another gateway in your Acronis backup software. For that, you will have to delete and recreate not just the backup storage but also the entire storage cluster.

Prerequisites

The backup storage cluster is created and registered in the Cloud Management Panel, as described in Provisioning backup storage space.

To release a node from backup storage

Admin panel

Go to the Storage services > Backup storage > Nodes screen.
Click a node to release, and then on the node right pane, click Release.
Click Release in the confirmation window.

The backup storage will remain operational until there is at least one node in it.

Command-line interface

Use the following command:

vinfra service backup node release --nodes <nodes>

--nodes <nodes>: A comma-separated list of node hostnames or IDs

For example, to release the node with the ID 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb from the backup cluster, run:

# vinfra service backup node release --nodes 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb
+---------+--------------------------------------+
| Field   | Value                                |
+---------+--------------------------------------+
| task_id | ea09642c-291c-4df8-87a5-a8958d6308c1 |
+---------+--------------------------------------+

To release all nodes from backup storage

Admin panel

Go to the Storage services > Backup storage > Nodes screen.
Select all of the backup nodes or click the only node in the backup storage cluster, and then click Release.
In the Release nodes window:
- Select (Recommended) Gracefully to delete Backup Gateway from the node and unregister it from your Acronis backup software.
- Select Forcibly to delete Backup Gateway from the node but do not unregister it from your Acronis backup software.
  
  Select this option only if you are sure that the gateway is already unregistered from your Acronis backup software.
If you chose a graceful release, specify the credentials of your administrator account in your Acronis backup software.
Click Release.

Command-line interface

Use the following command:

vinfra service backup cluster release [--reg-account <reg-account>] [--force] [--stdin]

--reg-account <reg-account>: Partner account in the cloud or of an organization administrator on the local management server
--force: Release the backup cluster but does not unregister it from your backup software.

Choose this option only if you are sure that the cluster has already been unregistered from your backup software.
--stdin: Use for setting registration password from stdin.

For example, to delete the backup cluster with all its data and unregister it from your backup software, run:

# vinfra service backup cluster release --reg-account account@example.com --stdin

Specify the registration password when prompted.
