Convert an existing appliance agent to Direct-to-Cloud (D2C)

Overview 


Why switch an agent from appliance mode to Direct-to-Cloud mode? 

It is sometimes necessary or desirable to switch an existing protected system agent operating in the appliance mode to one operating in the Direct-to-Cloud mode. For example: 

  • You may have an aging, on-premise BDR appliance you would like to retire in order to convert a customer from appliance-based backups to Direct-to-Cloud backups. However, the existing backup history already replicated by the appliance to the Cloud vault must not be lost.
  • You may have a customer who has experienced a sitewide disaster, with their server infrastructure virtualized in the Axcient cloud.  To seamlessly continue backups while virtualized in the cloud, you might prefer to convert the agents on the protected systems to Direct-to-Cloud mode, and then attach them to the existing vault backup sets.

What happens during the switch from appliance to Direct-to-Cloud?

During the conversion from appliance mode to Direct-to-Cloud mode, data for the protected system may already exist from a previous appliance replication. The agent now assumes the vault instance and preserves the existing recovery point history. 

Important: A full backup is required when converting an agent from appliance to Direct-to-Cloud (or vice versa.) In most cases, this full backup will be triggered automatically. If the full backup is not triggered automatically, then a full backup should be triggered manually. This is to ensure that critical recovery metadata is generated and fully synced between the server and the protected system.

Note: Although the agent will scan the full contents of the protected system disks during this backup, the data sent to the cloud will be deduplicated and only net-new and changed data will be sent to the vault over the internet. This backup is expected to take somewhat longer than a normal Incremental backup, but typically only by a few minutes. 


A note about full backups in x360Recover

Unlike other backup products, x360Recover does not generate new recovery chains when performing subsequent full backups.

Instead, because of the chain-free nature of x360Recover, the additional full backup simply serves to fully synchronize the protected system with the backup server.  Any data on the backup server which is not different from data on the protected system is discarded and does not cause duplication of storage consumption. 

The agent sends hash data to both appliances and vaults. The hash data used by the agent to determine which blocks that have changed is stored. When a full backup is performed, the hash data from the backup server is downloaded to allow full deduplication of the data  already present on the server. 

When a new full backup is requested, the agent copy of the hash file is deleted and the server-side hash files are downloaded. This serves as the basis for deciding ‘what has changed’ between the last backup on the server and the current protected system. 

Agent hash files are replicated to the vault along with the protected system snapshot data. When converting an endpoint from appliance-based backups to Direct-to-Cloud, the current hash data is already present on the vault.


Steps to convert an existing appliance agent to Direct-to-Cloud

To convert an existing appliance agent to Direct-to-Cloud, perform the following steps: 

1. Verify that no backup is currently running on the appliance.

2. Uninstall the agent from the protected system.

Important: Do NOT delete the agent installation directory or aristos.cfg file.

3. Verify that the appliance has completed replication of all snapshots. The date/time on the most recent snapshot on the appliance should match the most recent snapshot on the vault.

4. Delete the protected system’s replication configuration on this appliance for all vaults it is configured to replicate to. 

Important: Do NOT choose to delete the protected system from the vault.


5. Download the Direct-to-Cloud Windows agent. 

For Direct-to-Cloud, you can find the Windows Agent download link under the Clients tab in the vault:

6. Install the Direct-to-Cloud agent on the protected system. The agent installer should present the parameter configuration screen during installation with the server field grayed out and not available to be selected. For full details on installation, see the Direct-to-Cloud Quick Start Guide

 Important Note: The Direct-to-Cloud agent installation file contains a specially formatted name, including an installation token that identifies which client the agent is being installed for.  Do not rename the agent installation file when downloading it from the vault.

7. Verify that the protected system is registered in the Axcient Cloud: 

  • Open the Protected Systems page on the vault and review the Location column.
    1. If the protected system is on Direct-to-Cloud, it will indicate Axcient Cloud under Location
    2. Additionally, after an end point has been converted to D2C, it will display a Schedule section:



8. Verify that the next backup executed is a full backup. (If this is not the case, click Schedule Now and select Full Backup from the Protected Systems Details page.)

9. Delete the protected system from the appliance and reduce the endpoint licensing assignment  for the appliance in the License Portal. When removing the last protected system from the appliance and retiring it, delete the appliance location from the License Portal to remove it completely from x360Recover Manager. 

Note: It is important to ensure a full backup is performed when converting from appliance to Direct-to-Cloud mode. This is to  ensure the protected system is fully synced with the backup server in the cloud.


Billing considerations

Important: To avoid double-billing for this protected system, you must (a) remove the protected system from the appliance and (b) also remove its license from the client's location in the License Portal.

  • Direct-to-Cloud billing is based on usage. Usage is automatically calculated by the presence of the protected system data on a vault in Direct-to-Cloud mode.
  • Appliance billing is based on License Portal licensing locations. 

NOTE: It is important to  (a) fully delete the protected systems from the appliance and (b) remove the appliance and/or protected systems entirely from the Management Portal. Otherwise, converted protected systems will not be reported properly in the reports - AND YOU MAY BE BILLED FOR BOTH INSTANCES of the protected system. 


Converting a protected system to Direct-to-Cloud mode automatically triggers billing for a new Direct-to-Cloud endpoint. 

Failure to remove either (a) the original License Portal location for the appliance or (b) the licenses assigned to the converted protected systems for this location will result in double billing for that endpoint.  


If you are converting all of the protected systems on a given appliance to Direct-to-Cloud:

  • Delete the location where that appliance is assigned
  • Retire that appliance once you are done converting endpoints to Direct-to-Cloud.

If you are converting only some of the protected systems on a given appliance to Direct-to-Cloud:

  • Reduce the endpoint licenses assigned to the appliance location to match the remaining endpoints on the appliance.  (If the appliance has been assigned a storage license, you do not need to adjust the License Portal configuration.  Your billing will reflect a new Direct-to-Cloud endpoint charge in the next billing cycle.)
