5.3. Using Acronis Storage with Acronis Backup Cloud

The Acronis Backup Gateway storage access point is intended for service providers who use Acronis Backup Cloud and want to organize a storage on their premises to store their clients’ backed-up data.

The Acronis Backup Gateway enables a service provider to easily configure storage for the proprietary deduplication-friendly data format used by Acronis.

Acronis Backup Gateway supports the following storage back-ends:

  • Acronis Storage clusters with software redundancy by erasure coding,
  • NFS shares mounted on nodes in parallel with clusters.

In the latter case, you can use hardware redundancy, e.g. EMC NFS. Acronis Backup Gateway does not provide data redundancy or perform data deduplication itself.

When configuring the Acronis Backup Gateway, you must provide the credentials of your administrator account in Acronis Backup Cloud.

5.3.1. Understanding the Infrastructure

The Acronis Backup Gateway storage access point runs as services on the Acronis Storage nodes. It should be deployed on multiple Acronis Storage nodes for high availability.

5.3.2. Configuring Acronis Backup Gateway Clusters

To set up an Acronis Backup Gateway cluster on top of an Acronis Storage cluster, do the following:

  1. Make sure that the Acronis Backup Gateway network is configured on each node that will run the gateway service.

  2. On the SERVICES > Acronis Backup Nodes screen, select a check box next to each cluster node where the gateway services will run.

  3. Click Create Gateway and This Acronis Storage cluster.

  4. For each node, select the network interface to which the Acronis Backup Gateway network role is assigned. The gateway service will listen on the IP address assigned to this interface.

  5. Click Proceed.

  6. In Tier, select the storage tier that will be used for the object storage. For information about storage tiers, consult Understanding Storage Tiers in the Acronis Storage 2.0 Installation Guide.

  7. In Failure domain, choose a placement policy for replicas. For more details, see Understanding Failure Domains in the Acronis Storage 2.0 Installation Guide.

  8. In Data redundancy, select an erasure coding mode. For more details, see Understanding Data Redundancy in the Acronis Storage 2.0 Installation Guide.

    Note

    1. Redundancy by replication is not supported for Acronis Backup Gateway.
    2. You can later change the erasure coding mode on the Acronis Backup Gateway > Parameters panel.
  9. Click Proceed.

  10. Specify the external DNS name for this gateway, e.g, backupgateway.example.com. Make sure that the required port is open for outgoing Internet connections and incoming connections from Acronis Backup Cloud on each node running the gateway service. Backup agents will use this address and port to upload the backed-up data.

Important

  1. Configure your DNS server according to the example suggested in the management panel.
  2. Each time you add or remove a node to or from the Acronis Backup Gateway cluster, adjust the DNS settings accordingly.
  1. Click Proceed.
  2. In Account Server Name, specify the Acronis Backup Cloud management server address, which matches the account management console address (https://cloud.acronis.com/).
  3. In Acronis Account, specify the credentials of your Acronis Backup Cloud administrator account.
  4. Click Done.

5.3.3. Releasing Nodes Running Acronis Backup Gateway Services

Before releasing a node, make sure that the cluster has enough nodes running the Acronis Backup Gateway service left.

Warning

If the last node running the Acronis Backup Gateway is removed, the Acronis Backup Cloud customers will not be able to use this cluster as a backup storage backend.

To release a node running an Acronis Backup Gateway service from a cluster, do the following:

  1. On the SERVICES > Acronis Backup Gateway Nodes screen, select the checkbox next to the necessary node.
  2. Click Release.

5.3.4. Connecting External NFS Shares through Acronis Backup Gateway

Note

  1. Acronis Storage does not provide data redundancy on top of NFS volumes. Depending on the implementation, NFS shares may use their own hardware or software redundancy.
  2. In the current version of Acronis Storage, only one cluster node may store backups of an NFS volume.

To set up an external NFS share on a cluster node through Acronis Backup Gateway, do the following:

  1. Make sure that the Acronis Backup Gateway network is configured on the node that will run the gateway service.

  2. On the SERVICES > Acronis Backup Nodes screen, select a check box next to the node where the gateway service will run.

  3. Click Create Gateway and Network File System.

  4. Make sure the network interface with the assigned Acronis Backup Gateway network role is selected. The gateway service will listen on the IP address assigned to this interface. Click Proceed.

    ../_images/stor_image56_2.png
  5. On the Volume parameters screen, specify the NFS hostname or IP of the NFS share as well as the name of its volume in the Export name field.

  6. Specify the external DNS name for this gateway, e.g, backupgateway.example.com. Make sure that the required port is open for outgoing Internet connections and incoming connections from Acronis Backup Cloud on each node running the gateway service. Backup agents will use this address and port to upload backups.

    Important

    1. Configure your DNS server according to the example suggested in the management panel.
    2. Each time you add or remove a node to or from the Acronis Backup Gateway cluster, adjust the DNS settings accordingly.
  7. Click Proceed.

  8. In Account Server Name, specify the Acronis Backup Cloud management server address, which matches the account management console address (https://cloud.acronis.com/).

  9. In Acronis Account, specify the credentials of your Acronis Backup Cloud administrator account and click Done.
