Arcserve UDP 11 Integration with Impossible Cloud Storage

This article explains how to configure Arcserve Unified Data Protection (UDP) to copy recovery points and files to Impossible Cloud Storage.

Limitations

  • The integration works only with the on-premises Arcserve UDP Console. It was tested with Arcserve UDP 11. The new Arcserve Console (SaaS and on-premises) does not support the Copy Recovery Points and File Copy tasks that this integration relies on. See the Arcserve Console limitations in the Arcserve documentation.
  • Object Lock is not available for the Amazon S3-compatible cloud service in Arcserve UDP. Immutability cannot be configured from Arcserve UDP for Impossible Cloud Storage.
  • Impossible Cloud Storage is used as a secondary copy target through the Copy Recovery Points and File Copy tasks. The primary backup destination remains a local disk, a shared folder, or a Recovery Point Server data store.

Prerequisites

  • Arcserve UDP 11 installed on-premises, including the Arcserve UDP Console.
  • An access key for a dedicated IAM user. See How to Set Up a Secure Programmatic Access to Impossible Cloud Storage for Backup Applications.
  • A bucket in Impossible Cloud Storage. See Creating a Bucket. Arcserve UDP requires selecting an existing bucket when creating the cloud account, even though Copy Recovery Points writes to a separate bucket it creates automatically (see below).
  • A backup plan with a Backup: Agent-Based Windows task (or another backup task) writing to a local destination.

When you select the cloud account in a Copy Recovery Points task, Arcserve UDP creates its own bucket with the prefix arcserve-<hostname>-. It does not use the bucket entered in the cloud account. The IAM policy of the access key must therefore allow creating buckets (s3:CreateBucket) and access to buckets with this prefix.

Step 1: Add Impossible Cloud Storage as a cloud account

  1. Log in to the Arcserve UDP Console and click the resources tab.
  2. In the left pane, go to Destinations > Cloud Accounts and click Add a Cloud Account.
  3. Enter the following values:
    • Display Name: a unique name, for example Impossible Cloud
    • Cloud Service: Amazon S3-compatible
    • Cloud Endpoint: the endpoint of your region, for example https://eu-central-2.storage.impossibleapi.net
    • Access Key ID and Secret Access Key: the access key of your IAM user
    • Bucket Name: an existing bucket, for example my-backup-bucket. Copy Recovery Points does not write to this bucket.
  4. Leave Connect using a proxy server unchecked unless your server needs a proxy for outbound connections.
  5. Click OK.

Step 2: Add a Copy Recovery Points task to a backup plan

  1. Go to resources > Plans > All Plans, select your plan and open it for editing.
  2. Click Add a Task and select Copy Recovery Points as the Task Type.
  3. On the Source tab, select the backup schedules whose recovery points should be copied, for example Daily Incremental Backup.
  4. On the Copy Settings tab, configure:
    • Destination Type: Cloud Storage
    • Cloud Service: Amazon S3-compatible
    • Cloud Storage: the cloud account created in Step 1
    • Compression: Standard or as required
    • Encryption Algorithm: use this if you want client-side encryption. Arcserve UDP then encrypts the data before uploading it to Impossible Cloud Storage. Select an algorithm and set the Encryption Password. Store the password securely. It is required for every restore.
  5. Optionally, define a time window on the Schedule tab. Without a schedule, the copy starts right after each selected backup.
  6. Click Save.

The cloud account can also be used as the destination of a File Copy task, for example in a separate plan, to copy selected files and folders to Impossible Cloud Storage.
