    • Consolidation is a resource-consuming operation similar to rebackup. Acronis software creates a new consolidated backup from the selected backups by calculating changes through the whole chain, then deletes the selected backups.
    • Consolidation process is a space-consuming operation since it removes initial backups only after the process finishes.

    Known Issues

    Title Status
    Manual consolidation (converting backup to full) fails when it is started on AMS and the backups are located on unmanaged vault. Workaround: run Conversion from the agent
    Consolidation is not possible on tape archives. Backups are marked for deletion instead. This is by design behaviour for backups on tapes


    Follow step-by-step instructions below to troubleshoot the issue. Complete prerequisites step before proceeding to error troubleshooting step.

    1. Prerequisites

    Complete all steps before proceeding to error troubleshooting step.

    1.1 Make sure you are facing consolidation problem

    When Consolidation is configured in retention rules and it fails then you have to localize the problem to a specific problem. Set retention rules to "delete backup older than 90 days" (or some big number) and run the retention rules. If they fail continue with troubleshooting retetion rules.

    1.2 Make sure you have enough space on backup location for consolidation

    Consolidation process will consume a lot of space since it will remove consolidated backups only after the process finishes. Free space should be sufficient to write a new full backup.

    If all steps above have been executed and issue still persists, go to error troubleshooting step.

    2. Error troubleshooting

    Complete all steps before proceeding to collect information step.

    2.1 Corrupted Archives

    Archive contents are read during consolidation and therefore the operation will fail if the archive is corrupted. So please validate the whole archive and refer to Troubleshooting Issues with Corrupt Backups if validation fails.

    3. Collect information

    Collect following information and contact Acronis Support.

    3.1 Step-by-step description of the problem
