Relinking a Backup Job

Relinking allows you to reconnect backup data that was moved, or recreate a completed backup job that was deleted.

Important:

To relink backup data on the cloud, the original backup job must have enabled deduplication.

  1. Open HBS 3.
  2. Go to Backup & Restore.
  3. Click Create, and then click Relink backup job.

    The Relink Backup Job window opens.

  4. Locate your backup data.
    1. Select the storage space where your backup data is located.

      For more information, see Storage Spaces.

    2. Click Select.
    3. Locate and select your backup file.
    4. Click Next.

      A confirmation window opens.

    5. Click Yes.
      Note:

      HBS automatically pairs your backup file to the original source folder on your NAS.

  5. Optional: Specify the job identification information.

    2. Click Enable Version Management.

      Option

      Description

      Simple Versioning

      Retains the specified number of versions.

      • Retained versions: Retains versions until the specified value is reached. Older versions are removed to make space when necessary.

        The maximum number of versions is 65536.

      • Retained days: Retains versions created within the specified number of days. Older versions are removed to make space when necessary.

        The maximum age of retained versions is 3650 days.

      Smart Versioning

      Retains a backup created during a time period for a specified length of time.

      • Retained hours: At the end of every hour, the earliest backup created that hour becomes the hourly backup. The backup is retained for the specified number of hours and then removed.

        Hourly backups can be retained for up to 87600 hours.

      • Retained days: At the end of every day, the earliest backup created that day becomes the daily backup. The backup is retained for the specified number of days and then removed.

        Daily backups can be retained for up to 3650 days.

      • Retained weeks: At the end of every week, the earliest backup created that week becomes the weekly backup. The backup is retained for the specified number of weeks and then removed.

        Weekly backups can be retained for up to 520 weeks.

      • Retained months: At the end of every month, the earliest backup created that month becomes the monthly backup. The backup is retained for the specified number of months and then removed.

        Monthly backups can be retained for up to 120 months.
  9. Optional: Configure the data integrity check settings.
    Note:

    • Data integrity checks ensure backup files are not corrupted so they can be restored correctly. For details, see Data Integrity Check.

    • If version management is enabled, HBS 3 also checks the data integrity of all backup versions where hash values were previously recorded.

    • This feature does not currently support Amazon Glacier, Amazon S3 Glacier Deep Archive, or Azure Archive Storage.

    1. Click Data Integrity Check.
    2. Configure the schedule for quick checks.
      Note:

      Quick checks are not available for NAS-to-NAS backup jobs where the data deduplication feature QuDedup is disabled (see step on configuring job methods).

      Option

      Description

      No schedule (run manually)

      Runs only when a user starts the quick check.

      Run on the following days

      Runs the quick check once per week.

      Run on the following schedule

    3. Optional: Select Content Check.
      Important:

      A content check may download all files temporarily for comparison.

      Some cloud service providers charge additional fees for download traffic.

      Note:

      • Content checks are unavailable for the following:

        • Jobs created in earlier versions of HBS 3 that do not support data integrity checks

        • NAS-to-NAS jobs with QuDedup disabled where HBS 3 on the destination NAS does not support data integrity checks

      • After you enable Content Check for the first time, HBS 3 will continue to record MD5 hash values even if you disable it later.

    4. Optional: Configure the schedule for content checks.
      Note:

      • This option is only available when Content Check is selected.

      • If a quick check and a content check are both scheduled to run at the same time, only the content check will run.
