Offloading to Object Storage Fails With: Backup file version mismatch: scale-out backup repository rescan is required. 

SOBR Offload task fails with the error:

Error: Backup file version mismatch: scale-out backup repository rescan is required.

How to Rescan the Scale-Out Backup Repository

1. Disable all jobs that are targeting the Scale-Out Backup Repository
2. Ensure no Offload tasks are running for the Scale-Out Backup Repository
3. Configure a Capacity Tier Window to prevent offloads from occurring
   If a custom window is configured, take a screenshot of it before setting Denied to all time periods to make it easier to revert later in the steps.
   
   1. Edit the Scale-Out Backup Repository
   2. Go to the Capacity Tier tab
   3. Click the hyperlinked word after "Offload window:" ( Any time / Restricted )
   4. In the Time Periods window that appears:
      1. Click Denied on the right side.
      2. Highlight all time periods.
      3. Click Permitted, and select a single time slot 2 hours before now. (This will prevent offload from occurring for the largest amount of time.)
         
      4. Click Ok
   5. Click Finish to save the settings for the Scale-Out Backup Repository.

4. Wait 5 minutes to allow backend tasks to complete.
5. Rescan the Scale-Out Backup Repository.
