Scale-out Backup repositories
Data locality or performance mode?
Since the introduction of Fast Cloning on ReFS and XFS the Data locality mode is the recommended setting for most deployments due to the space savings and efficiency of synthetic operations. The performance mode is only recommended for very specific use cases.
SOBR Free Space Calculation
Free space data is only retrieved when no active tasks are assigned to an extent. In environments where tasks are always running the estimated capacity may differ from the free space. This may result in an error that there isn’t sufficient space.
To resolve this, you can update another registry key making the checks time-based.
