BA4809: VHDX Data container cannot mount due to a sparse file

Error code Product Applies to
BA4809 BackupAssist For BackupAssist 9.4.2 or later.

Description

This error occurs when a VHDX Data container is on a destination that changes to a sparse file system. When this happens, BackupAssist cannot mount the Data container.

Resolution

There are two possible resolutions to this problem

Resolution 1 - Turn off sparse files

Turning sparse files off on your NAS device can resolve the problem and allow the System Protection backup to use the NAS as a backup destination.

To learn more, see our Windows Server & Linux NAS Sparse File System guide.

Resolution 2 - Remove the sparse file system

Upgrade the NAS device (firmware or hardware) so that it is no longer a sparse file system. For information on how to perform this task, refer to the NAS device's documentation.

To learn more, see our Windows Server & Linux NAS Sparse File System guide.
