failing with "Block is not initialized" during incremental backup

Error: Block is not initialized.

Hello.

For the past few days, the backup has not been proceeding due to the error shown above.

I confirmed on forums and communities that this error can be resolved by performing an active full backup. While the active full backup and the subsequent first incremental backup succeed, the same error continues to occur from the next incremental backup onwards, causing the backup to fail.

And I have checked the health of the physical disks on the server, and all disks are confirmed to be in normal condition. There are no hardware-related errors or bad sectors detected.

Also, is there anything else I should check?

Thanks.
