Hi There
It's Gagan from the BackupAssist team. Thank you for posting on our forum.
Sorry to hear that you've issues with the backup software.
The reason why you are getting BA4800 on BackupAssist v8.1.1 is because there was a Data container update in this version, which could be related to this warning.
You can refer to the following KB article for more details:
http://kb.backupassist.com/articles.php?aid=3314I would recommend you move/ delete the data container, then format the drives and create a new backup job.
In case the new job reports the same issue then I would recommend submitting the diagnostic report for analysis.
To submit the diagnostic report you will need to log in BackupAssist console > Help > Feedback and Support > Contact Support.
We will review the diagnostic report and revert.
RegardsGagan
