where are you seeing this message?

this may be a known issue with some customers. I would strongly encourage you to open a support case and send the logs using the tools diagnostic toolbar option on one of the agents that is experiencing the issue. Or, you can send the logs from the Management Console from Remote Management - and click the gear icon and select Send Logs.

Support will be able to recommend a workaround and communicate with you when it will be fixed.

I submitted ticket to support. They came back with some IO issues. I uninstalled and installed and older version. That ran the backup with no issue. Disappointing that I had to go back to older software to get this to work.

Please let them know your results after the version downgrade. They’ll get that info to the engineering team for review and ultimately fix the issue. Thanks for your patience.

I completely removed and reinstalled newest workstation agent on one computer. It still failed. I ended up installing 7.5.3.3 . on each workstation. All the backups completed without issue.
