Server Backup Failing to due to Read / Write Errors
Description of our problem:
I have 1 Agent Managed Server that fails its backup to the Dedupe Storage Device about 1-2 times per week. All Other Agent Managed Servers are not having this issue. The problems are always related either one of two errors: Error to either Read or Write data to Media. I am including screen shots of each error along with Windows Event Logs for each error off of the Media Server. No logs are available from the actual Agent Managed Server.
Also, there are no errors showing on our Dedupe Storage Device and all other Servers are backing ok.
