Hi all,
we are backing up two physical servers over a wan with two meraki MX-84 appliances between two sites and 100Mb/s fiber
line. With a smaller in size domain controller back up we have no issues, however a larger 2008 R2 SQL Server drops
netwrok connection. Happened twice in arrow, first time at 138Gb and 6:36:38 job run time and the second time at 118Gb
and 05:35:15 job time. I have updated the agent to match the version of the Veritas 16 on the 2008 R2 we are backing
up and installed all the latest updates on the BE 16 Server. Could somene help please to find out what could be the
cause of "The network connection to the Backup Exec Remote Agent has been lost. Please check for network errors".
The event viewers on both hosts have no netwrok related errors of any sort.
Thank you!

I figured it out, we have a policy in our domain that blocks power shell access, it is enforced by a third party via Carbon
Black AV mgmt console. I noticed in the event viewer in the application logs that beremote.exe was blocked from accessing
the PS 3-5 minutes before each time backup would fail. Placing the server in a policy that allows the invocation and
execution of PowerShell solved the issue.
Thanks

It could be those devices disrupting the connection due to KeepAlivetime settings
Can you create a dword "KeepAliveTime" and set it to decimal value 5000 , reboot the BE server and check if it helps

Same error E00084F8 - The job failed with the following error: The network connection to the Backup Exec Remote Agent has been lost. Check for network errors.
Stopped this time at 208Gb, about 1/3 of the full backup. Any other suggestions?
Thanks!
