Have you contacted support by opening a ticket?  You can check the logs for Veeam here - C:\ProgramData\Veeam\Backup\JobName

But due to the complexity of this error support will need to be engaged.  The community is not technical support but people that can offer suggestions for issues.

Yes, I have already raised a case with VEEAM. It is taking time. Logs are uploaded.

Ok well continue on with them.  Again this is not a support forum but you can post the issue on the Veeam Forums with your case number to get additional help - https://forums.veeam.com

Sounds good

Hi, I have the same problem. What solution did Veeam provide?

Below are the two issue faced by us and the solutions provided by VEEAM 

This issue happened 3 months back

1. Ran rescan of the "Protection Group", which failed.
2. Checked and found that /opt/veeam/VeeamPluginforSAPHANA/LocalInfo.xml was missing.
3. Created the file manually and backups worked

This issue happen recently.

I have reviewed the logs uploaded and can see the Plugin machine is trying to connect the Repository but the repository has two IP's where x.x.x.x is connecting but the y.y.y.y is not connecting.

--- But the backup every time tries to connect y.y.y.y IP first causing backups to wait 130 seconds for every request and this causes backup not to complete and fail with time out error.

--- To overcome this issue, can you perform below step in the affected SAP Hana machine?
