  Go to, Local Security Policy --> Security settings --> Local Policies --> User Rights Assignment --> Back up files and directories and add the Logon user (DomainName\TestFailover)

  

  To add the User in Restore files and directories,

  Go to, Local Security Policy --> Security settings --> Local Policies --> User Rights Assignment --> Restore files and directories and add the Logon user (DomainName\TestFailover)

  

  Possible Reasons for File Synchronization Failure:

  File synchronization between primary and secondary servers can fail due to configuration errors, permission issues, or network connectivity problems. To resolve this, ensure that both servers are properly configured, have the necessary permissions, and can communicate effectively over the network. Below are the specific checks and troubleshooting steps for Windows and Linux setups:

  For Windows

  1. Verify that the Windows share name matches the <OpManagerHomePath>:

     For example,

     • For Essential Setup: \\PEER_SERVER_HOST\OpManager
     • For Enterprise Central Setup: \\PEER_SERVER_HOST\OpManagerCentral
  2. Confirm that all required steps for Windows sharing are correctly implemented. Refer to the instructions here.
  3. Check network accessibility:
     • Access the peer server <OpManagerHomePath> from the current server using the network path.
     • Ensure you have read and write permissions for the shared folder.
  4. Validate credentials:
     • Verify that the credentials stored in Windows Credential Manager are correct and have the required permissions. (Applicable only for the Old Model Failover setup.)

  For Linux

  1. Ensure SSH authentication is configured correctly:Follow the steps detailed here.
  2. Test password-less SSH access:
     • Use the command: ssh <PRIMARY_HOST_NAME> from the secondary server and vice-versa to confirm SSH functionality.
  3. Check network connectivity between the servers:
     • Use tools like ping or telnet to verify the connection.

  If the Issue Persists

  If the problem remains unresolved, please contact support and provide logs from both the primary and secondary servers for further assistance.
