Back-up SDDC manager to remote SFTP fails

[Tom van Remoortere]

Hi,

When performing a file based back-up of our SDDC manager it fails with message: 'Failed to send file to remote location'.

The SDDC Configuration and SDDC Database back-ups complete successfully on the same location (see below).

Further, the same external SFTP server is also used  for the file based back-up of my VCSA, which has no issues.

1. 1. Check network connectivity: Ensure that the SDDC Manager instance can reach the remote location and that the network configuration is correct. Try pinging the remote location from the SDDC Manager instance to verify connectivity.
2. Verify remote location credentials: Double-check the credentials used for the remote location are correct and do not have any special characters (e.g., !, @, #, etc.) that might cause issues.
3. Check the remote location's capacity: Ensure that the remote location has enough space to store the backup files. If the remote location is full, the backup will fail.
4. Test a single file transfer: Try transferring a small file from the SDDC Manager instance to the remote location using a protocol like SCP or FTP. If the transfer fails, it could indicate a local or network issue.
5. Check SDDC Manager logs: Review the SDDC Manager logs for any relevant error messages that might provide more information about the failure.
6. Disable any anti-virus software: Temporarily disable any anti-virus software installed on the SDDC Manager instance to rule out any interference with the backup process.
7. Re-try the backup: Try re-running the SDDC Manager file-based backup with the default settings to see if the issue persists.
8. Check for firewall rules: Ensure that there are no firewall rules blocking the SDDC Manager instance from connecting to the remote location.

This may occur when the user used for the FTP configuration does not have SSH access or the SSH service on the FTP appliance is not enabled.

Ensure the the SSH service on the FTP appliance is enabled and started and the user defined is allowed SSH access. 

Check if the backup port is configured to Port 22. SDDC Manager backup only functions on Port 22.

Also, To workaround the issue,  follow the below mentioned steps:

1. Rename the /opt/vmware/vcf/sddc-support/status.json (or status-tmp.json) to something else.

2. Restart the SoS rest service - systemctl restart sosrest.service.
