    Hi,

    I am having a few issues getting one of my client's PBX to backup to FTP correctly.

    When the scheduled backup runs I get the following error:

    When I run a manual backup it will create the file on the FTP server but it will have a file size of 0kb.

    I have several other clients backing up successfully to the same FTP (with the same user credentials) and am able to connect to/write to the FTP from the client's PBX machine though a third party FTP app. This leads me to believe it is not related to any networking/permissions issue between the PBX and the FTP.

    Local backups complete successfully too.

    Does anyone have an ideas on what the issue could be or could point me on a helpful troubleshooting path? My Googlefu has turned up no results.

    Thanks!

    I have studied this and it appears to be a bug. There was a bug in version 15 whereby the initial connection was made to the ftp server and then the backup file was created in /tmp. If the time taken to create this file was greater than the timeout of the server, when the file was ready, the server would have timed out and the backup failed. It seems the fix 3CX employed was to start transferring the file while it is still being created. This invariably fails. I have brought it up on another thread previously and it didn't go anywhere, so I just switched to Google Drive, which is not ideal, but I have a backup.
