We have just released Syncplify.me Server! v18.104.22.168 to work around the issues caused by CloudBerry Backup, as discussed in this post.
The SFTP protocol standard states “The server will respond to this request with a SSH_FXP_STATUS message. If a file or directory with the specified path already exists, an error will be returned.”; Yet, CloudBerry Backup tries to create the same directory twice and when Syncplify.me Server! correctly sends an error back the second time (because the directory already exists) CloudBerry Backup (22.214.171.124) considers the backup job failed.
This new version of Syncplify.me Server! tries to identify CloudBerry Backup, and sends a “success” reply upon double directory creation requests, but will practically ignore the second request if the first one was successful.
We have already contacted CloudBerry Lab, and we will remove this workaround from our software as soon as they release an update that fixes their protocol violation issue.
For now, if you need to use Syncplify.me Server! together with CloudBerry Backup, you are advised to download the latest version of our server from our web site.
