Uploading Error (3 posts)

    Long time Windows guy playing around with a Mac in a mixed environment. I am uploading to a NAS (D-Link DNS-323)and am intermittantly getting the error "cannot open data connection". If I close out fetch and reopen, I can continue uploading until the error occurs again. Although the uploads are completing fine, it's rather annoying as I am moving a large amount ( ~90GB) of data from a external drive to the NAS.

    Have researched the message boards with little success on this subject.

    Thoughts/Advice?

    Thanks in advance.

    Hi,

    Unfortunately, problems with a server dropping the connection as you are rapidly moving many small files is a somewhat common problem that doesn't have a specific solution. Our best guess is that the rapid fire transfer of files using the FTP protocal eventually confuses either the server's software, or the router between your Mac and the server.

    You should look into whether the NAS supports uploading via SFTP instead of FTP instead; SFTP usually does not experience these dropped connection problems.

    Otherwise, you might want to give the Fetch Mirror command a try (if you aren't already). The Mirror command only uploads new and changed files, so files that have already been uploaded successfully won't be uploaded again. It will figure out where to pick up the upload after the last one left off. Of course, you do have to keep re-running the Mirror command, which I realize isn't so convenient, but it may be quicker than trying to figure out where you left off yourself.

    See the Mirroring a local folder to a remote folder help topic in Fetch Help (or click on the link) for more information about the Mirror command.

    Sorry not to have a better answer for you, and please let us know if you have further questions.

    Thanks,

    Scott McGuire
