Duplicator stucks in Step 3 building zip archive

    Hello all,

    I used Duplicator already many times without any problems, last time about 4 weeks ago. But yesterday I got a problem creating an new backup of my site:
    In step 3 – after the progress-dialog shows 58% – the browser-page went white and nothing else happend.
    After a while I re-open the wp-dashbord in a different window, clicked on Duplicator >> Archive. There was an entry showing my new backup at 58% and a size of 100MB (instead of 165MB).

    Log/tracefiles don’t show any error.

    After some tries and errors and “cleaning cache” and “resetting packages” I switched the archive type from ZIP to “DupArchive (beta)” … and succeeded!

    Now my question: What is going wrong, why I get this problem after working for 2 years without any problems, at least 4 weeks ago?

    Thanks a lot!
    Erich

    Hey @erichs,

    If you are on a shared host it could be that your server is hitting resource contention with other sites on the server. The zip archive on lite is single threaded meaning it will only run as long as the server is allowed based on PHP/Apache timeout settings. More details about timeout issues can be found here:

    Hope that helps~

    Hi Cory,

    thanks for your fast reply and your advice.

    But I get no timeout – at least there is no such error on the screen or in the logfile. And: the blank page is displayed very quickly.

    The only thing that has actually helped was to reduce the number of files by excluding the upload directory.
    But why is it not causing a problem using the DupArchive format? Supposed it is really a timeout – is using this format so much quicker? And for haven’t changed the number of files for months (our site is nearly static, no blogs, no comments,..) why do we get suddenly this problem?

    But, o.k., after trying the whole day I will try again tomorrow. Maybe the server have had a bad day ;-(

    Greetings

    The DupArchive format using chunking requests to call to the server so it runs for 15 seconds, dies and starts a new thread this allows it to go on and on without the issue for a server timeout. The ZipArchive is single threaded so it can only run as long as the server is allotting it to run.

    If you want to submit a support ticket for this issue we can have a closer look at your setup. Please provide a link to this thread when submitting the ticket.

    Thanks~
