Support » Plugin: BackWPup - WordPress Backup Plugin » Temp dir not writeable …

  • This plugin worked great on my sites (more than 50) until the WP3.2 update and the switch to BackWPup 2.0/2.0.1. Now I have tried to use it on several of the sites and it does not work. I have to abort the backup, and have started switching my sites to another backup plugin. It’s a shame, because I really liked the old version. It was much simpler, and totally reliable.

    The latest problem I had is trying to use it with a new site, and I get the error Temp Dir Not Writable. I don’t know where to find the temp dir to set the permissions correctly. What should the permission be?

    Thank you,
    How Carson

  • The temp directory is set by your host. Now, if you are the host the tmp directory location can be found in PHP.ini.

    Now, if you are not the host then ask your website host about this. If they fix it, great. If not, you can change the tmp directory WordPress uses by using the command below. Make sure to make a folder in your home directory before doing so.


    I have the same problem and, like the OP, it’s a new one – have never experienced it before. I also don’t see why it should now be an issue having worked fine on many installs before. It is furthermore impractical to create a Temp Dir for each WordPress install (over 200!), and insert the suggested command into the config file of each …

    Please help!

    hi, i red the temp dir form a sys_get_temp_dir() function of php.
    the define in wordpress don’ work with my plugin! you can plase a file named .backwpuptempfolder in the plugins folder to set an other temp dir.
    write only the path in the file.

    If this is the case, I will have to fall back on a previous version of BackWPup that worked …

    There has to be something broken with the plugin and not the site itself.

    I have one hosting server, and several WordPress installs. The plugin works with only one of these WordPress installs. The rest of them I get the “Temp dir not writeable”. Same server, different WP installs.

    I cannot locate any file named .backwpuptempfolder

    Curious observation. The one WordPress installation that this works on is located in a folder named “WordPress”. The other installations are located in folders that have other names. Could that be a problem?

    you must self create the file .backwpuptempfolder only than it will used.

    i’m looking for the problem and test with some people.
