Support » Fixing WordPress » BackWPUp Has Warnings and E-mail Error

  • I installed backWPup version 1.3.6 on wordpress 2.9.2. I am hosted on a windows platform. The backWPup tool worked on my local windows box when I requested a database only backup. However when I requested a database and file backup on my hosting provider, the backup failed and provided a log which said this:

    It is strange that the above log said “can not send mail” because nevertheless I did receive the log file by e-mail. That said, backWPup did also create all the .gz files it listed with [warning] statements above. If it had permission to create those files, I’m not sure what other permissions it lacked. Also, I don’t know why it made so many .gz files. Shouldn’t there be only one backup file? And why did it make .gz files, when instead I had requested a zip file?
    I figure I’ve simply done something wrong, and I hope there is a simple answer. Any help?

  • I have an update on this item. I don’t know why, but the 2nd time I attempted a backup, it worked. Or at least it performed the database backup and gave much less warning messages. Unfortunately, no files were backed up, even though they were supposed to be included. Here is a link to the log output:

    There are only a few warnings, and one error about using the e-mail function. Can someone explain what might be causing the warnings and the error?

    The link to the original log file I had from November, which had many warnings and I pasted in my first post, is found here:

    Strange, I am getting the same error. Manual backup does not contain any errors, but the automated backups do and in fact the automated backup is no longer running either. The only changes I made was to check the ‘data optimization and database tables’ check boxes in the backup job’s settings, and that of installing wp super cache; before that those errors were not there!
