    Hi,
    I’ve made a backup from a site which creates 3 zip files. When I try to restore my site on a new server the third zip gives a Bad File Structure message, I’ve made 3 backups from this site and they all give the error. Also when I try to unzip this file on my desktop it says ‘Unable to expand’. What do you think is going wrong here, what can I do?, the file is only 180MB.
    Thanks

    Just to clarify, I’ve just tried again, I’m getting error: PCLZIP_ERR_BAD_FORMAT(-10): invalid archive structure when uploading the backup even though all 3 files upload 100%.

    Hi @pencilboy

    The error PCLZIP_ERR_BAD_FORMAT(-10): invalid archive structure occurs because the backups were broken in the backup process(mostly becasue of insufficient disk spaces). Please unzip the backups in your local computer to see if they are broken.

    If it can be successfully unzipped, please upload the backups via FTP client to the target site (by default to /wp-content/wpvividbackups folder) then click the “Scan uploaded backups and received backups” button to display them in the backup list and restore.

    If it can not be unzipped, you will need to create a new backup to upload. Before that, please free up the disk space of the source site.

    In general, in order to successfully backup a site, the amount of free disk space on the web server usually needs to be twice the size of the website.

    Kind Regards,
