WordPress Core File Folder Missing in Backup
-
It appears this issue is wide spread, and I did not want to bury this in a past post, so I am posting a-new here and in detail.
This is what I found,
ZIP Archive
BackwPup did archive the entire WP site, with the core folders, uploads, theme folder, plugin folder etc and root files, but…Viewing Archive
Windows ZIP utility – to view the ZIP archive, WP root files were missing. The WP core folders and all other folders/files were there, but not the WP root files as “wp-config.php” etc.7-Zip – to view the ZIP archive, there was a folder named “.” (yes, just a period for a folder name) and that contained the root files of the WP website. This “.” folder was not visible using the Windows zip utility to view it.
Tar / Tar.Gz / Tar.Bz2 Archives
7-Zip – viewing the archives, there were only the root files. These archive formats failed to archive the rest of the WP site as core folders etc.Extracting – ZIP
Windows Zip Utility – failed to extract the WP root files. It did
extract the WP core folder and all other folders and files. I believe this is because it could not see the “.” named folder that the plugin created to store the root files.7-Zip – extracted the root files and all other folders and files of the WP website. This is likely because it was able to see the “.” named folder.
Extracting – Tar
7-Zip – extracted only the root files, WP core folders and all other folders and files were missing. 7-Zip extraction also showed an error,"Headers Error Warnings: There are some data after the end of the payload data"
Extracting – Tar.Gz
7-Zip – extracted to a .tar archive. Extracting the .tar archive created an extension-less file and generated an error,"Warning: Can not open the files as [tar] archive The file is open as [gzip] archive"
Opening the extension-less file (like an archive) extracted the root WP files but the WP core folders and all other folders and files were missing. 7-Zip generated an error,
"Headers Error Warnings: There are some data after the end of the payload data"
Another problem, the extraction created a duplicate “wp-config.php” file for some reason.
Extracting – Tar.Bz2
7-Zip – extracted as a .tar archive. Extracted the .tar archive which gave the WP root files, but missing were WP core folders and other folders and files.Same other problem, the extraction was creating a duplicate “wp-config.php” file for some reason.
Settings
BackwPup settings was set to include all WP Website folders and files, which means that any of the archives were suppose to be useable to re-install the website in its entirety if needed, but above shows this is not the case.Conclusion:
The plugin has erred a lot here. It creates a ZIP archive that Windows cannot read properly and creates the other archive formats missing a lot of folders and files.
