BackWPup 3.6.1: Bugfixes for a smooth operation

Backup doesn’t handle special characters correctly

When creating the backup archive, some file names were sanitized and in some circumstances this changed the file names and removed diacritics and accents leading to incorrect file names.
Also, sanitizing the file names that contain multiple extensions like “.min.js” were renamed to “.min_.js” for security reasons by WordPress.

We decided that since we cannot know which kind of files the user may have we don’t want to add additional security stuff when we create the backup.
So, now the files are stored in the archive as they are.

Backup doesn‘t override old database file in web root

If you have restored backup files in your root installation after a recently performed restore and you make a backup the database backup file that goes into the backup is the one you have currently in the root directory and not the generated one when you create the backup.

Cannot delete woocommerce_downloadable_product_permissions table

Was not possible to restore a complete database backup because the table `woocommerce_downloadable_product_permissions` depends by another one.
We set the database to not consider foreign key when we perform the restore, this fixes the problem and allows you to import the entire database correctly.
