If you try to do a “rollback” and you encounter the following error:
“Error(s) – See Status Log for details Warning: Unable to create undo script in site root. You will not be able to automated undoing the rollback if something fails so BackupBuddy will not continue. Tried to copy file `…classes/_rollback_undo.php` to `…backupbuddy_rollback_undo-3c6tmgoxra.php`.
You need to make the website folder writeable, at least temporarily by adding the user and permission via the file security tab.
