Ok, that makes sence… thank you for your answer. The Dropbox actually does what you says that it ignores the files (it says the file has been changed but in version manager theres not the “newer” version) but anyway the plugin sends the data. I need it to complete the backup.
Is there any place where I could change it manually (e.g.,a file) because it takes too long to backup 5GB website from scratch (I wish I had found and used your plugin since I started to create the site :))
Thanks.
