The case looks like this:
In the program settings – jobs – I have job – backup daily.
Inside this job we have options files – Folders to backup and several options – Folders to backup. I mark Backup uploads folder /wordpress/wp-content/uploads and next Exclude a few folder (2014,2015,2016,2017). This few exclude folder I mark.
So, Up to version 3.4.0 all this exclude folder were not copied – backup size is 48 MB. And after that version is installed, these folders copy and I have 1.2 GB backup. This is problem.
Yesterday I discovered that version 3.4.0 is backup files from excluded folders.
Is a bugs this version ?
Thanks for looking and check this.
