The wp-content/uploads folder is where all your image and media uploads are stored.
By default, WPvivid Backup Pro will back the entire uploads folder up, you can exclude folders/files inside it.
To exclude folders/files, when taking a backup manually or creating a backup schedule, and under the ‘Choose what to back up’ option > Exclude Additional Files/Folder > Select uploads from the dropdown menu > Select folders or files(You can double-click the folders to expand them and show files/folders inside them) > Click Exclude Files/Folders to exclude the selected files/folders.
If you need to back up a custom uploads folder, select it in Additional Files/Folder option.
