Folders created for individual files
Thanks for providing this information. So if you want to stay on the file-level backup, you can use simple mode. It will just copy what you have on your disk. The simple mode doesn't allow versioning, retention, encryption, compression, etc., but it will back up the latest version of your files, and the backup size should be very close to the size of your source files.
You can switch to image-based backup if you want a system snapshot for full system recovery.
