Hello all, i have successfully set up a scheduled backup from several TrueNAS folders to my Onedrive cloud space. I have configured "push" and "copy" as it do want the backup to stay fully intact in case for some reason only a part of the files on TrueNAS are accidentally erased.

My question now is if someone has more insights on what the "copy" function does. It states it copies all files from source to destination and if the file exists in the destination folder, it is overwritten. Does this mean that with every scheduled backup all files are copied once again from source to destination overwriting the destination file or are just the files that have changed since the last schedule overwritten?
