Rclone sync --delete-excluded option


I have rclone to sync with b2 backblaze.

it works great

I have 1 question though.

I have rclone sync a folder which has backup of last 15 days & its gets uploaded to B2. Now on the 2nd day the local folder will only have 15 days worth of files, but i dont want to delete the earlier backed up files to b2. so if i use

rclone sync --delete-excluded option

will it ensure that the 16th day & older files will still remain on b2?

PS: excuse me if i;ve not explained it well…

NM - i have to use copy to maintain files on the destination
