i like to backup my linux based NAS (small files like picutres) to an attached USB Disk with FAT32. For this i like to use rsync.
I know, that this will not work correct per default. rsync will sync the files again and again. I found this question and answers: How can I use rsync with a FAT file system?
But, even if I use the
--size-only option, all files are processed again. The log looks like, rsync tries to set permission/ownership on fat32, which will fail.
rsync: chown "<filename>" failed: Operation not permitted (1)
Question is: is there a way to disable the "chown" command?
currently I use the following command:
rsync -a --modify-window=1 --size-only /data/ /mnt/backup/. &
