New to rsync here. I used it to backup files on an external drive on my home drives. My rsync line is :
sudo rsync -vv -rP /inputFolder ~/backupFolder
I did 2 backups back to back to verify if rsync backed up only files that had been modified, as I understood from what I had read. But to my surprise, the second backup took as much time as the first one, even though no files had changed between both backups.
Important note: the backup is on a samba network drive.
Shouldn't the second backup been much faster since no file had changed since the first one?
