Smart update copying all files each time

[fabius]

Here you go:

$ ls -l /Volumes/Music/iTunes/iTunes\ Music/ACO/Unknown\ Album/Creep.mp3 
-rw-r--r--   1 phil  staff  6193130 Apr 30  2004 /Volumes/Music/iTunes/iTunes Music/ACO/Unknown Album/Creep.mp3
$ sudo ls -l /Volumes/Music/iTunes/iTunes\ Music/ACO/Unknown\ Album/Creep.mp3 
-rw-r--r--   1 unknown  unknown  6193130 Apr 30  2004 /Volumes/Music/iTunes/iTunes Music/ACO/Unknown Album/Creep.mp3
$ ls -l /Volumes/Music\ Backup/iTunes/iTunes\ Music/ACO/Unknown\ Album/Creep.mp3 
-rw-r--r--   1 phil  staff  6193130 Apr 30  2004 /Volumes/Music Backup/iTunes/iTunes Music/ACO/Unknown Album/Creep.mp3
$ sudo ls -l /Volumes/Music\ Backup/iTunes/iTunes\ Music/ACO/Unknown\ Album/Creep.mp3 
-rw-r--r--   1 unknown  unknown  6193130 Apr 30  2004 /Volumes/Music Backup/iTunes/iTunes Music/ACO/Unknown Album/Creep.mp3

OK, that's what I thought you'd see -- those files are all floating, which is why you're seeing them change ownership when you run with and without sudo.

What's weird is that chowning them didn't chown -- which leads me to believe you didn't do it quite right.

So, do the following:

sudo chown -R phil:staff /Volumes/Music/iTunes/*
sudo chown -R phil:staff /Volumes/Music\ Backup/iTunes/*

Then, restart and give the backup another try.

That worked a treat! Thanks so much - super quick!

However, I'm having a similar problem with backing up my main drive - a few files always seem to be copied to the backup drive no matter what. I can do a backup only seconds after the last one finished and it'll still take 12-15 minutes to complete...

If you look at your SuperDuper!.log after one of these "seconds after" backups, how many files does it say it has copied? (Look at the number of files, NOT the size.)

Looks like 8,526...?

More like 622. (The 7866 symlinks need to be copied every time.)

Is it pretty consistently 622? Those are going to be terribly difficult to find, though they're likely in your Home folder. We can try the same chown trick there, if you'd like...
