[Casper] "du: : No such file or directory" in backup emails

[Thomas Larkin]

Why is the du binary even running is what I would ask?  Is it checking for free disk space before it makes the back up? 

If you run it as admin, anything owned by root will be unaccessible, if you have any weird flags on your files it may be unaccessible, if you run it as root you can generally have it run on any file/directory. 

For example, if I did this 

du -d -x -h / 

with out putting sudo in front of it, everything under /private would tell me I don't have permission to view it.  I think this may be a question for jamf as perhaps du runs to check the current back up paths free space, and if there is enough free space then it creates a back up? 

Or are you running any kind of custom scripts?

If it is a permissions issue who should be the owner?

It looks to me like it is trying to guess the size of a file or directory that it can't, is not there, or doesn't have permission to, ie owned by root.

We have setup the backup schedule in the JSS Setup Utility to send 
emails when the backups are complete.  We also have it set to save x 
amount of days of backups.  But, when the emails come out, under the 
section with the previous backups we see these messages:


du: : No such file or directory2009-07-28_02-00-00.sql.gz
du: : No such file or directory2009-07-24_16-08-05.sql.gz

Is this a bug or are we doing something wrong?  Has anyone else seen 
this behavior?
