Thanks for feedback.
After doing a little bit research I found that the application (Apache Tomcat) and backup (Veritas NetBackup) was running during the copy job.
What influence have a running Tomcat and NetBackup on rsync? What rsync (running as root) do if there are read-only files?
That's generally not a problem, but you'll get a snapshot of changing files, like growing logfiles, and if a file is deleted while still open it will still consume space on the source as seen by 'df' until the application closes it or exits but it won't be copied.
