Looking at the summary view, the backup job information is displayed at the top of the form with dates, sizes and colored indicators to tell you if the files were processed.  Green and Green tell you that the files were copied up to the Amazon Servers with success.   The details include size and cost of the transmission.

In the window section called Files Processed, you will get colored indicators about the job.  Please note that 'skipped' means some of the files scheduled to upload, were already there.

The Backazon engine will examine and upload new or changed files in a scheduled job.  When files included in the job are not changed since the last upload, Backazon will 'skip' the file.  This is not an error.  Files that have 'failed' the upload will appear in a Red block color. 

While viewing logs, you can examine any file in detail if a Red failed indicator appears.  Click into List or Tree view to see file details.
