You can check the list of the files in the software. Go to Backup Plans tab, and expand backup plan in question.
There you will be able to see Warning message about files that are about to be deleted.
If you are not able to see this warning please edit backup plan and on step "Retention Policy" please make sure that option "Do not show warning for files to be deleted" is unchecked.
Please let me know if you have additional questions.
Hi there,
If you want to check the list of files that will be purged by retention policy, you should be able to check that in the client.
When the plan finishes, you should be able to see the warning in the backup client, and if you click on it you will be able to check the list of those files to be removed.
Here's how it can look like: http://prntscr.com/l6blgh
