We have veeam backup job running and retention period is 14 days. However I see there is data for the backup job for over 20 days. What file is missing from the backup file list that is causing this issues. 

Anything you can see that is missing?

This very well may be accurate because of the job Mode you're using. Are you taking occasional Full backups? Synthetic or Active in your Storage section > Advanced area? If so, you're running Fwd Incremental and your job has to retain older backup files to meet your retention. You need all files in a chain to perform restore operations.

You can review the retention settings for Veeam and there are links to each job type at the bottom of this page as well - Short-Term Retention Policy - User Guide for VMware vSphere (veeam.com)

Veeam has a great KB post animating how retention works. Good stuff! See the links at the bottom for each method.

More than likely this is as it should be, but it would be helpful if we saw what your retention policy is.  I’m confused as to why there are two full backup files on the 13th, and then only 4 incrementals, no backups on the 17th or 18 (failures?), etc. Also, if your keeping only 20 days of backups, but you have GFS retention such as keeping monthly backups for a set amount of time, etc, then it’s going to need to keep more restore points than what you have configured in order to keep a valid backup chain to transforming into those restore points assuming synthetic fulls, etc.  It’s hard to fully know what is going on here without seeing the job logs, backup retention policies, etc.  In general, I don’t get to concerned about the actual backup files though as long as I’m seeing successful backups and restore point maintenance.  And as long as you’re not looking at this due to space issues, etc.

Looking at this, and the dates, this looks right. 14 days is the minimum retention. You can’t have an incremental without the active full.  I don’t know all your settings, but others have posted the retention policies and how they work.

As an example, If I ran a weekly full with incremental, and my retention was set to 8 days, Even on the 9th day running this job it can’t just delete the active full from day one or that whole week would be invalid and I’d only have 2 valid restore points.
