Planning for SP Timer Job (OOB)

Hi Guys

I have a requirement to plan about an OOB Timer job in SharePoint 2013. 

Purpose – This is going to pull all the data, based on some criteria and going to generate an XML file to a predefined location, in a periodic manner.

Challenge – I need to plan about the exceptions of the Timer job, and various erroneous situations, for this  job. This is a part of my solutioning. 

Could you please suggest, how should I plan for this Timer Job. 

N.B. No scope of VS code deployment.

Thanks for your attention and inputs in advance.
