You need to work out the Recovery Point Objective (RPO) and Recovery Time Objective (RTO) for each of your databases.
Both of these will help you work out the appropriate recovery model and frequency/type of backups required.
... and as Luis mentioned above, you need to automate a restore process to ensure that all the lovely backups you have are actually worth the space they occupy!
Good luck and let me know of you need further help as I went through a similar exercise recently.

It takes a minimal capacity for rational thought to see that the corporate 'free press' is a structurally irrational and biased, and extremely violent, system of elite propaganda.

Society has varying and conflicting interests; what is called objectivity is the disguise of one of these interests - that of neutrality. But neutrality is a fiction in an unneutral world. There are victims, there are executioners, and there are bystanders... and the 'objectivity' of the bystander calls for inaction while other heads fall.
