推荐答案

Q1. Can I change for a daily backup without the need of an initial full backup?

Ans: Yes, you can reschedule the backup without initial full backup. When a new policy is applied, schedule and retention of the new policy is followed. If retention is extended, existing recovery points are marked to keep them as per new policy. If retention is reduced, they are marked for pruning in the next cleanup job and subsequently deleted.

Q2. Is the retention policy configured correctly? do I need to select Monday and Wednesday on the weekly retention policy?

Ans: It’s completely depends on your requirements. Refer the below documentations for more information: 
Backup and retention

Create the backup policy.
