问题 I am using AWS RDS for MySQL. When it comes to backup, I understand that Amazon provides two types of backup - automated backup and database (DB) snapshot. The difference is explained here. However, I am still confused: should I stick to automated backup only or both automated and manual (db snapshots)? What do you think guys? What's the setup of your own?

问题 I am trying to manipulate db directly from pgAdmin4 but I cannot connect. What I checked and did are I read this doc and following https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ConnectToPostgreSQLInstance.html#USER_ConnectToPostgreSQLInstance.Troubleshooting and input the information about the db instance as the doc does. However I couldn't connect and I checked the security group. The VPC security group is like this. What else should I check? I totally have no idea how I can
