Correct Answer is (B): Creating scheduled snapshots for persistent disk This document describes how to create a snapshot schedule to regularly and automatically back up your zonal and regional persistent disks. Use snapshot schedules as a best practice to back up your Compute Engine workloads. After creating a snapshot schedule, you can apply it to one or more persistent disks. https://cloud.google.com/compute/docs/disks/scheduled-snapshots

Definitely B. With something like this, you should not have to write any custom scripts, custom functions, or cron jobs. This is google's way of saying 'hey, we've already built that stuff in to our snapshot schedules feature.

Selected Answer: B
I think when we think about best practice, we should always think about being practical. The most practical method is usually the best practice with a few exceptions. In this scenario, Answers C and D require a lot of effort. Answer A seems not quite relevant. Answer B is the only correct option.

B is the best option so far. However just wonder this: Schedule frequency: Daily " Start time: 1:00 AM " 2:00 AM" Autodelete snapshots: after 30 days; For Saturday and Sunday it will be a waste of resource to create snapshots since the instance is running during weekdays.

B. 1. In the Cloud Console, go to the Compute Engine Disks page and select your instance's disk. 2. In the Snapshot Schedule section, select Create Schedule and configure the following parameters: "" Schedule frequency: Daily "" Start time: 1:00 AM "" 2:00 AM "" Autodelete snapshots after 30 days
