Description

Gcp vm instance ({GcpVmInstance.InstanceId}) has disks which contain old snapshots that were created more than 90 days ago ({GcpVmInstance.InstanceDisks.Disk.snapshots}). Snapshots incrementally back up data from your persistent disks. After you create a snapshot to capture the current state of the disk, you can use it to restore that data to a new disk. Usually, you're only going to need the most recent snapshot to restore data if something goes wrong.

  Recommended Mitigation

  Cost optimization could be achieved by deleting the snapshots that aren't necessary and were created more than 90 days ago.
