+To restore a share on a Filestore instance on GCP, we start by following the
+documentation linked above. In short, this involves:
 
 1. [Go to the Filestore instances page](https://console.cloud.google.com/filestore/instances) in the GCP console
-1. Click the instance ID of the Filestore you want to restore and click the "Backups" tab
-1. Locate the backup you want to restore from (most likely the most recently created), and click (...) "More actions"
-1. Click "Restore backup" and then select "Source instance"

+Once this is done, you should also set the terraform variable `source_backup` to
+reference this web console change. Practically, you should configure something
+like below in the `terraform/gcp/projects/$CLUSTER_NAME.tfvars` file:
+
+```
+filestores = {
+  "filestore" : {
+    # ...
+    source_backup : "projects/<gcp project name>/locations/<filestore region>/backups/<backup name>",
+  },
+}
+```
+
+You can determine the value of `source_backup` by trying a `terraform plan`
+which should present the value in an associated error.
