GCP cloud SQL - Restore to a different instance on different project

Google Cloud Database
1

Hello,

Seeing errors when restoring a backup of MySQL instance to a different instance on a different project

gcloud sql backups restore 1714096800000 --restore-instance=algn-dr-instance-clone1 --project nprd-dr-alignedth-01 --backup-instance=algn-db-01-instance
All current data on the instance will be lost when the backup is restored.

Do you want to continue (Y/n)? Y

ERROR: (gcloud.sql.backups.restore) HTTPError 400: Invalid request: Source instance does not exist.

Can someone suggest on how to resolve this error.

Hello @riyer1 ,Welcome on Google Cloud Community.

According to the documentation, you should use [1]REST option to restore SQL backup from one project to another.
SO basically, you must:

  1. create at the target project SQLInstance
  2. Obtain SQLInstance ID ( in other words, SQL Instance name )
  3. Run following command to obtain backupID
curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  "https://sqladmin.googleapis.com/sql/v1beta4/projects/SOURCE_PROJECT_ID/instances/SOURCE_SQL_INSTANCE_NAME/backupRuns"
  1. You will get output similar to :
damian_sztankowski@cloudshell:~ (projecta-421511)$ curl -X GET      -H "Authorization: Bearer $(gcloud auth print-access-token)"      "https://sqladmin.googleapis.com/sql/v1beta4/projects/projecta-421511/instances/testprojecta/backupRuns"
{
  "kind": "sql#backupRunsList",
  "items": [
    {
      "kind": "sql#backupRun",
      "status": "SUCCESSFUL",
      "enqueuedTime": "2024-04-29T04:37:55.560Z",

      "selfLink": "https://sqladmin.googleapis.com/sql/v1beta4/projects/projecta-421511/instances/testprojecta/backupRuns/1714365475560",
      "location": "us",
      "backupKind": "SNAPSHOT"
    },
    {
      "kind": "sql#backupRun",
      "status": "SUCCESSFUL",
      "enqueuedTime": "2024-04-29T04:35:30.777Z",
      "id": "1714365330777", <- backup ID ( will be needed )
      "startTime": "2024-04-29T04:35:30.804Z",
      "endTime": "2024-04-29T04:37:02.218Z",

      "description": "Backup automatically created after creating an instance with PITR enabled",
      "windowStartTime": "2024-04-29T04:35:30.777Z",

      "location": "us",
      "backupKind": "SNAPSHOT"
    }
  ]
}
  1. Create request.json file and provide info:
{
  "restoreBackupContext":
  {
    "backupRunId": 1714365330777, <- This backup will be restored at another project
    "project": "projecta-421511", <- source project
    "instanceId": "testprojecta" <- source INSTANCE SQL NAME
  }
}
  1. Execute following command to trigger restore
curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://sqladmin.googleapis.com/sql/v1beta4/projects/TARGET_PROJECT_ID/instances/TARGET_SQL_INSTANCE_NAME/restoreBackup"

COmmand should send similar output :

damian_sztankowski@cloudshell:~ (projecta-421511)$ curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://sqladmin.googleapis.com/sql/v1beta4/projects/project-b-421511/instances/tetsprojectb/restoreBackup"
{
  "kind": "sql#operation",
  "targetLink": "https://sqladmin.googleapis.com/sql/v1beta4/projects/project-b-421511/instances/tetsprojectb",
  "status": "PENDING", <- it means that restore has been started
  "user": "damian.sztankowski",
  "insertTime": "2024-04-29T04:56:18.903Z",
  "operationType": "RESTORE_VOLUME",
  "name": "d320975e-6032-4b72-b7dd-afb000000032",
  "targetId": "tetsprojectb",
  "selfLink": "https://sqladmin.googleapis.com/sql/v1beta4/projects/project-b-421511/operations/d320975e-6032-4b72-b7dd-afb000000032",
  "targetProject": "project-b-421511
  1. GO to TARGET PROJECT → SQL → Backups. Wait until restore will end.

Important: The user restoring to a different project must have the cloudsql.instances.restoreBackup permission for the target project and the cloudsql.backupRuns.get permission for the source instance. These permissions are included in the Cloud SQL Admin role.
