Create and manage backups

This page describes Spanner backup operations and explains how to back up a database. For more information about backups, see Backups overview.

You can back up databases using the following:

• The Google Cloud console.
• The Google Cloud CLI.
• The client libraries.
• The REST or RPC APIs.

Before you begin

• The gcloud CLI examples on this page make the following assumptions:

  • You have already set up gcloud CLI for use with Spanner. If you are new to using gcloud CLI with Spanner, see Getting started with Spanner using gcloud CLI.

  • You have configured gcloud CLI with your project. For example:

    gcloud config set core/project PROJECT_ID
    

  • You have an instance named test-instance and a database named example-db.

• To get the permissions that you need to create and manage backups, ask your administrator to grant you the following IAM roles on instance:

  • Create, view, update, and delete backups: Cloud Spanner Backup Admin (roles/spanner.backupAdmin)
  • Create and view backups: Cloud Spanner Backup Writer (roles/spanner.backupWriter)
  Note: IAM basic roles might also contain permissions to create and manage backups. You shouldn't grant basic roles in a production environment, but you can grant them in a development or test environment.

Create a backup

Console

1. In the Google Cloud console, go to the Spanner Instances page.

   Go to Instances

2. Click the instance that contains the database that you want to back up.

3. Click the database.

4. In the navigation pane, click Backup/Restore.

5. In the Backups tab, click Create backup.

6. Fill out the form, and click Create.

To check the progress of a backup operation, see Check the operation progress.

Note: The Google Cloud console doesn't support scheduled or recurring backups, but you can build that capability by using the Cloud Spanner API in conjunction with other services like Cloud Scheduler. For an example, see the Create Spanner Scheduled Backups blog post from the Google Cloud Community.

gcloud

To create a backup named example-db-backup-6 and have it expire in 1 year, use gcloud spanner backups create:

gcloud spanner backups create example-db-backup-6 --instance=test-instance \
   --database=example-db --retention-period=1y --async

Here are some usage notes:

• To set the backup's expiration date, specify either the --retention-period or --expiration-date flag. For information on date syntax, see gcloud topic datetimes.
• The name of the backup must be unique in the instance.
• The command returns immediately because of the --async flag. Without the flag, the command will wait for the backup operation to complete.
• Specify the --help flag to get help for any command.

The output looks similar to the following:

Create request issued for: [example-db-backup-6]
Check operation [projects/my-project/instances/test-instance/backups/example-db-backup-6/operations/_auto_op_234567] for status.

To check the progress of a backup operation, see Check the operation progress.

Client libraries

The following code sample creates a backup at a specific version_time and then waits for it to complete. Once complete, it verifies that the backup is ready and retrieves some information about it, such as its name, size, and create time.

C++

void CreateBackup(google::cloud::spanner_admin::DatabaseAdminClient client,
                  std::string const& project_id, std::string const& instance_id,
                  std::string const& database_id, std::string const& backup_id,
                  google::cloud::spanner::Timestamp expire_time,
                  google::cloud::spanner::Timestamp version_time) {
  google::cloud::spanner::Database database(project_id, instance_id,
                                            database_id);
  google::spanner::admin::database::v1::CreateBackupRequest request;
  request.set_parent(database.instance().FullName());
  request.set_backup_id(backup_id);
  request.mutable_backup()->set_database(database.FullName());

      expire_time.get<google::protobuf::Timestamp>().value();
  *request.mutable_backup()->mutable_version_time() =
      version_time.get<google::protobuf::Timestamp>().value();
  auto backup = client.CreateBackup(request).get();
  if (!backup) throw std::move(backup).status();
  std::cout
      << "Backup " << backup->name() << " of " << backup->database()
      << " of size " << backup->size_bytes() << " bytes as of "

Copy a backup

Console

1. In the Google Cloud console, go to the Spanner Instances page.

   Go to Instances

2. Click the instance that contains the database that you want to copy.

3. Click the database.

4. In the navigation pane, click Backup/Restore.

5. In the Backups table, select Actions for your backup and click Copy.

6. Fill out the form by choosing a destination instance, providing a name, and selecting an expiration date for the backup copy.

7. Click Copy.

To check the progress of a copy operation, see Check the operation progress.

If the operation takes too long, you can cancel it. For more information, see Cancel a long-running instance operation.

Note: If you are copying to a different instance, the copy backup operation appears in the destination instance containing the copied backup, not the instance containing the source backup. The Google Cloud console doesn't support copying a backup to an instance in a different project. To copy a backup to a different project, use the Google Cloud CLI, client libraries, REST APIs, or RPC APIs.

gcloud

To copy a backup to a different instance in the same project, use gcloud spanner backups copy:

gcloud spanner backups copy \
  --source-instance=test-instance \
  --source-backup=example-db \
  --destination-instance=backup-instance \
  --destination-backup=copied-backup \
  --expiration-date=2022-03-30T10:49:41Z

To copy a backup to a different instance in a different project:

gcloud spanner backups copy \
  --source-backup=projects/my-project/instances/test-instance/backups/example-db \
  --destination-backup=projects/backup-project/instances/backup-instance-eu/backups/copied-backup \
  --expiration-date=2022-03-30T10:49:41Z

Usage notes:

• If you choose to copy the backup to a different instance in the same project, you must create a new instance (or have one ready) for the copied backup. In the previous example, backup-instance is used. You can't create a new instance as part of the backup copy operation.
• If you choose to copy the backup to a different project, you must have another project with its own instance ready for the copied backup. In the previous example, backup-project is used. You can't create a new project as part of the backup copy operation.
• Expiration time of the backup must be at least six hours from the time the current copy request is processed and at most 366 days after the source backup create_time.

The output looks similar to the following:

createTime: '2022-03-29T22:06:05.905823Z'
database: projects/my-project/instances/test-instance/databases/example-db
databaseDialect: GOOGLE_STANDARD_SQL
encryptionInfo:
encryptionType: GOOGLE_DEFAULT_ENCRYPTION
expireTime: '2022-03-30T10:49:41Z'
maxExpireTime: '2023-03-17T20:46:33.479336Z'
name: projects/backup-project/instances/backup-instance-eu/backups/copied-backup
sizeBytes: '7957667'
state: READY
versionTime: '2022-03-16T20:46:33.479336Z'

To check the progress of a copy operation, see Check the operation progress.

Client libraries

The following code sample copies an existing backup. You can copy the backup into an instance in a different region or project. Once complete, the sample retrieves and prints some information about the newly created copied backup, such as its name, size, backup state, and version_time.

Check the operation progress

Console

1. In the Google Cloud console, go to the Spanner Instances page.

   Go to Instances

2. Click the instance that contains the database that you want to view the backup operation for.

3. Click the database.

4. In the navigation pane, click Operations. The Operations page shows a list of running operations.

gcloud

Use gcloud spanner operations describe to check the progress of an operation.

1. Get the operation ID:

   gcloud spanner operations list --instance=INSTANCE_NAME \
   --database=DATABASE_NAME --type=BACKUP
   

   Replace the following:

   • INSTANCE_NAME with the Spanner instance name.
   • DATABASE_NAME with the name of the database.

   Usage notes:

   • To limit the list, specify the --filter flag. For example:

     • --filter="metadata.name:example-db" only lists the operations on a specific database.
     • --filter="error:*" only lists the backup operations that failed.

     For information on filter syntax, see gcloud topic filters. For information on filtering backup operations, see the filter field in ListBackupOperationsRequest.

   • The --type flag is not case sensitive.

   The output looks similar to the following:

   OPERATION_ID               DONE  @TYPE                 BACKUP          SOURCE_DATABASE  START_TIME                   END_TIME
   _auto_op_123456  True  CreateBackupMetadata  example-db-backup-7  example-db       2020-02-04T02:12:38.075515Z  2020-02-04T02:22:40.581170Z
   _auto_op_234567  True  CreateBackupMetadata  example-db-backup-6  example-db       2020-02-04T02:05:43.920377Z  2020-02-04T02:07:59.089820Z
   

2. Run gcloud spanner operations describe:

   gcloud spanner operations describe OPERATION_ID \
   --instance=INSTANCE_NAME \
   --backup=BACKUP_NAME \
   

   Replace the following:

   • OPERATION_ID: The operation ID of the operation that you want to check.
   • INSTANCE_NAME: The Spanner instance name.
   • BACKUP_NAME: The Spanner backup name.

   The progress section in the output shows the percentage of the operation that's complete. The output looks similar to the following:

   done: true
   metadata:
   ...
   progress:
   - endTime: '2022-03-01T00:28:06.691403Z'
     progressPercent: 100
     startTime: '2022-03-01T00:28:04.221401Z'
   - endTime: '2022-03-01T00:28:17.624588Z'
     startTime: '2022-03-01T00:28:06.691403Z'
     progressPercent: 100
   ...
   

   If the operation takes too long, you can cancel it. For more information, see Cancel a long-running backup operation.

Cancel a backup operation

Console

The Google Cloud console doesn't support canceling a backup operation. However, you can cancel operations that take too long using the Google Cloud CLI, REST, or RPC API. For more information, see Cancel a long-running instance operation.

gcloud

Use gcloud spanner operations cancel to cancel a backup operation.

gcloud spanner operations cancel OPERATION_ID --instance=INSTANCE_NAME \
--database=DATABASE_NAME --backup=BACKUP

Replace the following:

• OPERATION_ID with the operation ID of the backup.
• INSTANCE_NAME with the Spanner instance name.
• DATABASE_NAME with the name of the database.
• BACKUP with the name of the backup.

Client libraries

The following code sample creates a backup, cancels the backup operation, and then waits until the backup operation is done. If the operation was successfully cancelled, it returns the cancelTime and an error message. If the backup operation was completed before it was cancelled, the backup exists, and you can delete it.

C++

void CreateBackupAndCancel(
    google::cloud::spanner_admin::DatabaseAdminClient client,
    std::string const& project_id, std::string const& instance_id,
    std::string const& database_id, std::string const& backup_id,
    google::cloud::spanner::Timestamp expire_time) {
  google::cloud::spanner::Database database(project_id, instance_id,
                                            database_id);
  google::spanner::admin::database::v1::CreateBackupRequest request;
  request.set_parent(database.instance().FullName());
  request.set_backup_id(backup_id);
  request.mutable_backup()->set_database(database.FullName());
  *request.mutable_backup()->mutable_expire_time() =
      expire_time.get<google::protobuf::Timestamp>().value();
  auto f = client.CreateBackup(request);
  f.cancel();
  auto backup = f.get();
  if (backup) {
    auto status = client.DeleteBackup(backup->name());
    if (!status.ok()) throw std::move(status);
    std::cout << "Backup " << backup->name() << " was deleted.\n";
  } else {
    std::cout << "CreateBackup operation was cancelled with the message '"
              << backup.status().message() << "'.\n";

Get backup information

Console

1. In the Google Cloud console, go to the Spanner Instances page.

   Go to Instances

2. Click the instance that contains the database you want to view the backup information for.

3. Click the database to open its Overview page.

4. In the navigation pane, click Backup/Restore. You can view backup information for your selected backup in the database.

gcloud

To get information about a backup, use gcloud spanner backups describe:

gcloud spanner backups describe example-db-backup-6 --instance=test-instance

The output looks similar to the following:

createTime: '2020-02-04T02:05:43.920377Z'
database: projects/my-project/instances/test-instance/databases/example-db
expireTime: '2021-02-04T02:05:43.268327Z'
name: projects/my-project/instances/test-instance/backups/example-db-backup-6
sizeBytes: '1000000000'
state: READY

Client libraries

Client libraries don't support getting backup information for a single backup. However, you can list all backups and their information in an instance. For more information, see List backups in an instance.

List backups in an instance

Console

1. In the Google Cloud console, go to the Spanner Instances page.

   Go to Instances

2. Click your instance to view all available backups and their information.

3. In the navigation pane, click Backup/Restore.

gcloud

To list all the backups in an instance, use gcloud spanner backups list:

gcloud spanner backups list --instance=test-instance

The output looks similar to the following:

To limit the list, specify the --filter flag. For example, to filter the list to only include the backups that are still being created, add --filter="state:creating". For information about filter syntax, see gcloud topic filters. For information on filtering backups, see the filter field in ListBackupsRequest.

Client libraries

The following code sample lists the backups in a given instance.

You can filter the list of returned backups (for example, filtering by name, version time, or backup expiration time) by providing a filter expression. For information on filtering syntax, see the filter parameter in List Backups.

Update the backup expiration period

Console

1. Go to the Spanner Instances page in the Google Cloud console.

   Go to the Spanner Instances page

2. Click the instance containing the database to open its Overview page.

3. Click the database to open its Overview page.

4. In the navigation pane, click Backup/Restore.

5. Click the Actions button for your selected backup, then select Update metadata.

6. Select the new expiration date.

7. Click Update.

gcloud

To update a backup's expiration period date, use gcloud spanner backups update-metadata:

gcloud spanner backups update-metadata example-db-backup-6 \
    --instance=test-instance --expiration-date=2020-05-05T00:00:00Z

The output looks similar to the following:

createTime: '2020-02-04T02:05:43.920377Z'
database: projects/my-project/instances/test-instance/databases/example-db
expireTime: '2020-05-05T00:00:00Z'
name: projects/my-project/instances/test-instance/backups/example-db-backup-6
sizeBytes: '1000000000'
state: READY

Delete a backup

Console

1. Go to the Spanner Instances page in the Google Cloud console.

   Go to the Spanner Instances page

2. Click the instance containing the database to open its Overview page.

3. Click the database to open its Overview page.

4. In the navigation pane, click Backup/Restore.

5. Click the Actions button for your selected backup, then select Delete.

6. Type the backup ID.

7. Click Delete.

gcloud

To delete a backup, use gcloud spanner backups delete:

gcloud spanner backups delete example-db-backup-1 --instance=test-instance

You must confirm the operation:

You are about to delete backup [example-db-backup-1]

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

Deleted backup [example-db-backup-1].

Client libraries

The following code sample deletes a backup and verifies that it was deleted. Deleting a backup that is still in progress both removes the backup resource and cancels the long-running backup operation.

C++

void DeleteBackup(google::cloud::spanner_admin::DatabaseAdminClient client,
                  std::string const& project_id, std::string const& instance_id,
                  std::string const& backup_id) {
  google::cloud::spanner::Backup backup(
      google::cloud::spanner::Instance(project_id, instance_id), backup_id);
  auto status = client.DeleteBackup(backup.FullName());
  if (!status.ok()) throw std::move(status);
  std::cout << "Backup " << backup.FullName() << " was deleted.\n";
}

C#

        // Make the DeleteBackup request.
        BackupName backupName = BackupName.FromProjectInstanceBackup(projectId, instanceId, backupId);
        databaseAdminClient.DeleteBackup(backupName);
