Methods

CopyBackup(CopyBackupRequest, CallSettings)

public virtual Operation<Backup, CopyBackupMetadata> CopyBackup(CopyBackupRequest request, CallSettings callSettings = null)

Starts copying a Cloud Spanner Backup. The returned backup [long-running operation][google.longrunning.Operation] will have a name of the format projects/<project>/instances/<instance>/backups/<backup>/operations/<operation_id> and can be used to track copying of the backup. The operation is associated with the destination backup. The [metadata][google.longrunning.Operation.metadata] field type is [CopyBackupMetadata][google.spanner.admin.database.v1.CopyBackupMetadata]. The [response][google.longrunning.Operation.response] field type is [Backup][google.spanner.admin.database.v1.Backup], if successful. Cancelling the returned operation will stop the copying and delete the backup. Concurrent CopyBackup requests can run on the same source backup.

Parameters
Name	Description
`request`	`CopyBackupRequest` The request object containing all of the parameters for the API call.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description
`OperationBackupCopyBackupMetadata`	The RPC response.

Example

// Create client
DatabaseAdminClient databaseAdminClient = DatabaseAdminClient.Create();
// Initialize request argument(s)
CopyBackupRequest request = new CopyBackupRequest
{
    ParentAsInstanceName = InstanceName.FromProjectInstance("[PROJECT]", "[INSTANCE]"),
    BackupId = "",
    SourceBackupAsBackupName = BackupName.FromProjectInstanceBackup("[PROJECT]", "[INSTANCE]", "[BACKUP]"),
    ExpireTime = new Timestamp(),
    EncryptionConfig = new CopyBackupEncryptionConfig(),
};
// Make the request
Operation<Backup, CopyBackupMetadata> response = databaseAdminClient.CopyBackup(request);

// Poll until the returned long-running operation is complete
Operation<Backup, CopyBackupMetadata> completedResponse = response.PollUntilCompleted();
// Retrieve the operation result
Backup result = completedResponse.Result;

// Or get the name of the operation
string operationName = response.Name;
// This name can be stored, then the long-running operation retrieved later by name
Operation<Backup, CopyBackupMetadata> retrievedResponse = databaseAdminClient.PollOnceCopyBackup(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)
{
    // If it has completed, then access the result
    Backup retrievedResult = retrievedResponse.Result;
}

RestoreDatabase(RestoreDatabaseRequest, CallSettings)

public virtual Operation<Database, RestoreDatabaseMetadata> RestoreDatabase(RestoreDatabaseRequest request, CallSettings callSettings = null)

Create a new database by restoring from a completed backup. The new database must be in the same project and in an instance with the same instance configuration as the instance containing the backup. The returned database [long-running operation][google.longrunning.Operation] has a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id>, and can be used to track the progress of the operation, and to cancel it. The [metadata][google.longrunning.Operation.metadata] field type is [RestoreDatabaseMetadata][google.spanner.admin.database.v1.RestoreDatabaseMetadata]. The [response][google.longrunning.Operation.response] type is [Database][google.spanner.admin.database.v1.Database], if successful. Cancelling the returned operation will stop the restore and delete the database. There can be only one database being restored into an instance at a time. Once the restore operation completes, a new restore operation can be initiated, without waiting for the optimize operation associated with the first restore to complete.

Parameters
