public Operation getBackupOperation()

Description copied from interface: BackupAwareOperation

Creates the BackupOperation responsible for making the backup.

Returns:

the created BackupOperation.

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Returns:

type id
