Fields
database

string

Required for the CreateBackup operation. Name of the database from which this backup was created. This needs to be in the same instance as the backup. Values are of the form projects/<project>/instances/<instance>/databases/<database>.
version_time

Timestamp

The backup will contain an externally consistent copy of the database at the timestamp specified by version_time. If version_time is not specified, the system will set version_time to the create_time of the backup.
expire_time

Timestamp

Required for the CreateBackup operation. The expiration time of the backup, with microseconds granularity that must be at least 6 hours and at most 366 days from the time the CreateBackup request is processed. Once the expire_time has passed, the backup is eligible to be automatically deleted by Cloud Spanner to free the resources used by the backup.
name

string

Output only for the CreateBackup operation. Required for the UpdateBackup operation.

A globally unique identifier for the backup which cannot be changed. Values are of the form projects/<project>/instances/<instance>/backups/[a-z][a-z0-9_\-]*[a-z0-9] The final segment of the name must be between 2 and 60 characters in length.

The backup is stored in the location(s) specified in the instance configuration of the instance containing the backup, identified by the prefix of the backup name of the form projects/<project>/instances/<instance>.
create_time

Timestamp

Output only. The time the CreateBackup request is received. If the request does not specify version_time, the version_time of the backup will be equivalent to the create_time.
size_bytes

int64

Output only. Size of the backup in bytes. For a backup in an incremental backup chain, this is the sum of the exclusive_size_bytes of itself and all older backups in the chain.
freeable_size_bytes

int64

Output only. The number of bytes that will be freed by deleting this backup. This value will be zero if, for example, this backup is part of an incremental backup chain and younger backups in the chain require that we keep its data. For backups not in an incremental backup chain, this is always the size of the backup. This value may change if backups on the same chain get created, deleted or expired.
exclusive_size_bytes

int64

Output only. For a backup in an incremental backup chain, this is the storage space needed to keep the data that has changed since the previous backup. For all other backups, this is always the size of the backup. This value may change if backups on the same chain get deleted or expired.

This field can be used to calculate the total storage space used by a set of backups. For example, the total space used by all backups of a database can be computed by summing up this field.
state

State

Output only. The current state of the backup.
referencing_databases[]

string

Output only. The names of the restored databases that reference the backup. The database names are of the form projects/<project>/instances/<instance>/databases/<database>. Referencing databases may exist in different instances. The existence of any referencing database prevents the backup from being deleted. When a restored database from the backup enters the READY state, the reference to the backup is removed.
encryption_info

EncryptionInfo

Output only. The encryption information for the backup.
encryption_information[]

EncryptionInfo

Output only. The encryption information for the backup, whether it is protected by one or more KMS keys. The information includes all Cloud KMS key versions used to encrypt the backup. The encryption_status field inside of each EncryptionInfo is not populated. At least one of the key versions must be available for the backup to be restored. If a key version is revoked in the middle of a restore, the restore behavior is undefined.
database_dialect

DatabaseDialect

Output only. The database dialect information for the backup.
referencing_backups[]

string

Output only. The names of the destination backups being created by copying this source backup. The backup names are of the form projects/<project>/instances/<instance>/backups/<backup>. Referencing backups may exist in different instances. The existence of any referencing backup prevents the backup from being deleted. When the copy operation is done (either successfully completed or cancelled or the destination backup is deleted), the reference to the backup is removed.
max_expire_time

Timestamp

Output only. The max allowed expiration time of the backup, with microseconds granularity. A backup's expiration time can be configured in multiple APIs: CreateBackup, UpdateBackup, CopyBackup. When updating or copying an existing backup, the expiration time specified must be less than Backup.max_expire_time.
backup_schedules[]

string

Output only. List of backup schedule URIs that are associated with creating this backup. This is only applicable for scheduled backups, and is empty for on-demand backups.

To optimize for storage, whenever possible, multiple schedules are collapsed together to create one backup. In such cases, this field captures the list of all backup schedule URIs that are associated with creating this backup. If collapsing is not done, then this field captures the single backup schedule URI associated with creating this backup.
incremental_backup_chain_id

string

Output only. Populated only for backups in an incremental backup chain. Backups share the same chain id if and only if they belong to the same incremental backup chain. Use this field to determine which backups are part of the same incremental backup chain. The ordering of backups in the chain can be determined by ordering the backup version_time.
oldest_version_time

Timestamp

Output only. Data deleted at a time older than this is guaranteed not to be retained in order to support this backup. For a backup in an incremental backup chain, this is the version time of the oldest backup that exists or ever existed in the chain. For all other backups, this is the version time of the backup. This field can be used to understand what data is being retained by the backup system.

The server makes a best effort to cancel the operation, but success is not guaranteed. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.
optimize_database_operation_name

string

If exists, the name of the long-running operation that will be used to track the post-restore optimization process to optimize the performance of the restored database, and remove the dependency on the restore source. The name is of the form projects/<project>/instances/<instance>/databases/<database>/operations/<operation> where the is the name of database being created and restored to. The metadata type of the long-running operation is OptimizeRestoredDatabaseMetadata. This long-running operation will be automatically created by the system after the RestoreDatabase long-running operation completes successfully. This operation will not be created if the restore was not successful.
Union field source_info. Information about the source used to restore the database, as specified by source in RestoreDatabaseRequest. source_info can be only one of the following:
backup_info

BackupInfo

Information about the backup used to restore the database.

RestoreDatabaseRequest

The request for RestoreDatabase.

Fields
parent

string

Required. The name of the instance in which to create the restored database. This instance must be in the same project and have the same instance configuration as the instance containing the source backup. Values are of the form projects/<project>/instances/<instance>.

Authorization requires the following IAM permission on the specified resource parent:

  • spanner.databases.create
database_id

string

Required. The id of the database to create and restore to. This database must not already exist. The database_id appended to parent forms the full database name of the form projects/<project>/instances/<instance>/databases/<database_id>.
encryption_config

RestoreDatabaseEncryptionConfig

Optional. An encryption configuration describing the encryption type and key resources in Cloud KMS used to encrypt/decrypt the database to restore to. If this field is not specified, the restored database will use the same encryption configuration as the backup by default, namely encryption_type = USE_CONFIG_DEFAULT_OR_BACKUP_ENCRYPTION.
Union field source. Required. The source from which to restore. source can be only one of the following:
backup

string

Name of the backup from which to restore. Values are of the form projects/<project>/instances/<instance>/backups/<backup>.

Authorization requires the following IAM permission on the specified resource backup:

  • spanner.backups.restoreDatabase

RestoreInfo

Information about the database restore.

Fields
source_type

RestoreSourceType

The type of the restore source.
Union field source_info. Information about the source used to restore the database. source_info can be only one of the following:
backup_info

BackupInfo

Information about the backup used to restore the database. The backup may no longer exist.

RestoreSourceType

Indicates the type of the restore source.

Enums
TYPE_UNSPECIFIED No restore associated.
BACKUP A backup was used as the source of the restore.

UpdateBackupRequest

The request for UpdateBackup.

Fields
backup

Backup

Required. The backup to update. backup.name, and the fields to be updated as specified by update_mask are required. Other fields are ignored. Update is only supported for the following fields: * backup.expire_time.

Authorization requires the following IAM permission on the specified resource backup:

  • spanner.backups.update
update_mask

FieldMask

Required. A mask specifying which fields (e.g. expire_time) in the Backup resource should be updated. This mask is relative to the Backup resource, not to the request message. The field mask must always be specified; this prevents any future fields from being erased accidentally by clients that do not know about them.

UpdateBackupScheduleRequest

The request for UpdateBackupScheduleRequest.

Fields
backup_schedule

BackupSchedule

Required. The backup schedule to update. backup_schedule.name, and the fields to be updated as specified by update_mask are required. Other fields are ignored.

Authorization requires the following IAM permission on the specified resource backupSchedule:

  • spanner.backupSchedules.update
update_mask

FieldMask

Required. A mask specifying which fields in the BackupSchedule resource should be updated. This mask is relative to the BackupSchedule resource, not to the request message. The field mask must always be specified; this prevents any future fields from being erased accidentally.

UpdateDatabaseDdlMetadata

Metadata type for the operation returned by UpdateDatabaseDdl.

Fields
database

string

The database being modified.
statements[]

string

For an update this list contains all the statements. For an individual statement, this list contains only that statement.
commit_timestamps[]

Timestamp

Reports the commit timestamps of all statements that have succeeded so far, where commit_timestamps[i] is the commit timestamp for the statement statements[i].
throttled

bool

Output only. When true, indicates that the operation is throttled e.g. due to resource constraints. When resources become available the operation will resume and this field will be false again.
progress[]

OperationProgress

The progress of the UpdateDatabaseDdl operations. All DDL statements will have continuously updating progress, and progress[i] is the operation progress for statements[i]. Also, progress[i] will have start time and end time populated with commit timestamp of operation, as well as a progress of 100% once the operation has completed.
actions[]

DdlStatementActionInfo

The brief action info for the DDL statements. actions[i] is the brief info for statements[i].

UpdateDatabaseDdlRequest

Enqueues the given DDL statements to be applied, in order but not necessarily all at once, to the database schema at some point (or points) in the future. The server checks that the statements are executable (syntactically valid, name tables that exist, etc.) before enqueueing them, but they may still fail upon later execution (e.g., if a statement from another batch of statements is applied first and it conflicts in some way, or if there is some data-related problem like a NULL value in a column to which NOT NULL would be added). If a statement fails, all subsequent statements in the batch are automatically cancelled.

Each batch of statements is assigned a name which can be used with the Operations API to monitor progress. See the operation_id field for more details.

Fields
database

string

Required. The database to update.

Authorization requires the following IAM permission on the specified resource database:

  • spanner.databases.updateDdl
statements[]

string

Required. DDL statements to be applied to the database.
operation_id

string

If empty, the new update request is assigned an automatically-generated operation ID. Otherwise, operation_id is used to construct the name of the resulting Operation.

Specifying an explicit operation ID simplifies determining whether the statements were executed in the event that the UpdateDatabaseDdl call is replayed, or the return value is otherwise lost: the database and operation_id fields can be combined to form the name of the resulting longrunning.Operation: <database>/operations/<operation_id>.

operation_id should be unique within the database, and must be a valid identifier: [a-z][a-z0-9_]*. Note that automatically-generated operation IDs always begin with an underscore. If the named operation already exists, UpdateDatabaseDdl returns ALREADY_EXISTS.
proto_descriptors

bytes

Optional. Proto descriptors used by CREATE/ALTER PROTO BUNDLE statements. Contains a protobuf-serialized google.protobuf.FileDescriptorSet. To generate it, install and run protoc with --include_imports and --descriptor_set_out. For example, to generate for moon/shot/app.proto, run

$protoc  --proto_path=/app_path --proto_path=/lib_path \
         --include_imports \
         --descriptor_set_out=descriptors.data \
         moon/shot/app.proto

For more details, see protobuffer self description.
