Properties
BackupName
public BackupName BackupName { get; set; }BackupName-typed view over the Name resource name property.
| Property Value | |
|---|---|
| Type | Description |
BackupName |
|
BackupSchedules
public RepeatedField<string> BackupSchedules { get; }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.

CreateTime
public Timestamp CreateTime { get; set; }Output only. The time the
[CreateBackup][google.spanner.admin.database.v1.DatabaseAdmin.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.
| Property Value | |

| Type | Description |
Timestamp |

Database
public string Database { get; set; }Required for the
[CreateBackup][google.spanner.admin.database.v1.DatabaseAdmin.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>.

public DatabaseName DatabaseAsDatabaseName { get; set; }Google.Cloud.Spanner.Common.V1.DatabaseName-typed view over the Database resource name property.

DatabaseDialect
public DatabaseDialect DatabaseDialect { get; set; }Output only. The database dialect information for the backup.
| Property Value | |

|
EncryptionInfo
public EncryptionInfo EncryptionInfo { get; set; }Output only. The encryption information for the backup.
| Property Value | |
|---|---|
| Type | Description |
EncryptionInfo |
|
EncryptionInformation
public RepeatedField<EncryptionInfo> EncryptionInformation { get; }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 eachEncryptionInfo` 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.
| Property Value | |
|---|---|
| Type | Description |

ExclusiveSizeBytes
public long ExclusiveSizeBytes { get; set; }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.
| Property Value | |
|---|---|
| Type | Description |
long |
|
ExpireTime
public Timestamp ExpireTime { get; set; }Required for the
[CreateBackup][google.spanner.admin.database.v1.DatabaseAdmin.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.
| Property Value | |
|---|---|
| Type | Description |
Timestamp |
|
FreeableSizeBytes
public long FreeableSizeBytes { get; set; }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.
| Property Value | |
|---|---|
| Type | Description |
long |
|
IncrementalBackupChainId
public string IncrementalBackupChainId { get; set; }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.
| Property Value | |
|---|---|
| Type | Description |
string |
|
MaxExpireTime
public Timestamp MaxExpireTime { get; set; }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.
| Property Value | |
|---|---|
| Type | Description |
Timestamp |
|
Name
public string Name { get; set; }Output only for the [CreateBackup][google.spanner.admin.database.v1.DatabaseAdmin.CreateBackup] operation. Required for the [UpdateBackup][google.spanner.admin.database.v1.DatabaseAdmin.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>.
| Property Value | |
|---|---|
| Type | Description |
string |
|
OldestVersionTime
public Timestamp OldestVersionTime { get; set; }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.
| Property Value | |
|---|---|
| Type | Description |
Timestamp |
|
ReferencingBackups
public RepeatedField<string> ReferencingBackups { get; }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.
| Property Value | |
|---|---|
| Type | Description |
RepeatedFieldstring |
|
ReferencingBackupsAsBackupNames
public ResourceNameList<BackupName> ReferencingBackupsAsBackupNames { get; }BackupName-typed view over the ReferencingBackups resource name property.

ReferencingDatabases
public RepeatedField<string> ReferencingDatabases { get; }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.
| Property Value | |
|---|---|
| Type | Description |
RepeatedFieldstring |
|
ReferencingDatabasesAsDatabaseNames
public ResourceNameList<DatabaseName> ReferencingDatabasesAsDatabaseNames { get; }Google.Cloud.Spanner.Common.V1.DatabaseName-typed view over the ReferencingDatabases resource name property.

VersionTime
public Timestamp VersionTime { get; set; }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.
