RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
DBInstanceId	string	Yes	The instance ID. You can call the `DescribeDBInstances` operation to query instance IDs.	rm-uf6wjk5****
BackupPolicyMode	string	No	The backup type. Valid values: DataBackupPolicy: data backup LogBackupPolicy: log backup	DataBackupPolicy
CompressType	string	No	The backup compression type. Valid values: 0: No compression. 1: zlib compression. 2: Parallel zlib compression. 4: QuickLZ compression, which enables database and table recovery. 8: QuickLZ compression, which does not support database and table recovery.	1
ReleasedKeepPolicy	string	No	The retention policy for archived backups of a deleted MySQL instance. Valid values: None: No backups are retained. Lastest: The last backup is retained. All: All backups are retained.	Lastest

Response elements

Element	Type	Description	Example
	object	The response parameters.
ArchiveBackupKeepCount	string	The number of archive backups that are retained for the MySQL instance.	1
ArchiveBackupKeepPolicy	string	The retention policy for archive backups of the MySQL instance.	ByMonth
ArchiveBackupRetentionPeriod	string	The number of days for which the archive backups of the MySQL instance are retained.	365
BackupInterval	string	The backup interval. Unit: minutes. For a MySQL instance, the value of this parameter indicates the frequency of snapshot backups rather than the backup cycle. For a SQL Server instance, the value of this parameter indicates the frequency of log backups.	30
BackupLog	string	Indicates whether log backup is enabled. Valid values: Enable Disabled For SQL Server instances: The value is Enable only when the log backup frequency is every 5 minutes. If the log backup frequency is every 30 minutes or is the same as the data backup frequency, this parameter returns Disabled. In this case, the value of the BackupInterval parameter is the actual log backup frequency.	Enable
BackupMethod	string	The backup method for an instance of SQL Server on Cloud Disk. Valid values: Physical: physical backup Snapshot: snapshot backup	Physical
BackupPriority	integer	The backup setting for the secondary instance of an SQL Server Enterprise Cluster Edition instance. Valid values: 1: Backs up data on the secondary instance first. 2: Backs up data on the primary instance only. Note This parameter is returned only if the value of `SupportModifyBackupPriority` is `True`.	2
BackupRetentionPeriod	integer	The number of days for which data backups are retained.	7
Category	string	Indicates whether the second-level backup feature is enabled for a MySQL or PostgreSQL instance. This feature provides backup with per-second granularity. Valid values: Flash: Second-level backup is enabled. Standard: Second-level backup is disabled. Note This parameter takes effect only when the `BackupPolicyMode` parameter is set to `DataBackupPolicy`.	Standard
CompressType	string	The backup compression method. Valid values: 0: Backups are not compressed. 1: Backups are compressed by using zlib. 2: Backups are compressed by using parallel zlib. 4: Backups are compressed by using QuickLZ. This compression method supports database and table recovery. 8: Backups are compressed by using QuickLZ. This compression method does not support database and table recovery.	1
EnableBackupLog	string	Indicates whether log backup is enabled. Valid values: 1: enabled 0: disabled For SQL Server instances: The value 1 is returned only when the log backup frequency is every 5 minutes. If the log backup frequency is every 30 minutes or the same as the data backup frequency, the value 0 is returned. In this case, the value of the BackupInterval parameter is the actual log backup frequency.	1
EnableIncrementDataBackup	boolean	Indicates whether incremental backup is enabled for the SQL Server instance. Valid values: True False	True
EnablePitrProtection	boolean	Indicates whether point-in-time recovery (PITR) is enabled for the MySQL instance. PITR is an enhanced version of log backup. Valid values: True False Note For more information, see Configure a PITR policy.	True
HighSpaceUsageProtection	string	Indicates whether to forcibly delete binary log files from a MySQL instance if its disk usage exceeds 80% or the remaining disk space is less than 5 GB.

LocalLogRetentionSpace	string	The maximum percentage of disk space that local log files can occupy on the MySQL instance.	30
LogBackupFrequency	string	The log backup frequency of the SQL Server instance. Valid values: LogInterval: A log backup is performed every 30 minutes. If this parameter is not returned, the log backup frequency is the same as the data backup cycle that is specified by the PreferredBackupPeriod parameter.	LogInterval
LogBackupLocalRetentionNumber	integer	The number of local binary log files to retain for the MySQL instance.	60
LogBackupRetentionPeriod	integer	The number of days for which log backups are retained.	7
PitrRetentionPeriod	integer	The number of days for which PITR is available for the MySQL instance.	7
PreferredBackupPeriod	string	The day of the week on which to perform a data backup. Separate multiple values with commas (,). Valid values: Monday Tuesday Wednesday Thursday Friday Saturday Sunday	Monday,Wednesday,Friday,Sunday
PreferredBackupTime	string	The time window in which to perform a data backup. The time is in the HH:mmZ-HH:mmZ format and is displayed in UTC.	15:00Z-16:00Z
