RestoreInstance - - 阿里雲

Restores the data in a backup file to a specified ApsaraDB for Redis instance.

Operation description

If your instance is a persistent memory-optimized instance or DRAM-based instance that is compatible with Redis 5.0 and the data flashback feature is enabled, you can call this operation to restore the data of a specified key to a specified point in time that is accurate to the second. Other keys are not affected. This way, you can achieve more fine-grained data restoration.
For other instance series, this operation overwrites the existing data of your instance with the backup data. Proceed with caution. We recommend that you call the CreateInstance operation to create an instance. Then, you can restore data to the new instance.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.

Request parameters

Parameter	Type	Required	Description	Example
InstanceId	string	Yes	The ID of the instance.	r-bp1zxszhcgatnx****
BackupId	string	No	The ID of the backup file. You can call the DescribeBackups operation to query the IDs of backup files.	78241****
RestoreType	string	No	The restoration mode. Default value: 0. Valid values: 0: restores data from the specified backup set. 1: restores data to a specified point in time. You can specify this value only if the data flashback feature is enabled for the instance. If you specify this value, you must also specify the RestoreTime parameter.	1
RestoreTime	string	No	The point in time to which you want to restore data. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC. Note If the data flashback feature is enabled for the instance, you can specify this parameter and the FilterKey parameter to restore the data of the specified key to the specified point in time that is accurate to the second. Other keys are not affected. This way, you can achieve more fine-grained data restoration. This parameter is available only if you set the RestoreType parameter to 1.	2021-07-06T07:25:57Z
FilterKey	string	No	The key that you want to restore. You can specify multiple keys. Separate multiple keys with commas (,). Regular expressions are supported. Note In a regular expression, an asterisk (``) matches zero or more occurrences of a subexpression that occurs before. For example, if you set this parameter to `h.llo`, strings such as `hllo` and `heeeello` are matched. This parameter is available only if you set the RestoreType parameter to 1.	key:00000007198*
TimeShift	string	No	The expiration offset time point of a key. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mmZ format. The time must be in UTC. The key expires after the remaining validity period of the key elapses based on the expiration offset time point. Note This time point must be between the specified flashback time point and the submission time of the data restoration task.	2021-07-06T08:25:57Z
