Parameter Description

Parameter	Optional or Mandatory	Description
bucket	Mandatory	The bucket name
key	Mandatory for restoring a single object whose storage class is cold Optional for batch restoring objects whose storage class is cold	The name of the object to be restored or the name prefix of the objects to be restored in batches NOTE: If this parameter is left blank when batch restoring objects, all objects whose storage class is cold in the bucket are restored.
d	Optional (additional parameter)	The storage duration after objects whose storage class is cold are restored, in days. The value ranges from 1 to 30. The default value is 1.
t	Optional (additional parameter)	The options for restoring objects. Possible values are: standard expedited NOTE: expedited indicates that objects can be quickly restored from Archive storage within 1 to 5 minutes. standard indicates that objects can be restored from Archive storage within 3 to 5 hours. If this parameter is not configured, an expedited restore is used by default.
versionId	Optional for restoring a single object whose storage class is cold (additional parameter)	The version ID of the to-be-restored object whose storage class is cold
fr	Optional for restoring a single object whose storage class is cold (additional parameter)	Generates an operation result file when restoring a single object whose storage class is cold.
f	Optional for batch restoring objects whose storage class is cold (additional parameter)	Runs in force mode.
r	Mandatory for batch restoring objects whose storage class is cold (additional parameter)	Restores objects whose storage class is cold in batches by object name prefix.
v	Optional for batch restoring objects whose storage class is cold (additional parameter)	Restores versions of objects whose storage class is cold in batches by object name prefix.

By default, the maximum size of a single result file is 30 MB and the maximum number of result files that can be retained is 1,024. You can set the maximum size and number by configuring recordMaxLogSize and recordBackups in the configuration file.
