Element |
Description |
---|---|
Date |
Specifies that OBS executes lifecycle rules for objects before the specified date. The date must be compliant with the ISO8601 format, and the time must be compliant with the UTC format of 00:00:00. For example, 2018-01-01T00:00:00.000Z indicates that objects whose last modification time is earlier than 2018-01-01T00:00:00.000Z are deleted or transitioned to another storage class. Objects whose last modification time is equal to or later than the specified time are not deleted or transitioned to another storage class. Type: string Parent: Expiration, Transition |
Days |
Specifies the number of days (since the latest update to the latest object version) after which the lifecycle rule is executed. Type: integer Parent: Expiration, Transition |
StorageClass |
The storage class to which the object is transitioned. Type: string Value options: WARM, COLD Parent: Transition, NoncurrentVersionTransition |
Transition |
Transition time and the object storage class after transition (valid only for the latest object version). Type: XML Child: Date or Days Parent: Rule |
Expiration |
Container for the object expiration rule. Type: XML Child: Date or Days Parent: Rule |
ID |

NoncurrentDays |
Number of days when the specified rule takes effect after the object becomes a historical version. Type: integer Parent: NoncurrentVersionExpiration, NoncurrentVersionTransition |
NoncurrentVersionTransition |
Transition time of historical object versions and the object storage class after transition. Type: XML Child: NoncurrentDays, StorageClass Parent: Rule |
NoncurrentVersionExpiration |
Container for the expiration time of objects' historical versions. If versioning is enabled or suspended for a bucket, you can set NoncurrentVersionExpiration to delete objects whose life cycles have expired. Type: XML Child: NoncurrentDays Parent: Rule |
AbortIncompleteMultipartUpload |
Container for specifying when the not merged parts (fragments) in an incomplete upload will be deleted. Type: XML Child: DaysAfterInitiation Parent: Rule |
DaysAfterInitiation |
Specifies the number of days since the initiation of an incomplete multipart upload that OBS will wait before deleting the not merged parts (fragments) of the upload. Type: integer Parent: AbortIncompleteMultipartUpload |
