Can files uploaded to Amazon S3 get auto-deleted after few days?

Question

Amazon S3 API has added Object Expiration which deleted all the files uploaded within a folder after few days.

Is it possible to make the same for each file from the day it was uploaded?

For example when I upload foo.png, after X days, delete that file not all the files within the folder.

Answer 1

Your file path is not more than a prefix in S3. So, if you have a structure as follows:

/  
|  
+--folder1   
    |  
    +--folder2  
    |   
    +--folder3  
    |   |  
    |   +--foo.png  
    |   |  
    |   +--foo2.png  
    |  
    +--bar.png  

And you want your rule to apply only to foo.png, set it to "folder1/folder3/foo.png" (there will be only one file matching the "entire-name" prefix in your bucket).

But be aware of the limits regarding number of rules. From Object Expiration docs:

To set an object’s expiration, you add a lifecycle configuration to your bucket, which describes the lifetime of various objects in your bucket. A lifecycle configuration can have up to 100 rules. Each rule identifies an object prefix and a lifetime for objects that begin with this prefix. The lifetime is the number of days since creation when you want the object removed.
