S3 Lifecycle - Exclude Prefix

Question

If I have a prefix **Folder-1** which has a rule to keep contents live for 6 months and beyond 6 months to move the contents to Glacier. I would like to exclude **Folder-1.1** and **Folder-1.2** from this policy and have the data retained for 2 years. So, if I create an explicit rule on **Folder-1/Folder-1.1** and **Folder-1/Folder-1.2** to retain anything for 2 years, will the Glacier rule apply to all the rest of the folders except Folder-1.1 and Folder-1.2?

Prefix structure is as follows:

Folder-1/
        |-- Folder-1.1
        |-- Folder-1.2
        |-- Folder-1.3
        |-- Folder-1.4

I don’t think S3 supports exclude rules currently in the Lifecycle management. Any recommendations on how this can be achieved?

Accepted Answer

S3 is a key-value object storage service, there is no concept of ‘folder’ but 'prefix', for lifecycle rule if a rule is applied on a shorter prefix, it will take effect on the whole sub prefixes' objects, including 1.1 and 1.2. So yes applying the 1/ 'folder' will make 'folder' 1.1 and 1.2 being treated as the same as 1.3 and 1.4.

You can use object tag as the filter instead of prefix e.g creating a tag on all the objects with prefix 1/1.3 1/1.4 and use a single rule, or only applying lifecycle rules on 1/1.3 and 1/1.4.

Answer

Is it possible to create the tag only for objects that should be excluded from file movement rules?

For example:

```
- folderA
---folder1
------- file1
------- file2
---folder2
------- file3
------- file4
```

If I want to exclude folder 1, I create the tag only on folder 1.

Can I use this approach? Or it is mandatory create a tag for each folders?

Thanks
