Snapshot rotation with Amazon S3

Hi,

Backup to amazon S3 bucket works well (thanks !)

I have a question about backups rotation.

In the snapshot config, I set “Maximum number of local archives” = 3

So I can see a maximum of 3 archive files from the WordPress backend.

But in my Amazon S3 bucket, all archives are kept.

Do you have an advise to force backup rotation here too ? (because costs will apply if all my backups are still conserved !)

Thanks,

Aldric
