How to move file from one in another S3 Bucket after time?

i checked this thread: Is it possible to automatically move objects from an S3 bucket to another one after some time?

but i don't want to use the Glacier option, because our files a really small. Is there another option?

EDIT:

Requirement is to mark files as invalid (there is a metadata table where we change an attribute for this) and later on to delete them. (invalid means = e.g. older as some date...maybe 30 days). After that, this invalid files should be deleted after, we say 120 days.

Why to move files?

1. Separate by business requirement (invalid vs. valid files) - don't have to check this attribute again (whether it's invalid or valid)
2. less files to iterate over, if we may want to iterate over valid files
3. important: 'S3 PUT event' of new bucket can invoke a lambda function: this lambda function can do other stuff. Like change attribute (valid/invalid/deleted) in our dynamoDB table.

Yes, we can also renounce the use of moving files. But i don't see a way how to execute lambda functions after a delay of 30 days.

Best regards
