Has anyone tried using a GCP bucket (or S3) with Object lifecycle management? i’m wondering if this would work to reduce cost of storage but I don’t know enough about kopia maintenance or how the differential part of snapshots works in terms of operations needed and downloads of the data blobs to even get a rough estimate

I’m basically thinking something like starting blobs in Standard storage class and then have a bucket rule to move blobs to Coldline storage after 1 month. This would allow me to access new blobs early, maybe even to delete files without minimum storage duration but then pay less once a blob gets older. This would work in theory if maintenance and differential backups work purely on metadata and not on the actual data blobs right?

Public clouds have [crazy pricing formulas](https://cloud.google.com/storage/pricing) so it’s hard to estimate without committing. That’s why I rather ask if someone has tried to do this. I imagine S3 must have something similar. Any advice?

I have never done this, but this might be a good starting point:
