Using S3 “infrequent access” policies

Support
1

S3 lets objects be marked “infrequent access” which substantially reduces storage costs, provided they are read, well, infrequently :upside_down_face:. I estimate that the cost saving makes sense at <1 access per month. A bucket can have a policy added which automatically applies IA to existing objects after a write. The policy can be limited to specific object name patterns.

Does using this make sense with Kopia? IOW, do commands like snapshot and maintenance run read blobs all the time for deduplication or pruning reasons?

Kopia will read all blobs with names starting with n,q,l,m frequently but will not generally read blobs starting with p (the bulk of data). So you can probably save quite a lot this way.
