| nh2 | Regarding the current dedup effort, can it perform the dedup on the source (AWS) side, while storing the content-addressed objects on the remote side (like bup/``bupstash does), so that the outgoing traffic deduped (cheaper egress), but storage operations are done outside of AWS (e.g. free on self-hosted Hetzner)? | 12:46:52 |

 flokli | Yes | 12:57:06 |
| flokli | We could be reading through the NARs in the AWS bucket, decompress and CDC on a EC2 instance for example, then insert chunks into some hetzner object storage. however, xz decompression takes quite a big amount of CPU, so it might be quite slow, compared to snowballing out all, and running that part at Hetzner too. | 12:58:55 |
| nh2 | flokli: How much of the code to do that does already exist? | 13:00:48 |
| flokli | We have code essentially doing everything except actually persisting the chunks (only doing bookkeeping). That was used to test dedup ratios while we very chunking parameters | 13:02:01 |

| flokli | I'm also writing some code teaching tvix-castore how to use object storage. The internal model is the same, so it'd just be a matter of plugging some of this stuff together | 13:03:40 |
