# Step 07 — an S3-class annex remote, and the local → S3 move

Step 3 gave your sessions root a local payload store — durable against a wiped checkout, not against that disk, and invisible to a second machine. This step moves that payload into an S3-class bucket of yours (AWS S3, Cloudflare R2, MinIO, SeaweedFS) and clones the root on machine two, so both machines share one durable copy that the daemon keeps current every ten minutes.
