Test: `curl -sI https://s3.ap-southeast-2.amazonaws.com`. - [ ] **Total offsite media size** — confirm what must go cold (Site media + Immich ~472G + archives). `du -sh` per path → refine cost model. - [ ] **Existing backup inventory confirmed** — Borg local `.13` (daily 04:00), rsync→`.35`(05:00), archive→`.23`(06:00). These stay as-is; AWS is additive. ## Output - Approved list of source paths for offsite seeding. - Confirmed AWS region + account login ready. - Go/no-go for Phase 1. --- *Work-in-progress log for this phase tracked in [[Migration Work Log]].*
