## Cold Storage — AWS Glacier Deep Archive
rsync handles local and remote backups, but for true offsite cold storage — disaster recovery, archival copies you rarely need to retrieve — AWS Glacier Deep Archive is the cheapest option at ~$1/TB/month.
Upload files directly to an S3 bucket with the `DEEP_ARCHIVE` storage class:
```bash
# Single file
aws s3 cp backup.tar.gz s3://your-bucket/ --storage-class DEEP_ARCHIVE
# Entire directory
aws s3 sync /backup/offsite/ s3://your-bucket/offsite/ --storage-class DEEP_ARCHIVE
```
**When to use it:** Long-term backups you'd only need in a disaster scenario — media archives, yearly snapshots, irreplaceable data. Not for anything you'd need to restore quickly.
**Retrieval tradeoffs:**
- **Standard retrieval:** 12 hours, cheapest restore cost
- **Bulk retrieval:** Up to 48 hours, even cheaper
- **Expedited:** Not available for Deep Archive — if you need faster access, use regular Glacier or S3 Infrequent Access
**In the MajorsHouse backup strategy**, rsync handles the daily local and cross-host backups. Glacier Deep Archive is the final tier — offsite, durable, cheap, and slow to retrieve by design. A good backup plan has both.
## Gotchas & Notes
- **Test with `--dry-run` first.** Especially when using `--delete`. See what would be removed before actually removing it.
