2 weeks ago - 3x5m is not actionable since we often take more than 15 minutes to actually notice any issue
- 20x5m is a lot of write churn on the backup target, which is currently only my personal NAS
- 52x1w already offers 52 weekly backups, so 120x3w goes back 6 years and overlaps 17 times with 52x1w. Hopefully we don't need to restore data that is older than 1y.
