+## Automated Tiering
+In `master.toml` generated by `weed scaffold -config=master`, you can adjust the `master.maintenance` script section:
+```
+[master.maintenance]
+# periodically run these scripts are the same as running them from 'weed shell'
+scripts = """
+  lock
+  volume.tier.upload -dest s3 -fullPercent=95 -quietFor=1h
+  ...
+  unlock
+"""
+```
 
-
-
+Or you can run the `weed shell` periodically in some cron job:
+```
+echo "lock;volume.tier.upload -dest s3 -fullPercent=95 -quietFor=1h;unlock" | weed shell
+```
