+# Context
+
+The [[Mount Remote Storage]] feature can mount one remote storage folder to one local folder.
+```
+> remote.mount -dir=/xxx -remote=cloud1/bucket
+```
+
+However, usually you may have multiple buckets in one cloud storage. How to synchronize them automatically?
+
+# Design
+
+The `weed filer.remote.sync` added a few of features:
+* Upload all changes under `/buckets` to remote storage.
+* If any buckets are created or deleted, the remote storage will also create or delete the corresponding buckets.
+* The new buckets will be automatically mounted.
+
+To do so, the `weed filer.remote.sync` process needs to know the default remote storage to create the new bucket.
+
+# Usage
+## Mount all existing remote buckets to local
+TBD
+
+## Upload local changes in `/buckets`
+```
+$ weed filer.remote.sync -createBucketAt=cloud1
+synchronize /buckets, default new bucket creation in cloud1 ...
+```
