Later, any metadata operations can be invoked locally, and respond very fast.
## Write Back changes to Remote Storage
If the mounted directory is only for reading, you can start to use it.
If you want to change files in the mounted directory, a separate process `weed filer.remote.sync -dir=xxx` should be started.
This process will listen to filer change events, and write any changes back to the remote storage.
```
weed filer.remote.sync -filer=<filerHost>:<filerPort> -dir=xxx
```
## Unmount a Remote Storage
Similarly, running `remote.unmount -dir=xxx` can unmount a remote storage. However, this means all cached data and metadata will be lost.
And if `weed filer.remote.sync -filer=<filerHost>:<filerPort> -dir=xxx` was not run, the updated local data have not been uploaded to the remote storage, so these local changes will be lost.
## Benefits to Cache Metadata
### Speed up meta data operations
