 ## Create storage volume
 
 ### Why a storage volume?
-In most cases you need to create a storage volume before you create a workspace. A workspace has limited storage and is temporary; all data stored on the workspace itself are deleted when a workspace is deleted. You can see a storage volume as a USB stick that you can attach to a workspace. A storage volume is persistent, so when you remove a workspace, all data on the storage volume will remain there. Storage volumes have good performance and are suitable for I/O-intensive computing tasks.

 When you created a workspace and chose to attach a storage volume to the workspace (see below), the storage volume can be found under the directory path: `/data`
 Typically you want to create a project folder on the storage volume (e.g. `/data/my_storage/my_project`).
 
+### Attaching and detaching storage volumes
+You can attach/detach storage volumes to a workspace when a workspace is in paused state ([instructions](https://servicedesk.surf.nl/wiki/spaces/WIKI/pages/19825226/External+storage+volumes#Externalstoragevolumes-Attach%2FDetachStorage)). It is possible to attach multiple storage volumes to a workspaces at the same time.

 ## Create a workspace
 A workspace can also be called a 'Virtual Machine' or a 'Server'. It is a temporary 'remote' machine that you can login to and that has you can use to perform analyses or model runs. You 'pay' for the machine with the credits from your wallet until the workspace is being 'paused' or 'deleted'. The more compute power you select the more credits it costs and the sooner your wallet will be empty.

 For longer-living workspaces, UU also requires use of scanning tools to scan active VRE's for security vulnerabilities. If the scan gives cause, the UU will contact you with the request to update software on VRE, and/or to take additional measures. If you intend to run longer-running workspaces, please [contact us](contact.qmd) and we can help to install the necessary scanning software.
 
 ## Data storage and – backup
-A VRE is not backed up. The user is responsible for backing up the (processed) data and/or configuration of the VRE. Make sure to regularly synchronize data and scripts with approved platform like Yoda, Research Drive and GitHub.

+By synchronizing your project folder to online storage, you also ensure that you can safely delete workspaces and storage volumes when you not plan to use Research cloud in the near future and save credits.
