Problem

As a user of Snellius or Lisa, you want to access the data archive, but you get the following error.

$ cd /archive/<username>
-bash: cd: /archive/<username>/: Permission denied

Solutions

You are trying to access the archive folder of another user:

If you are trying to access the archive folder, you do not have permission to do so.
If you need access to this folder, you can ask him to add you: Access Control Lists (ACLs). 

You are trying to access the archive folder of yourself:

This can only happen if you have two logins <username1> and <username2>. 
You are logged in with <username1> to Lisa or Snellius.

Find out which login you are using:  

$ whoami
username1

If you want to access the data archive of <username2>, you can do the following:

$ scp sourcefile <username2>@archive.surfsara.nl:<username2>
